Vulcanizates of CSM are highly resistant to the deteriorating effects of ozone, oxygen, weather, heat, oil and chemicals. CSM resists discoloration on exposure to light, and is widely used in light- colored vulcanizates. It can be compounded to give excellent mechanical properties—for example, high tensile strength and abrasion resistance.

CSM is used in the rubber industry because of its wide range of unique properties. The properties may be summarized as:

• Permanent bright colors
• Superb ozone and weather resistance, even in non-black products
• Heat resistance to 150°C
• Resistance to a wide range of aggressive chemicals
• Intermediate oil and solvent resistance depending on the chlorine level
• Electrical insulating properties
• Low flammability characteristics (associated with chlorinated polymers)
• Excellent resistance to abrasion and mechanical abuse
