Lubrizol EstaGrip ST80A TPE

The EstaGrip ST80A thermoplastic polyurethane series features rubber-like properties.
ST80 was specifically developed by Lubrizol Corporation USA for Fluke Corporation USA. It has a Shore hardness of 80A, an orange-yellow color, and as a polyether product, it offers superior elasticity, abrasion resistance, excellent chemical and heat resistance. It is suitable for heavy-duty applications such as overmolded casings for electronic test tools, industrial tool handles, and durable leisure applications like skateboard wheels.
Key Advantages of ST80A
*Good adhesion to various plastics;
—Estane TPU/Estaloc REPT/traditional TPU/thermosetting PU;
—ABS, CAB, COPE, Nylon-11/12, some PA-6/6, and vinyl;
—No need for adhesives or mechanical locking;
—Excellent adhesion to wood, metal, or polyolefin substrates via bonding layers or mechanical locking.
*Ergonomically friendly/easy-to-grip surface;
*Outstanding soft touch, a market leader;
*Exceptional durability and toughness, unmatched by other TPE products;
