HAW-H90 hard rubber
HAW-H90 is a graphite filled hard rubber material based on isoprene rubber (IR) that is vulcanized in an autoclave.
Description
HAW-H90 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.
Range of application
- Protective lining for structural components made of steel that are subjected to chemical exposure
- The lining of reaction and process tanks and pipe spools that are operated at high temperature ranges, max. 100°C (depending on the service conditions).
Chemical resistance
Resistant
- alkaline and acid fluids with the exceptions of oxidizing fluids
- aliphatic hydrocarbons (with exceptions) and alcohol
Limited resistance
- aromatics
