Si-TPV 3100-85A: A New Silicone-Based Thermoplastic Elastomer for Premium Soft-Touch Consumer Electronics and Wearables

Premium soft-touch elastomer with non-sticky surface, low VOC, and efficient overmolding performance.

The Growing Demand for Better Soft-Touch Materials

As consumer electronics, smart wearable devices, and automotive interiors continue moving toward more premium tactile experiences, manufacturers are under increasing pressure to develop products that not only look refined, but also maintain long-term comfort, durability, and surface stability. Traditional soft-touch materials often struggle to meet these evolving expectations. Conventional TPU materials can provide excellent mechanical strength and abrasion resistance, yet their surfaces may gradually become sticky, attract dust, or lose their pleasant feel after prolonged use. Standard TPE compounds may rely on plasticizers that can migrate over time, causing blooming, oil bleeding, or unstable surface performance. Liquid silicone rubber offers excellent softness and skin comfort, but its complex curing processes and higher manufacturing costs can limit production efficiency.

To address these challenges, SILIKE developed Si-TPV 3100-85A, a next-generation silicone-based thermoplastic elastomer engineered to combine silicone-like tactile comfort with the processing advantages of thermoplastic materials.

Silicone-Like Touch with Long-Term Surface Stability

Si-TPV 3100-85A is designed using a dynamic vulcanized structure in which fully cross-linked silicone rubber particles are uniformly dispersed within a TPU continuous phase. This advanced microstructure allows the material to balance the durability and processing flexibility of TPU with the silky touch and surface comfort commonly associated with silicone rubber.

One of the most significant advantages of Si-TPV 3100-85A is its ability to maintain a long-term silky skin-friendly feel without relying on sprayed coatings, surface oils, or additional tactile treatments. Unlike many traditional soft elastomers that become tacky or glossy after extended handling, the soft-touch effect of Si-TPV 3100-85A is built directly into the material itself. As a result, the surface remains dry, smooth, and comfortable even during prolonged contact with skin or repeated daily use. This characteristic is becoming increasingly important as consumers place greater value on tactile quality and premium surface experience in electronic devices and wearable products.

Non-Sticky Performance Without Plasticizers

Surface cleanliness and appearance retention are also major considerations for manufacturers developing high-end consumer products. Dark-colored TPU and TPE materials often suffer from dust adsorption, fingerprint visibility, and sweat mark accumulation, especially in applications involving frequent handling. Si-TPV 3100-85A helps reduce these common issues by offering improved stain resistance and lower dust attraction while maintaining a clean matte appearance. The material’s non-sticky surface performance makes it particularly attractive for products such as smartwatch straps, wireless earbuds, VR accessories, smartphone protective components, and portable electronics where long-term appearance stability directly influences perceived product quality.

Another important feature of Si-TPV 3100-85A is its formulation without plasticizers or softening oils. Many conventional elastomers depend on these additives to achieve softness and flexibility, but over time they may migrate to the material surface, resulting in oil bleeding, sticky feel, or reduced durability. By eliminating these additives, Si-TPV 3100-85A helps manufacturers achieve lower VOC emissions, cleaner surfaces, and more stable long-term tactile performance. These characteristics are especially valuable in wearable devices, automotive interiors, and skin-contact applications where comfort, environmental stability, and material safety are increasingly important.

In addition to its tactile benefits, Si-TPV 3100-85A offers a balanced combination of mechanical performance and flexibility suitable for demanding applications. With a Shore A hardness around 83A, the material provides a stronger structural feel than ultra-soft elastomers while still maintaining excellent comfort and elasticity. Its tensile strength, tear resistance, and elongation performance allow designers to create products that combine ergonomic comfort with reliable durability, making the material suitable for both soft-touch decorative components and functional structural applications.

Excellent Overmolding and Processing Efficiency

The material also supports advanced overmolding and multi-material product designs. Si-TPV 3100-85A demonstrates excellent bonding compatibility with engineering plastics including PC, ABS, PC/ABS, TPU, and PA, enabling efficient two-shot injection molding and integrated soft-touch overmolding processes. For manufacturers seeking to eliminate secondary coating operations while improving product durability, this capability offers substantial production advantages. The material allows designers to create seamless soft-touch interfaces and ergonomic grip structures without relying on adhesives or additional finishing processes.

Compared with traditional liquid silicone rubber, Si-TPV 3100-85A also delivers significant manufacturing efficiency advantages. The material can be processed using standard thermoplastic manufacturing methods such as injection molding, extrusion, co-extrusion, and two-shot molding. Unlike LSR systems that require vulcanization curing stages and more complex production control, Si-TPV 3100-85A enables faster production cycles, easier recyclability, and simplified processing conditions. These benefits help manufacturers reduce processing complexity while supporting high-volume production efficiency for modern consumer electronics and wearable products.

Its silicone-like feel, non-sticky surface performance, and efficient thermoplastic processing make it highly suitable for next-generation consumer and industrial products.

In consumer electronics, the material can be used for smartphone protective components, tablet accessories, wireless earbuds, charging device housings, portable gaming accessories, and smart device covers that require a clean matte appearance and comfortable hand feel during long-term use.

For smart wearable devices, Si-TPV 3100-85A is particularly suitable for smartwatch straps, fitness tracker bands, VR accessories, AR wearable components, and skin-contact electronic products where softness, low VOC performance, and long-lasting comfort are critical.

In automotive interiors, the material offers an ideal solution for soft-touch decorative parts, center console surfaces, armrests, steering-related grip areas, and interior trim components that demand both premium tactile experience and long-term durability.

