It is widely used in important scientific and technological industries such as electronics, computers, electrothermal, aerospace, military, communications, etc. It is commonly used in hydraulic pipelines and their joint parts to protect pipelines from corrosion. Due to its very high mechanical strength and extremely low coefficient of friction, it is the preferred protective product for protecting stressed shafts and shaft related products.
Teflon heat shrinkable pipe is made of imported high-quality polytetrafluoroethylene (commonly known as plastic king) resin and processed by special methods. This product has the advantages of high temperature resistance, high pressure resistance, corrosion resistance, wear resistance, and good mechanical strength. It is widely used in various fields such as machinery, electronic chemistry, communication, etc.
