HAW-H22R hard rubber
HAW-H22R is a graphite filled hard rubber material based on HAW-22 (IR) which can be applied and vulcanized under pressure on site.
Description
HAW-H22R is a graphite filled hard rubber material based on HAW-22 (IR) which can be applied and vulcanized under pressure on site. The layer thickness of the rubber sheet may range between 3 and 6 mm. A particularly feature is its high diffusion resistance.
Range of application
- Protective lining for structural components made of steel that are subjected to chemical exposure
- The lining of flue gas scrubbers in refuse incineration plants, storage tanks and reaction vessels which are operated at temperatures up to 125°C.
Chemical resistance
Resistant
- alkaline and acid fluids with the exception of oxidizing fluids
Limited resistance
None listed
Not resistant
None listed
