CR
Chloroprene rubber
CR is a chloroprene based synthetic elastomer. The material has good wear properties and weather resistance. Due to its chlorine content, CR is flame-retardant.
Areas of application:
- Conveyor belts in outdoor areas
- Window sealing profiles
- Seals for refrigeration systems
- V-belts
