Teflon® PTFE 9B
聚四氟乙烯
DuPont Fluoropolymers

产品说明

Teflon PTFE 9B is a free-flowing white powder composed of premelted resin. It is designed for use in the ram extrusion process. Compared with other DuPont resins suitable for ram extrusion, Teflon® PTFE 9B provides outstanding resistance to charge fracture (poker-chipping) caused by excessive back-pressure during the extrusion of small-diameter rods, thin-wall tubing, and complicated profiles. Its uniform particle characteristics make it well suited for difficult feeding conditions.

Properly processed products made from neat Teflon® PTFE 9B provide the superior properties typical of the fluoropolymer resins: retention of properties after service at 260°C (500°F), useful properties at -240°C (-400°F), chemical inertness to nearly all industrial chemicals and solvents, and low friction and antistick surfaces. Dielectric properties are outstanding and stable with frequency and temperature.

In a flame situation, products of Teflon® PTFE 9B resist ignition and do not themselves promote flame spread. When ignited by flame from other sources, their contribution of heat is small and with very little smoke.

Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions.
