Product Description

Haiflon® PTFE Fine Powder Resin SF-628

Description :
In addition to all excellent properties of PTFE material, SF-628 powders has outstanding performance in paste extrusion to manufacture sealing tape, etc.. The resin is processed by mixing them with some organic solvents to obtain paste which are made into coherent, smooth and flat semi-finished products after ram extrusion. During this progression the extruding pressure remains steady .The semi-finished 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..

Application:          
Make medium and high density seal tape, tube, rod, elastic band, belt, various length of Fiber.
