HAW-H94 hard rubber
HAW-H94 is a graphite filled hard rubber material based on isoprene/styrene-butadiene rubber (IR/SBR) that may also be applied on site and vulcanized using hot water or steam.
Description
HAW-H94 is a graphite filled hard rubber material based on isoprene/styrene-butadiene rubber (IR/SBR) that may also be applied on site and vulcanized using hot water or steam. 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 chemical exposure
- The lining of flue gas scrubbers in waste incineration plants, storage tanks and reaction vessels which are operated at high temperatures.
Chemical resistance
Resistant
- alkaline and acid fluids with the exceptions of oxidizing fluids
Limited resistance
None listed
Not resistant
None listed
