PTFE Compound

Overview of fluoroplastic (PTFE) compound

High functionality compound material Fluoroplastic compound

Using fluoroplastic as base, we propose compound material with fillers according to your application.

Fluoroplastic compound molded products demonstrate excellent chemical resistance, thermal resistance, electrical properties and remarkably low coefficient of friction. However, for imparting more mechanical strength according to the application, they are used after mixing with various fillers.

According to your desired properties, we will present the most appropriate types of filler and blending amount.

Types and features of fillers

We offer the following varieties of fillers according to diverse applications.

Filler	Features and size	Expected functions
Glass fiber	Milled fiber of grain diameter 10-15μm	Wear resistance
Carbon	Amorphous carbon of grain diameter 75μm or below	Wear resistance, cold flow resistance, compression characteristics
Graphite	Crystalline carbon of grain diameter 40-50μm	Sliding characteristics, water resistance
Bronze	Spherical powder of grain diameter 40μm or below	Cold flow resistance, hardness, compression characteristics
Molybdenum disulfide	Spherical powder of grain diameter 40μm or below	Lubricating property, sliding characteristics
Carbon fiber	Filled fiber of diameter 8-10μm	Cold flow resistance, compression characteristic, electrical conductivity
Various engineering plastics	PPS, PEEK, Econol, polyimide, etc.	Cold flow resistance, compression characteristics, passive against sliding material
