Rubber & Plastic Insulation Pipe

1. Product Material

Rubber & plastic insulation pipe is a flexible cylindrical black insulation pipe made of NBR-PVC (nitrile butadiene rubber + polyvinyl chloride) as base material, mixed with flame retardant, foaming agent and anti-aging additives. It is produced by internal mixing, extrusion and closed-cell foaming shaping. It belongs to flexible foam rubber-plastic thermal insulation products, complying with national standard GB/T17794-2021.

2. Core Technical Performance

Thermal conductivity ≤0.034 W/(m·K), excellent energy-saving effect for heat and cold preservation

Operating temperature: -40℃～105℃, suitable for both cold and hot pipelines

Closed-cell rate ≥95%, high water vapor transmission resistance. It has an inherent moisture and vapor barrier, effectively preventing condensation dripping without extra waterproof covering

Fire performance: mainstream Class B1 flame retardant for engineering use (self-extinguishing, low smoke, no dripping); Class B2 combustible grade for simple household models, in accordance with GB8624-2012

Zero fluorine, formaldehyde-free and dust-free. Soft and highly elastic, with built-in vibration damping and sound absorption performance. Acid & alkali resistant and mildew-proof for long service life

3. Specifications & Classification

Standard length: 2 m per piece

Inner diameter: full range 6–114 mm (sleeve directly for small pipes; rubber-plastic sheet wrapping for pipes over 114 mm)

Wall thickness: 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm (custom available)

Types:

Plain closed rubber-plastic pipe: sleeved onto pipelines before installation

Self-adhesive split rubber-plastic pipe: for renovation of existing pipes, no pipe removal required, stick directly after peeling off backing

Aluminum foil faced rubber-plastic pipe: for outdoor exposed pipelines, UV and aging resistant

4. Product Advantages

Closed-cell waterproof structure thoroughly solves condensation dripping of air-conditioning water pipes and ceiling mildew.

Flexible material, easy to cut and fit tightly on elbows, tees and valves for convenient installation.

Flame retardant & low smoke, easy to pass fire inspection for commercial buildings.

Built-in sound absorption and vibration reduction to reduce noise from water flow and units.

Corrosion and aging resistant, stable for long-term use in cold storage and humid basements.

Lightweight and dust-free construction, applicable for clean workshops, hospitals and shopping malls.

5. Application Scenarios

Central air conditioning system: cold water & cooling water pipes for anti-condensation

Plumbing & HVAC: heat preservation for hot water and heating pipes, freeze protection for outdoor water pipes in winter

Supporting pipelines for solar, air source and heat pump units

Industrial equipment: thermal insulation, cold preservation and noise reduction for process pipes in chemical plants, storage tanks and cold chain machine rooms
