Thermoplastic Polyester Elastomer (TPE)
High Performance TPE
EY Technologies constructs its extrusion coated braid harness yarns with high tenacity, synthetic multifilament core yarns. The tensile properties of the extrusion coated core yarn are essentially unaffected by temperatures up to 300° F (150° C). The extrusion coated braid yarns are tolerant to most engine fluids to which a braided harness may be exposed.
High Performance TPE
High Performance TPE (Thermoplastic Polyester Elastomer) coated polyester yarn is designed for applications that require outstanding abrasion resistance with improved heat and chemical resistance.
