- Provides effective insulation in large temperature range environments ranging from -50 to 110 degrees C.
- Very low thermal conductivity properties result in excellent insulation for AC ducts, Chilled water pipelines, copper pipelines, drain pipelines, etc.
- Very high water vapor diffusion resistance properties resulting in negligible water absorption.
- Class O provides top notch fire performance as per the building regulations.
- Non-reactive and offers excellent resistance to chemicals, oil, and ozone.
- Zero Ozone depletion properties.
- It is dust and fiber free product.
Flexible elastomeric closed-cell foam pipe insulation, also known as rubber, is composed of synthetic rubber. The two main foam rubber formulations that are commercially available are nitrile butadiene rubber with PVC (NBR/PVC). The insulation materials are widely in multiple scenes for thermal insulation and noise reduction, which are used in various pipes and equipment, such as central air conditioning, air conditioning units, construction, chemical, medicine, electrical appliances, aerospace, auto industry, thermal power etc.
