Product Details
Nitrile Rubber (NBR) insulation tubing is a flexible, closed-cell foam insulation material specially formulated from high-quality nitrile butadiene rubber and PVC compound. Featuring excellent thermal insulation performance, superior flexibility, high-density closed-cell structure and low thermal conductivity, this insulation tube is widely applied in HVAC systems, central air conditioning pipes, chilled water pipelines, refrigeration equipment, heating systems and industrial piping insulation. It effectively prevents heat loss, avoids condensation dripping, reduces energy consumption and protects pipelines from corrosion and external damage.
Key Features
Excellent Thermal Insulation: Low thermal conductivity effectively blocks heat transfer, achieving outstanding heat preservation and anti-condensation effects for cold and hot water pipes.
Closed-cell Waterproof Structure: High closed-cell rate provides superb water vapor resistance and low water absorption, preventing moisture penetration and ensuring long-term stable insulation performance.
High Flexibility & Easy Installation: Soft and bendable material fits various pipe shapes perfectly, easy to cut and install, saves construction time and labor cost.
Fire Retardant & Self-extinguishing: Compliant with international fire safety standards, self-extinguishing, low smoke and non-flammable, no droplet combustion during burning.
Durable & Anti-aging: Excellent resistance to aging, ozone, temperature change and chemical corrosion, long service life without easy deformation or cracking.
Eco-friendly & Safe: CFC-free, HCFC-free, asbestos-free and non-toxic, harmless to human body and environment, meets global environmental protection requirements.
Copper Pipe Friendly: Non-corrosive to copper, iron and aluminum pipes, effectively protecting pipeline systems.
3. Technical Advantages
The NBR insulation tubing maintains stable thermal performance under long-term high and low temperature conditions. Its superior water vapor diffusion resistance avoids insulation failure caused by moisture accumulation. The product features uniform foam density, smooth surface, stable dimensional tolerance and no hollow holes, ensuring consistent and reliable insulation effects in long-term use.
