产品描述
IROGRAN A95K 4640 is a caprolactone-based thermoplastic polyurethane. The material has been developed for injection molding applications requiring exceptional performance in terms of compression set, wear resistance and hydrolysis resistance over conventional polyester-based TPUs.
IROGRAN A95K 4640 is part of the High Performance Injection Molding product range and offers a specially designed, flexible material suitable for the production of seals, wheels and rollers, coupling halfs and o-rings.
PERFORMANCE FEATURES
High wear resistance
Low compression set
Short cycle times
Excellent hydrolysis resistance
Resistant to high dynamic loads
