Flexible NBR/PVC Rubber Foam Thermal Insulation Pipe Tubing

Our Flexible NBR/PVC Rubber Foam Thermal Insulation Pipe Tubing (also referred to as elastomeric nitrile rubber foam pipe) is engineered for high-performance thermal insulation and condensation control. Featuring a dense, self-contained closed-cell structure, this insulation material acts as a natural integrated vapor barrier that effectively blocks water vapor penetration to prevent pipe sweating, rust, and corrosion.

Remaining remarkably supple from ultra-low to medium-high temperatures, it wraps smoothly and neatly around elbows, tees, valves, and irregular fittings without cracking.

• Core Advantages:

• Superior Thermal Insulation: Low thermal conductivity effectively curbs heat transfer, slashing energy usage for air conditioning, refrigeration, and hot water piping systems.

• High Moisture Resistance: High vapor diffusion resistance and negligible water absorption ensure long-lasting, stable insulation performance.

• Flame Retardant & Low Smoke: Self-extinguishes without burning drips; low smoke output complies with stringent international building fire codes.

• Noise & Vibration Reduction: Effectively suppresses pipeline flow noise and mechanical vibration, making it ideal for soundproofing projects.

• Eco-Safe Formula: 100% CFC/HCFC-free, zero ODP, low GWP, fibre-free, anti-mold, low VOC, and fully RoHS & REACH certified.

• Effortless Installation: Lightweight, highly bendable, and available with optional self-adhesive or aluminum foil surfaces. Seal joints easily with matching adhesive glue for total airtight coverage.

  
  

Main Applications:

• HVAC central air conditioning copper tubes, chilled and hot water distribution lines

• Refrigerant piping for commercial freezers and cold storage facilities

• Industrial chemical fluid pipelines and marine plumbing systems

• Solar hot water pipes and fire protection water pipelines

• Insulation shielding for electrical cables and automotive hydraulic tubes

  
  

  

FAQ

• Q1: Is this NBR/PVC foam pipe tubing UV resistant for outdoor use?

• A: Standard NBR/PVC foam has limited direct UV resistance. For outdoor applications, we strongly recommend choosing our aluminum foil-faced NBR/PVC insulation tubing or applying a protective anti-UV coating to ensure maximum lifespan under sunlight.

• Q2: What are the differences between Class 0 and Class 1 flame-retardant grades?

• A: Class 0 offers higher fire performance (meeting British Standard BS 476 Part 6 & 7), exhibiting lower smoke emission and superior self-extinguishing behavior, making it mandatory for high-rise commercial buildings and public HVAC projects.

• Q3: Can you provide free samples for testing?

• A: Yes! We offer free standard product samples for quality evaluation. Clients only need to cover the express shipping cost. Contact us today to request your sample kit.

• Q4: What is your Minimum Order Quantity (MOQ)?

• A: For standard sizes, our MOQ is flexible (typically 1,000 meters or 1 pallet). For customized sizes or special foil/adhesive coatings, MOQ details can be negotiated with our sales team.
