Teflon® PTFE 8

产品说明

Teflon® PTFE 8 is a free-flowing white powder composed of relatively large particles. Its most unique features are high bulk density and excellent powder flow.

The high bulk density and low compression ratio of Teflon® PTFE 8 permit the use of shallow molds for small parts and complex shapes. Good powder flow is necessary for use in equipment that feeds resin automatically.

Teflon® PTFE 8 is used for general-purpose, highspeed automatic preforming of small parts and ram extrusion of large diameter rod and tubing. Properly processed products made from neat Teflon® PTFE 8 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. Molded products have moderate stiffness and high ultimate elongation.

In a flame situation, products of Teflon® PTFE 8 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.
