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

Applications:

  • Interior Automotive Components
  • Overmolded Wire & Cable components
  • Hand-Held / Power Tools
  • Sporting Goods
  • Athletic Footwear
  • Medical Devices
  • Hand-Held Electrical/Electronic Devices
  • Industrial Components

    Specific Notes for this Material: Outstanding unique comfortable feel, unprecedented adhesion to a variety of substrates, superior durability, and rubber-like resilience
