High-quality NBR insulation foam tube for HVAC, refrigeration, and plumbing. Closed-cell structure, anti-condensation, flexible, and fire-retardant. Ideal for pipe freeze protection and energy saving.

Key Features

• Superior Thermal Performance – Low thermal conductivity minimizes heat gain/loss, improving system energy efficiency.

• Moisture & Condensation Resistance – Closed-cell structure prevents water vapor penetration, eliminating the need for additional vapor barriers.

• High Flame Retardancy – Meets various international flame retardant standards (e.g., UL94 V-0, BS 476), limiting flame spread.

• Flexible & Easy to Install – Soft and resilient, the tube can be directly slipped over pipes or slit along the seam for wrapping without complex tools.

• Aging & Chemical Resistance – Excellent resistance to oils, ozone, UV radiation, and many chemicals, ensuring durability in various environments.

Typical Applications

• Insulation for air conditioner copper pipes and chilled water lines

• Thermal insulation for hot water pipes and water heaters

• Automotive air conditioning and industrial refrigeration systems

• Freeze protection for solar water heating pipes

• Pipe acoustic insulation and thermal control in marine and railway applications
