Rubber-plastic tubing is a composite pipe material featuring a closed-cell structure, manufactured through the blended foaming of rubber (NBR) and polyvinyl chloride (PVC). It is primarily utilized for thermal insulation on refrigeration units, chilled water pipes, condensate drains, and hot water lines within central air conditioning systems; its application scope also extends to piping projects involving cold and hot media across sectors such as construction, chemicals, pharmaceuticals, and shipbuilding. The product is suitable for temperatures ranging from -50°C to 110°C and possesses Class B1 or higher flame-retardant properties (Oxygen Index ≥ 32), a low thermal conductivity (not exceeding 0.034 W/m·K at 0°C), and excellent resistance to water vapor penetration (Moisture Resistance Factor μ ≥ 5000).
Produced via a closed-cell foaming process, this product features an elastic structure that requires no additional moisture barrier, allowing for direct installation in exposed environments. The material is free of CFCs and formaldehyde, complies with environmental protection standards, and offers combined resistance to corrosion, vibration, and noise [1]. Its high flexibility allows for installation via longitudinal cutting and bonding, or direct sleeving; this adaptability facilitates fitting around complex pipe bends and valves, and-even if removed after installation-the material remains reusable. With a flat, smooth surface (surface heat emission coefficient reaching 9 W/m²·K), it serves both insulation and aesthetic purposes, making it ideal for applications involving condensation prevention, thermal loss control, and architectural sound insulation.
Rubber-plastic insulation tubing features low thermal conductivity and a completely closed-cell structure, ensuring long-lasting and effective thermal insulation. The material forms a complete barrier against water vapor-preventing water absorption, resisting combustion, and eliminating condensation-thereby ensuring a long service life. Furthermore, SGS testing has confirmed that its measured values for toxic substance content fall significantly below the limits stipulated by EU standards, guaranteeing a healthy and safe environment for its use. Aesthetically pleasing with a soft exterior, the tubing is highly flexible, facilitating quick and convenient installation without the need for additional auxiliary materials.
