Chemours Tefzel™ ETFE HT-2195 Premium-grade fluoroplastic resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; ETFE/ECTFE; Fluorocarbon ETFE/ECTFE, Molded/Extruded
Material Notes:	Tefzel™ ETFE HT-2195 is a premium-grade fluoroplastic resin designed for use in rotational molding. To be effective as a rotational molding resin, Tefzel™ ETFE HT-2195 is a free-flowing powder with controlled particle size, shape, and size distribution. Applications: Tefzel™ ETFE HT-2195 is ideal for many end products for fluid handling in chemical processing industries, including pump housings, vessels, columns, elbows, tees, and pipe sections with unusual shapes. In addition, any hollow structure with internal contours that permits uniform coating by powder flow is a candidate for lining, provided it can withstand high temperatures.
