CR or Chloroprene is a homo-polymer of chloroprene or chloro-butadiene. It has excellent mechanical and good abrasion properties even without reinforcing filters and has a reasonable resilience in grades over 60° shore A.
It displays good resistance to heat, ozone and weathering and also gives good adhesion to metal. The recommended operating temperature range is between -40°C to +125°C. It has good resistance to inorganic hydrocarbons.
