Product catalog summary
Overview
CHOKS are electrical insulators that do not produce sparks due to friction with the ground, making them ideal for transporting dangerous goods. They are manufactured from EPDM and can be produced in various colors.
Composition
The primary components of CHOKS are ethylene and propylene.
Characteristics
EPDM rubber is known for its excellent resistance to water, ozone, steam, and UV rays. It maintains good flexibility at low temperatures and demonstrates significant durability against aging and weathering when used outdoors over the long term.
Properties
  • Composition: Ethylene, propylene
  • Color: Available in various colors or black
  • Specific Weight: 1.3 +/- 0.05 grams/cm3
  • Hardness: 65 +/- 5 Shore A
  • Breaking Load: Greater than 5 MPa
  • Elongation at Break: Greater than 300%
  • Tear Resistance: 20 N/mm
  • Minimum Service Temperature: -30°C
  • Maximum Service Temperature: 120°C
  • Hot Air Aging (72h at 70°C):
    • Increase in Hardness: 5 Shore A
    • Decrease in Breaking Load: -15%
    • Decrease in Elongation: -40%
