PTFE Sewing Thread is made of PTFE Filament Fiber. Polytetrafluoroethylen, PTFE in short, is commonly known as King of Plastic in China. It has macromolecular linear structure and almost no branch chain. The molecular chain is hard to destroy for the carbon atoms on the main chain are protected by the stable chemical C-F both sides of macromolecule. So the PTFE material has good heat resistance and anti-corrosion.
With the dipole moment of PTFE macromolecule closing to zero and basically no polar, it has good insulation property. PTFE macromolecule has low surface free energy, high non-adhesion and lowest friction coefficient. The melting point of the crystalline state for high molecular material is 327 centidegree, so the material can be used within the temperature range of -195 centidegree~+260 centidegree for a long time. Non-breaking or non-burning, PTFE has a LOI of 95.
Tensile Strength:>=4.2g/den or 38CN/Tex
Heat Resistance:-190~260 centidegree
Length per kg:7200m
