PVDFHeat Shrink Tubing Guangzhou Puzhong Brand
Material:PVDFShrink tubing is a copolymer of偏fu ethylene or偏fu ethylene with a small amount of other乙烯基 monomers.PVDFResin combines the properties of both fluorinated and general resins. In addition to its excellent resistance to chemical corrosion, high temperature, oxidation, weathering, and radiation, it also possesses special properties such as piezoelectricity, dielectricity, and thermoelectricity. It is a leading product in terms of production volume among fluorinated plastics.
Application: Protection of electronic components in high-temperature, oily environments: resistors, capacitors, thermal couples, insulation and protection; mechanical protection for various metal wire types; insulation, protection, and reinforcement of wire ends, joints, and terminals.
Features: High temperature resistance, thermal insulation, media resistance, transparency, rigid.
Shrinkage Temperature:175℃Above shrinkage: radial shrinkage≥50% Axial shrinkage rate≤10%,Operating Temperature:-55℃～175℃
Standard Color: Transparent,Reference Standard:MIL-I-81765（AS） z9-0753-91
