Rubber roll
What is a rubber roll?
Generally, it is cylindrical form coated with rubber elasticity externally and is a roll to be able to unroll rubber material combined for each purpose of application.
Rubber materials
- Natural rubber ・・・ (NR)
- Synthetic rubber ・・・ (SBR, similar in composition to natural rubber)
- Chloroprene rubber・・・ (CR)
- Nitrile rubber ・・・ (NBR)
- Butyl rubber ・・・ (IIR)
- Ethylene-propylene rubber ・・・ (EPT)
- Hypalon rubber ・・・ (CSM)
- Fluoro rubber ・・・ (F)
- Silicon rubber ・・・ (Si)
- Urethane rubber ・・・ (U) etc.
Application
Various uses for conveying, chemical resistance, acid resistance, heat resistance, pressure resistance, abrasion resistance, nonadhesion resistance, antistatic, ozone resistance, solvent resistance, and for lubrication
