Name: PVDF heat shrinkable tube, 175 ° heat shrinkable tube, polyvinylidene fluoride heat shrinkable tube, oil resistant heat shrinkable tube
Material: Dankai PVDF heat shrinkable tube is a copolymer of vinylidene fluoride homopolymer or vinylidene fluoride and a small amount of other fluorine-containing vinyl monomers. Dankai PVDF resin has both fluorine resin and universal tree
The characteristics of grease, in addition to good chemical resistance, high temperature resistance, oxidation resistance, weather resistance, radiation resistance, but also has piezoelectric, dielectric, pyroelectric and other characteristics.
Special performance, is currently the second largest product in the output of fluoroplastics.
Uses: Protection of electronic components in high temperature and oil environment: insulation and protection of resistance capacitors and thermocouples; Mechanical protection of various metal wires in Dankai; Wire terminal, connection and terminal
insulation, protection and reinforcement.
Protection of welding points, terminals and connecting lines from high temperatures, industrial fuels, solvents and chemical agents
Has good flame retardant properties and very low smoke value, extremely durable, wear resistance and resistance to mechanical damage
Especially suitable for adverse environments where corrosive air, thermal cycling, or mechanical stress may exist
Its semi-rigid, lightweight and chemical-resistant, heat-resistant, corrosion-resistant and UV-resistant properties are also used in automobiles, avionics, boats, fluid sensing, instrument wiring, public
Communication signal, communication and system control and other occasions.
