CYG-PTFE Heat Shrink Tubing

Category: Special Design Heat Shrink Tubing

Product manual

Material:
     Irradiation crosslinked modified polytetrafluoroethylene material
Shrink ratio: 2: 1
Features:
  • high temperature, translucent, flame retardant, semi-rigid;
  • Operating temperature: -55 ℃ ~ 260 ℃;
  • Minimum shrink temperature: 327 ℃;
Applications: PTFE heat shrinkable tube is coated on the chemical components may have anti-oil, acid, corrosion resistance. Coated on the electrical components may have excellent resistance to high temperature resistance and electrical insulation. Coated printing and dyeing, paper, printing, chemical and other industries roll may have lubrication, non-sticky material. Coated repeated movement of the mechanical parts, obtain low friction coefficient, smooth operation, to avoid the "catch-line," etc., it is widely used in electrical, mechanical, printing ah, petrochemical and other industries.
