Good heat resistance, chemical stability, high tensile strength,low shrinkage, excellent abrasion resistance characteristics.

PTFE filaments are fiber-based, can be processed into various types of high-performance mesh,fabric, sewing thread, dental floss, membrane structures,and other products.


New in our range of PTFE products: PTFE filament yarns made out of pure, virgin PTFE filament. This PTFE filament yarn has good heat resistance, a high tensile strength and is chemically resistant. 
Additionally it offers low elongation and excellent abrasion resistance characteristics. PTFE filament can be processed into types of high-performance mesh, fabric, sewing thread, dental floss, membrane structure and other products. Thicknesses from 200D to 1200D.


PTFE YARN



For braided PTFE filament packing. 


The Teflon wire is extruded from high-quality tetrafluoroethylene powder and processed into a film through a series of procedures, and is formed into a line by stretching or the like. Teflon wire is a premium material used in the sealing industry for braided packing. Type: Pure PTFE line (oil-free white PTFE line) Silicone oil PTFE line (oily white PTFE line) Graphite PTFE line (oily black PTFE line).


It has high density and flexibility, good self-lubricity, excellent chemical resistance, low friction coefficient and no pollution. It meets the requirements of the food industry and has good stability to strong corrosive media such as acid, alkali and solvent. It can be used for corrosion. The sealing of the pump and valve is especially suitable for industries with hygienic requirements. Application: Universal valve packing for valves and low speed running equipment such as centrifugal pumps and reciprocating pumps, mixers, etc.

The Teflon wire is a wire made of PTFE, commonly known as fluoroplastic, and wrapped with a metal conductor. Because Teflon has: non-tackiness, heat resistance, slidability, moisture resistance, wear resistance, corrosion resistance and other characteristics. Therefore, Teflon wire has better thermal stability and mechanical wear resistance than other high temperature wires. It can resist strong acid and alkali, corrosion resistance, refractory and non-combustible, high oxygen index, low smoke and no halogen, no aging, easy to strip. High strength and friction resistance. The temperature resistance of the Teflon wire is different from that of the material of the outer casing. There are roughly three types of PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 ° C, with the highest operating temperature of 290-300 ° C, very low friction coefficient, good wear resistance and excellent chemical stability Sex. FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film. It has excellent chemical stability and excellent non-stick properties. The maximum operating temperature is 200 °C. PFA: PFA (perfluoroalkylate) non-stick coating, like FEP, melts and flows during baking to form a non-porous film. The advantage of PFA is that it has a higher continuous use temperature of 260 ° C and stronger toughness. It is especially suitable for use in the field of anti-adhesion and chemical resistance under high temperature conditions.

For braided PTFE packing.
