Guangdong PTFE Heat Shrink Tubing Manufacturer

PTFE heat shrink tubing is made from imported polytetrafluoroethylene (commonly known as Teflon or the king of plastics) resin, processed through special methods. Huayuanxin products have advantages such as high temperature resistance, high pressure resistance, corrosion resistance, wear resistance, and good self-lubricating properties. They are widely used in various fields such as machinery, electronics, automotive, aerospace, chemical industry, and communications. Features: 1. High and low temperature resistance, continuous use temperature (-80~260℃) 2. Corrosion resistance (resistant to strong acids, strong bases, chemical reagents, and oils) 3. Shrinkage temperature ≥300℃, shrinkage ratios 2:1, 4:1 Standard color: Transparent, can be made in black.
