CR (neoprene, chloroprene rubber, bayprene)

Neoprene is a synthetic rubber, obtained by polymerization of chlorobutadiene. Its most significant characteristics are great tensile strength, high resistance to hydrolysis and moderate resistance to petroleum oil, oxygen, ozone, UV radiation, salt and aging. Besides that it is non-flammable and does not swell in mineral oils.

Unlike many other materials, it has excellent sealing properties. Due to its low compression strength, it is well resistant to abrasion and cracking if flexed. It also binds perfectly with metals.

Usage:

gaskets, seals for cooling devices, roller coverings, hoses, insulation of cables, springs, conveyor belts.

Advantages:

• moderate resistance to mineral oils,
• good resistance to ozone, oxygen, UV, salt, wear,
• excellent resistance to freon and ammonia,
• great tensile strength.

Disadvantages:

• moderate water resistance,
• poor resistance to solvents.

Temperature resistance: from – 35 °C to 100 °C.

Hardness: 25 to 90 Shore A.
