[0002] PTFE split filament refers to the use of polytetrafluoroethylene (PTFE) film as raw material, through a special processing technology, the film is decomposed into a fibrous material with a certain length and diameter. This kind of split filament usually has excellent high temperature resistance, corrosion resistance and non-stick properties, and can be used in textiles, fillings, sealing materials and other fields.
[0003] In the preparation process of PTFE film split filaments, raw material mixing is a very important link. When preparing PTFE film split filaments, PTFE resin powder is mixed with other additives (such as lubricants, reinforcing agents, etc.).
