Closed cell foam with a high closed cell ratio significantly improves the water vapor isolation ability. It is highly resistant to condensation and offers excellent moisture resistance to ensure the long-term insulation effect.
Nitrile rubber foam insulation material adopts an advanced closed cell foam process. This structure gives it unique water vapor resistance, low thermal conductivity, and sound insulation & shock absorption properties. It is widely applicable to water pipes and ducts in HVAC systems, refrigeration and heating equipment, hot water piping, and process pipelines for cold insulation, ensuring the tightness of the entire system.
