Nbr Sponge Foam Tape Suitable For A Wide Temperature Range
-- Steady & Reliable Manufacturer --
Detailed Product Description
NBR (Nitrile Butadiene Rubber) sponge foam tape is a closed-cell elastomeric insulation material known for its excellent flexibility, exceptional resistance to oils and fuels, and stable thermal performance across a broad temperature range. NBR foam is particularly effective in low-temperature HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) applications due to its very low thermal conductivity (λ), which minimizes heat gain and prevents condensation (sweating) on cold surfaces.
The highly flexible, fine-celled structure ensures a tight, continuous seal even when wrapped around irregular shapes or pipes, maintaining its elasticity without cracking or hardening at sub-zero temperatures (down to −50∘C). The tape is typically backed with a modified synthetic rubber or acrylic adhesive, chosen for its strong initial bond and ability to remain flexible and secure within the specified operational temperature extremes of the refrigeration or cooling system.
Why Choose Us
Advantages and Core Features
- High Thermal Efficiency: The low thermal conductivity (λ) of the closed-cell NBR foam provides a superior insulation barrier, effectively reducing energy consumption in cooling systems and preventing surface condensation (sweating) in cold applications.
- Oil and Hydrocarbon Resistance: NBR's nitrile content makes it highly resistant to degradation from contact with lubricants, oils, greases, and fuels, ensuring its integrity in mechanical and engine environments where other foams would fail.
- Wide and Stable Operating Range: Maintains flexibility and does not become brittle at extreme cold (down to −50∘C) or degrade significantly at continuous high temperatures (up to +105∘C).
- Odor-Free Formulation: Unlike some rubber-based materials, NBR is engineered to be low-odor, making it suitable for interior appliance use and human-occupied spaces (e.g., residential HVAC).
- Fungus and Bacteria Resistance: The material is resistant to mold and mildew growth, making it a hygienic choice for applications in damp or internal cooling systems (HVAC coils).

Frequently Asked Questions
Frequently Asked Questions (FAQs)
- Q: Why is NBR foam preferred for refrigeration pipes over standard foam?
- A: NBR is preferred due to its superior moisture-sealing capability and low thermal conductivity, which are critical for preventing condensation formation on cold lines, thereby mitigating corrosion and insulation degradation.
- Q: Can NBR tape be used to dampen noise?
- A: Yes, the dense, elastic nature of the closed-cell sponge provides good acoustic dampening properties, making it effective at isolating vibration and reducing structure-borne noise in mechanical assemblies.
- Q: Is the adhesive affected by the low temperatures?
- A: We use specific cold-weather modified adhesives designed to maintain their flexibility and bond strength even at sub-zero temperatures, ensuring the tape does not lift or peel during cold operation.
- Q: Does NBR foam contain halogens or other harmful substances?
- A: Our standard NBR formulations are RoHS and REACH compliant, and we can provide specific halogen-free grades for applications requiring strict material compliance.
