HAW-H22 hard rubber
HAW-H22 is a graphite filled hard rubber material based on isoprene rubber (IR) that is vulcanized in an autoclave.
Description
HAW-H22 is a graphite filled hard rubber material based on isoprene rubber (IR) that is vulcanized in an autoclave. 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 reaction and process tanks, especially tube bundle heat exchanger and lining of stainless steel which are operated at temperatures up to 130°C.
Chemical resistance
Resistant
- alkaline and acid fluids with parts of organic solvents
Limited resistance
None listed
Not resistant
None listed
