Diesel Resistant Heat Shrinkable Elastome CYG-DR

Material: Specialty elastomers
Shrink ratio: 2:1

Features:

  • high temperature resistance, flame resistance, chemical resistance;
  • Soft, oil, especially diesel oil;
  • Operating temperature: -65 ℃ ~ 150 ℃, shrink temperature: 175 ℃;
  • Meets MIL-DTL-23053/16.

Application: widely used in aviation, aerospace, military wire harness coat, and automotive wiring harness a wide operating temperature range, while the requirements for diesel, aviation fuel, hydraulic oil, lubricants and other fluids have better tolerance to environmental .

CYG-DR is a modified cross-linked flexible elastomer, and is widely use the wire harness protection of automotive, aviation, aerospace, military, which have the requirement of the resistance to diesel fuels, hydraulic fluids and lubricating oil.
