What is CR?
“CR” stands for Chloroprene Rubber, which is a synthetic rubber material often referred to by its trade name “Neoprene.” Neoprene is known for its unique combination of properties, making it suitable for a wide range of applications across various industries, including automotive, marine, sports and leisure, construction, industrial, and more.
CR exhibits good resistance to ozone, oxygen, sunlight, alkalis and acids. Neoprene has good flame retardant properties. It provides good tensile strength, elasticity and moderate oil and gasoline resistance. The table show the common NR properties below.
|Hardness (Shore A)||40 – 90|
|Tensile Strength (MPa)||Good|
|Elongation at Break (%)||Good|
|Tear Strength (N/mm)||Good|
|Temperature Range (°C)||-40 to 120|
|Adhesion to Metals||Good|
|UV and Weather Resistance||Good|
