4 Series

TOPESTER® 4 Series, Copolyester Thermoplastic Elastomers (TPCs) provides processors and designers with cost competitive copolyester thermoplastic elastomers (TPCs). This series is used in a variety of  injection molding, extrusion, and blow molding applications.

TPCs are known for their exceptional toughness and flexibility. High impact strength in combination with low temperature resilience, moisture/gas permeability, flexural fatigue/chemical/heat resistance make them excellent candidates for Automotive, Industrial Hoses and Tubing, Transportation, Furniture, Sports & Leisure, Breathable Films/Wearables, and Building & Construction applications.
