Our NBR/PVC Rubber Foam Insulation Tube is a high-performance elastomeric insulation solution engineered for B2B HVAC, plumbing and industrial piping projects. Produced by Zhongjia, a leading insulation material manufacturer in Guangdong, China, this custom black insulation tube is made from premium nitrile butadiene rubber (NBR) and polyvinyl chloride (PVC) via advanced closed-cell foaming technology. Classified as B1 Grade Fireproof Insulation Tube, it delivers exceptional thermal insulation, moisture resistance and acoustic damping, with a wide operating temperature range of -40°C to +120°C. Lightweight, flexible and easy to handle, it effectively reduces heat loss, prevents condensation and cuts energy costs for commercial, residential and industrial piping systems, fully complying with international insulation and fire safety standards. As a professional B2B product, it is the first choice for large-scale piping insulation projects requiring long-term durability and stable performance.
The closed-cell structure of the insulation tube blocks heat transfer between pipelines and the external environment, with a thermal conductivity as low as ≤0.032 W/(m·K) at -20°C. It minimizes heat loss in hot fluid pipelines and heat gain in cold systems, maintaining stable medium temperatures and slashing energy consumption for piping projects.
Formulated with high-quality fire-retardant additives, the tube reaches Class B1 fire-proof level with an oxygen index ≥32%. It features self-extinguishing properties when exposed to open flames, restricts fire spread and reduces toxic smoke release, ensuring safety for high-rise buildings and industrial workshops.
With a water vapor permeability coefficient ≤2.8×10-11 g/(m·s·pa) and vacuum water absorption ≤5%, it prevents water vapor and liquid water penetration. It protects the underlying pipes from humidity-induced corrosion and maintains performance in high-humidity environments like basements and coastal areas.
Made of flexible polymer materials, the tube can be easily bent to fit complex piping layouts (elbows, tees) without special cutting tools. It can be quickly fixed with adhesive tape or clamps, shortening construction cycles and reducing labor costs for B2B construction teams.
The dense cellular structure absorbs pipeline vibration and fluid flow noise, acting as a sound barrier to reduce noise transmission. It is ideal for noise-sensitive projects such as hospitals, hotels and residential buildings, enhancing indoor comfort.

Applied in central air conditioning refrigerant pipelines and ventilation ductwork, it prevents condensation and cold loss, stabilizing system operation and protecting building structures from water damage.
Suitable for pipelines transporting hot oil, steam and chilled water in workshops, it resists harsh industrial environments and protects pipes from external damage.
Used for household hot water pipes and floor heating systems, it retains water temperature, reduces heating costs and lowers pipeline vibration noise for indoor living spaces.
Ideal for malls, hospitals and office buildings, it meets strict fire safety and noise reduction requirements, aligning with green building standards for sustainable operations.
Applied in cold storage pipelines and refrigerated transport vehicles, it blocks external heat infiltration, prevents pipe frosting and ensures refrigeration efficiency.
We offer comprehensive customization for NBR/PVC Rubber Foam Insulation Tube to meet diverse B2B project needs: customizable length (any size beyond 1.82m), inner diameter DN15~DN300and thickness (5mm-50mm). We also provide OEM/ODM services, including custom brand printing, packaging design and special material formula adjustment for specific working conditions. Small and large batch custom orders are all supported with fast production lead times.
For B2B clients, we provide a 1-year official warranty for all insulation tube products, covering material and manufacturing defects. Our 7×24 online technical support team offers professional solutions for installation, construction and on-site application problems, with dedicated engineers available for on-site guidance for large-scale projects. We also provide timely logistics tracking for bulk orders and a fast response mechanism for quality issues—any non-human damage within the warranty period will be resolved with replacement or repair at no cost. Long-term B2B cooperative clients enjoy exclusive technical consulting and product upgrade notifications.
