Ensinger PEI

ChenGuang CGF-218K PTFE Powder
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)
Material Notes: Molecular Formula: [CF2--CF2]n

CAS No. 9002-84-0

Description: In addition to all excellent properties of PTFE material, CGF-218 series powders has outstanding performance in paste extrusion to manufacture sealing tape, etc.. The resin are processed by mixing them with some organic solvents to obtain paste which are made into coherent, smooth and flat semifinished products after ram extrusion. During this progression the extruding pressure remains steady .The semifinished products can be further processed to produce unsintered tape by calendering, elongating and removing solvent with heat, and also to manufacture sintered coherent thin-walled tubing , continuous long rod, and wire & cable coating, etc.

Main Applications: Oil-free unsintered broad tape for cutting apart

Extrudate appearance: flat, smooth and coherent
