TPR – Thermo Plastic Rubber
Thermoplastic elastomers (TPE) are a combination of polymers (usually a plastic and a rubber) which consist of both thermoplastic and elastomeric properties resulting in a product that is extremely easy to use in manufacturing a variety of products. TPEs require little or no compounding and no need to add reinforcing agents, stabilizers or cure systems.
Applications: Automotive Fluid Delivery Systems, Household appliances, Sporting goods, Electrical and Medical components.
