Poly Labs Injection Molded Thermoplastic Rubber (TPR) provide good slip resistance, tear properties, and overall durability. TPR Polymers are lightweight, resilient, as well as chemical and temperature resistant. TPR is often used in footwear products. Poly Labs offers a limitless range of color options with our injection molded thermoplastic rubber.
SBS Type TPR
Thermoplastic Rubber (TPR) compounds are formulated using Styrene-Butadiene-Styrene (SBS) block co-polymers. Poly Labs TPR 254 formulation offers advanced slip resistance with enhanced durability for footwear applications. For Injection Molded Thermoplastic Rubber 254 (TPR 254), the mechanical properties are as follows:
|Density||0.9 to 1.0 g/cm³|
