Elastomeric rubber‑plastic insulation tubes are manufactured from modified NBR‑PVC copolymer via vacuum micro‑crystal closed‑cell foaming, specially designed for HVAC piping systems. Featuring high elasticity, they resist cracking under repeated bending, with good tear‑resistance and compression resistance, avoiding flattening on complex pipeline layouts. Complying with GB 8624‑B1 flame‑retardant grade, low‑smoke and halogen‑free for building fire‑safety standards. Excellent ozone‑aging and UV resistance, outstanding moisture & vapor barrier performance to prevent condensation, low shrinkage and cracking risk for long‑term indoor and outdoor service. Fine uniform closed‑cell structure delivers low thermal conductivity for stable heat insulation, together with noise‑damping function. Integral color customization available in red, blue, black and more colors, helping installers identify high/low‑pressure refrigerant pipes. Formaldehyde‑free and free of toxic volatiles, safe for residential indoor applications.

Application Scope 

Household split air‑conditioners, commercial multi‑split units, central air‑conditioning, refrigeration equipment, HVAC pipeline thermal insulation and noise reduction.
