Write main specialities of Buna-S, Neoprene rubber?
Advertisements
उत्तर
- Buna-S:
It has mechanical strength and has abrasion resistance. Hence, it is used in tyre industry. - Neoprene:
- Neoprene is particularly resistant to petroleum, vegetable oils, light as well as heat.
- Hence, it is used in making hose pipes for the transport of gasoline and making gaskets.
- It is used for manufacturing insulator cable, jackets, belts for power transmission and conveying.
