Noveon ESTAGRIP® ST 70A Ether-Type Thermoplastic Elastomer
Subcategory: Elastomer, TPE; Thermoplastic
Material Notes:
Description: This patented technology was developed specifically for the most demanding overmolding applications providing unprecedented adhesion capability to a variety of substrates, the most comfortable soft touch in the industry, and unparalleled durability. The EstaGrip® TPE technology inherently has a higher COF (Coefficient of Friction) and is therefore more grippy; by designing the mold surface finish accordingly the designer can even further enhance this grippy feel. The unique chemistry results in a very warm, soft, comfortable “feel” that translates to the impression of about a 10 hardness point reduction on the Shore scale; i.e., the ST70A, a measured 70 Shore A product, feels like a 60 Shore A product.Major Benefits of EstaGrip® TPEs: - Excellent adhesion to a variety of plastic substrates
- Estane® TPU / Estaloc® RETP / traditional TPUs / thermoset PU
- ABS, PC, PC/ABS, PET, PBT, CAB, COPE, PA-11/12, some PA-6/6, and vinyls
- No adhesive nor mechanical interlocks required
- Good adhesion to wood, metal, or polyolefin substrates with either adhesive layer or mechanical interlocks
- Ergonomically friendly / inherently grippy surface
- Uncompromised Soft Touch - like nothing else available in the marketplace
- Outstanding durability and toughness unmatched by other TPEs
- Rubber-like performance similar to that of more expensive COPAs
- Easily pigmentable
- ST80A has formal UL 94 HB certification for all colors
- Faster cycling than similar hardness TPEs
