Description

CR or Chloroprene is a homopolymer of chloroprene or chlorobutadiene. NEOPRENE®.

Properties

• Excellent mechanical and abrasion properties even without reinforcing fillers
• Reasonable resilience in grades over 60º Shore A.
• Good resistance to heat, ozone and weathering.

• Flame retardant grades available.

• Good adhesion to metal.
• Temperature range: -13 F to +275 F.
• Resistance to chemicals; resistant to inorganic chemical products , except oxidising acids and halogens. Moderate resistance to aliphatic hydrocarbons.
