This image has an empty alt attribute; its file name is CYG-FKM-300x261.jpg

CYG-FKM is very flexible at both high and low temperatures without cracking. Made from modified fluoroelastomer, CB-FKM is used for applications at elevated temperatures and has superior chemical and solvent resistance properties. It reliably protects wire, solder joints, terminals, connectors and components from most industrial fluids, solvents and chemicals.

Standard: SAE-AMS-DTL-23053/13

Material:
Irradiation cross linked modified fluoro elastomer
Shrink ratio: 2: 1

Features:

  • temperature, flame retardant, oil, acid, soft;
  • Operating temperature: -40 ℃ ~ 200 ℃;
  • shrink temperature: 175 ℃;
  • Standard color: black.

Application: high temperature environment of electronic components to protect the oil, resistance of the capacitor, thermocouple insulation and protection, mechanicalprotection of all kinds of metal wire and the like, wire end splice, insulated terminals, protection and reinforcement.
