Product description

Description

There are two kinds of PTFE rods to offer. One is manufactured by Paste extruding method in the diameter from 4 to 9mm and the other Is made by ram extruding method is the diameter from 10to 50mm; rods Over the diameter 50mm are manufactured by molding. PTFE is the most chemical-resistant of all known plastics. It does not age.

PTFE has a wide range of practicable temperature from 180%°C - +260°C and a wax-like surface to which anything hardly sticks.

PTFE has the lowest coefficient of friction of all known solid materials. It has the best electrical properties of all plastics.

Filled material: 

Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2,  glass bead, polyamide.
