Kolon KOPEL® KP3372 General Purpose TPE Resin
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Elastomer, Melt-Processible Rubber
Material Notes:	KOPEL® is a thermoplastic polyester elastomer which is a new engineering rubber having combined properties of conventional rubber and thermoplastic. Its flexibility and elastic recovery are very similar to rubber, but its processability is much superior to rubber. While its flexibility and elastic recovery are similar to rubber, its mechanical properties-heat resistance, weather resistance and UV stability-are far greater than the performance of rubber. Excellent flexibility and creep resistance, good mechanical properties and heat stability, good chemical resistance Information provided by US distributor, API-Kolon.
