Product Information
Outline
Chloroprene rubber has many superior characteristics compared to natural and even other synthetic rubber types, so it has numerous applications. In particular, its possible uses have been expanded to civil engineering/construction and precision components as well. Our company meets such needs by providing a wide range of grades such as special denatured types, and latex best suited to making aqueous adhesives, etc.
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.
Uses
- Electrical wiring and cables
- Automotive components
- Belts, hoses
- Coated cloth, foam rubber
- General industrial articles
- Adhesives, etc.
