Chloroprene rubber

Description

Chloroprene rubber is a high-performance synthetic rubber, which has many superior characteristics compared to natural and even other synthetic rubber types, so it has a wide diversity of applications. Our company can provide a wide range of grades such as General types, Adhesive application types and Special types to match different application.

Characteristics

Chloroprene rubber demonstrates a good balance of features, including such as resistance to ozone, oil and heat; flame retardancy, weatherability, special cohesiveness, etc., and is very easy to process, and it has excellent properties with remarkable durability under severe condition such as:

Weather and ozone resistance;

Oil resistance;

Abrasion resistance;

Flame resistance;

Aging and heat resistance;

Excellent adhesion properties.

Application

• Electrical wiring and cables
• Automotive components
• Belts, hoses
• Coated cloth, foam rubber
• General industrial articles
• Adhesives, etc.
