Tri-Metallic (TEFLON PURPOSE)

Teflon is an artificially synthesized high polymer material that replaced all hydrogen atoms in polyethylene with fluorine. This material has the characteristics of resistance to acid and alkaline and various kinds of organic solvents; it is virtually insoluble to all solvents. At the same time, polytetrafluoroethylene (PTFE) is also resistant to high temperatures with extremely low friction coefficient. Thus, in addition to acting as a lubricant, it is also an ideal coating for non-stick pans and inner layers of pipes.

However, due to the high molding temperature of Teflon and its tendency to release highly corrosive gases under a high-temperature environment, it will cause corrosion to the barrel within a short time. Therefore, Tan Star is actively researching Teflon purpose tri-metallic barrels; the high percentage of nickel content allows the barrel to have superior anti-corrosion capabilities, effectively resistive to the acidic gases produced by Teflon.

The Tri-Metallic Barrel for Teflon Purpose is specifically designed to address the unique challenges associated with PTFE processing. Compared with conventional barrels, its specialized construction provides enhanced resistance to corrosive gases generated during high-temperature molding, helping maintain barrel integrity and processing stability over extended production periods. This makes it an ideal solution for manufacturers seeking improved reliability when processing fluoropolymer materials.

Leveraging extensive experience in bimetallic and tri-metallic barrel technology, TAN STAR INDUSTRIES INC. combines advanced centrifugal casting expertise with carefully selected alloy materials to create barrels capable of operating in highly demanding environments. The result is a durable processing solution that helps reduce maintenance requirements, extend equipment service life, and support consistent product quality in PTFE extrusion and molding applications.
