HAW-W12 soft rubber
HAW-W12 is a soft rubber based on chlorosulfonated polyethylene (CSM), that is vulcanized in an autoclave.
Description
HAW-W12 is a soft rubber based on chlorosulfonated polyethylene (CSM), that is vulcanized in an autoclave. The layer thickness of the rubber sheet may range between 3 and 6 mm.
Range of application
- Protective lining for structural components made of steel that are subjected to exposure acids and another oxidizing, aqueous media
- The lining of process, storage- and transportation tanks, which are exposed to oxidizing stress and operated at temperatures up to 80°C (e.g. sodium hypochlorite or hydrochloric acid, sodium hydroxide solution, chlorine bleaching solution etc.).
- Especially the lining of transportation tanks for varying freights, too.
Chemical resistance
Resistant
- alkaline and acidic media
- oxidizing acids (with exceptions)
Limited resistance
- organic acids (with exceptions)
- solvents and greases
Not resistant
None listed
As listed on the data sheet. A medium not listed is untested, not unsuitable. Ask us about your exact medium and concentration.
