Chenvix SkinTouch
Soft-Touch Material for Injection-Molded Products
A silicone-like soft touch combined with thermoplastic processing, durability and design flexibility.
- Soft Touch
- Injection Moldable
- Overmolding Compatible
- Product-Ready Material
What Is SkinTouch?
SkinTouch is a silicone-based thermoplastic elastomer (Si-TPV) that delivers a silicone-like velvet touch with standard thermoplastic injection molding efficiency.
Unlike conventional soft-touch materials that turn oily, attract dust, or require specialized silicone presses, SkinTouch runs on conventional injection presses, bonds directly to rigid substrates, and keeps its clean, dry feel for the product lifetime.
- Silicone-like soft touch without tackiness
- Thermoplastic processing for fast cycles
- Overmolding ready for PC / ABS / PA
- Design flexibility for thin-wall parts
Si-TPV pellets -- dry, free-flowing, compatible with standard hopper dryers and injection units.
SkinTouch Material Performance
Engineered for products that are touched daily. Where verified data is pending, technical data is available on request.
Soft and Skin-Friendly Touch
Velvet, dry feel with low friction. Comfortable for prolonged skin contact in wearables and grips.
Durable Surface
Abrasion and scratch resistant soft layer. No spray coating to peel or wear off.
Technical Data Available on Request
Chemical Resistance
Resists sweat, sebum, sunscreen and daily cleaners better than standard TPE and TPU.
UV / Weather Stability
UV-stable formulation for outdoor and sports use. Designed to resist yellowing.
Technical Data Available on Request
Easy-to-Clean Surface
Non-porous, low dust adhesion. Wipes clean without sticky residue or oil migration.
Injection Processing
Runs on standard thermoplastic presses. Fast cycles, regrindable scrap, no LSR dosing system.
SkinTouch Material Grades
Select by hardness, feel and bonding requirement. Detailed datasheets available per grade.

SkinTouch vs. Conventional Soft Materials
One consolidated comparison to support material evaluation. Qualitative guidance only -- contact engineering for application-specific testing.
| Property | SkinTouch Si-TPV | TPU | TPE | Silicone / LSR | PVC |
|---|---|---|---|---|---|
| Soft Touch | Silky velvet, dry | Firm, plastic-like | Soft but oily over time | Very soft, high friction | Soft, plasticizer dependent |
| Injection Molding | Standard press | Standard press | Standard press | Special LSR equipment | Standard press |
| Overmolding PC / ABS | Direct bonding | Good, edge peel risk | Application dependent | Requires primer | Application dependent |
| Surface Durability | No coating to peel | Good abrasion | Moderate | Tear sensitive | Moderate |
| UV / Weather | Stable, low yellowing | Yellowing risk | Application dependent | Good, stains easily | Stabilizer dependent |
| Recyclability | Thermoplastic regrindable | Recyclable | Recyclable | Not recyclable (thermoset) | Limited |
| Design Flexibility | Thin-wall + two-shot | Good | Good | Limited by tooling | Good |
How Is SkinTouch Processed?
Can you actually manufacture your product with SkinTouch? Yes -- on standard injection equipment with overmolding and two-shot capability.