The material is also well suited for ergonomic tool grips, sports equipment handles, portable device grips, and overmolded structural components where designers need a balance of elasticity, mechanical strength, and comfortable touch.

Thanks to its excellent bonding compatibility with PC, ABS, PC/ABS, TPU, and PA, Si-TPV 3100-85A supports advanced overmolding and multi-material product designs, enabling manufacturers to create seamless soft-touch structures while simplifying production processes.

By combining silicone comfort with thermoplastic manufacturability, Si-TPV 3100-85A opens new possibilities for high-end applications requiring premium aesthetics, durable performance, and scalable industrial production.

Powder Coat Booths

For those larger-sized parts, or smaller quantity runs, we have 2 independent powder coat booths and ovens. The quality, durability and affordability of today’s powder coating finishes make this the process of choice for world-class companies.

Powder coating advantages over other forms of coating are many. Materials used in the Powder coating process can be metals and non-metals that come in a multitude of thicknesses, textures, colors, etc. Another of Powder coating’s biggest advantages over conventional coatings is its ability to create finishes in many different textures. Powder Coating Booths allow us the ability to apply these advantages to large products.

Wet Paint Line

Tri-State Fabricators runs a full-service conveyor line for painting. Wet painting can provide protection or decoration to many different part styles. From start to finish, every project is easier to undergo random and point-based inspection by our skilled painting team.

Advantages to our Wet Paint Line are these lines start with product prep and ends with a thorough inspection of a high quality finished product. Our ability to complete large and small projects with a superior finish and doing so in a timely and economical fashion. This passes along the savings in production to our customers. When powder coating ins not an option, our Wet Paint Line gets the job done right the first time.

Wet Paint Booths

When the parts get big and heavy we roll-out our custom paint racks and oversize booth. By utilizing our partnerships with all the major paint brands, we can match virtually any color with wet paint.

The advantages of having access to a Wet Paint Booth are many. Large projects of many different shapes can be loaded into the booth. The Wet Paint Booth offers an environment that is much more controlled than a typical parts painting operation.

Not only are they used because of their controlled environment, but they’re are also advantageous when it comes to applying paint to parts that are needed in industries that require specialty coatings such as medical, aerospace, etc.

Military CARC

Our military forces have some very high standards when it comes to the finish of their vehicles and equipment. From the first pre-treatment step to final coat, it takes a great deal of knowledge and experience to protect the men and women of our armed forces. They deserve only the best, and Tri-State Fabricators provides it.

All of our processes are closely monitored by our staff and management teams. Both of which are highly trained in the processes of metal fabrication and finishing. Tri-State Fabricators’ goal is to always fully satisfy each and every customer, including the military. We will always put a 110% into what we do.

Glass-Bead Blasting

Abrasive media blasting is an excellent way to remove old paint, rust, and increase the paint/powder adhesion. Glass beads produce a much smoother and brighter finish than angular abrasives; leaving the part clean yet without any dimensional change. Chemically inert and environmentally friendly, we can recycle our beads approximately 30 times; making them a more preferred method of metal cleaning or surface finishing.

Advantages to Glass Bead Blasting are many. Glass bead blast media is used when a project is needing rough surfaces need to become smooth for applications of coatings such as paint. It is typically used to clean paint and rust from a product surface without deforming the surface it is being used on. Overall, compared to many other blasting media, Glass Bead Blasting is a very economical choice and those savings are always passed on to our customers.

Part Washing

Tri-State Fabricators utilize a zinc phosphate wash to clean and etch the material to ensure the best paint adhesion possible. The unique design of our 3-stage wash system does the work like a 5-stage. From Cleaning and rinsing to conversion coating and post-treatment, Our Part Washing process is a complete service and works throughout the fabrication service and the finishing service.

Along with the previously mentioned benefits, Curing is a vital chemical reaction that leaves the product finish hard and relatively safe from mild abrasion and aggressive corrosion. This process can be done in more than one way; ambient air-dry or in curing ovens at temps that exceed 240°.

Burn-Off Oven

From fixing paint mistakes (someone else’s of course) to simply cleaning our paint line hooks, our burn-off oven is put to good use. After a quick burn-off, a little clean up, and a fresh coat of paint, your parts will look better than new.

Why does our Burn-Off Oven work so well? Because super heating the air around parts turns the materials into ashes. From paint and powder coatings to rubber and machining oils, high temps do the job without degrading the integrity of the part.

Masking

Masking is a vital part of producing high quality products. We have die-cut masking patterns to protect machined surfaces as well as a wide range of plugs and caps to protect threaded holes and bolts. We provide permanent and temporary masking.

Masking allows the selected sections of a product to be protected from a fabrication or finishing service. This can be with both chemicals when etching and tapes, paints when only finishing just a section of the product. Masking is great in aiding the customization process of a project.

Screen Printing

Screen printing is a photographic process that transfers artwork onto a porous nylon screen which allows colored ink to flow through the screen and be deposited on an aluminum or plastic component. We can generally have just about any design created onto a screen for your parts.

Some of the advantages of Screen Printing are, brand recognition for your business displaying on your products, assembly instructions, product warnings/hazards, etc. Tri-State Fabricators produces Screen Printing of the highest quality so you know it’s durable.

Metal Finishing

Metal Finishing is the art of treating the exterior portion of product, often metal but can also be made of other materials, so that the surface is clean and free of any debris. Then the process of applying coats or either paint of powder coat takes place. This coating process improves the quality of the product in both appearance and resistance to wear and corrosion.

Tri-State Fabricators, Inc., understands that a project typically isn’t complete until a high-quality finish has been added to your product. This is why our painting and powder coating teams continuously inspect the products throughout the Metal Finishing process.
