B1 Closed-Cell Rubber Insulation Pipe Manufacturer | Jinsimai Xiaolong – Energy-Saving Thermal Insulation for HVAC Systems Worldwide
Introduction
People need insulation materials for HVAC and industrial hot and cold pipes all over the world. Buyers care more about three points: water resistance, fast installation, and low long-term running cost. More people accept green, low-carbon building ideas. Many construction teams stop using old fiber insulation. This old material soaks up water easily and makes dust when workers cut it. Flexible closed-cell rubber plastic insulation becomes the most popular material now.
Xiaolong B1 grade flexible rubber plastic insulation belongs to Tianjin JinSimai Building Materials Technology Co., Ltd. It has a full closed-cell foam structure. Factories, hotels, office buildings, and shopping malls around the world use it to wrap HVAC pipes. It works better than rock wool and glass wool. We sell complete pipe sleeves and flat sheets. They fit home central air pipes, commercial air conditioning, and industrial hot and cold circulation pipes.
Core Technology Solves Common Industry Problems
We mix high-purity nitrile rubber and PVC, then use a one-step foam process to make Xiaolong rubber plastic pipe and sheet. Every small cell stays closed and separate. The material takes in far less water than rock wool and glass wool. It stops water vapor from passing through. This fixes two common problems: water drops on air conditioning pipes and rust on metal pipes.
Workers can lay this product in wet underground pipe tunnels, outdoor heating pipes, and seaside areas with heavy salt fog for many years. Its heat preservation ability will not drop. Pipes and insulation layers can be used much longer.


Fast Installation & Lower Total Cost
This rubber plastic material is soft. Workers can cut it to any size. It fits elbows, valves, and tees tightly. People do not need extra auxiliary materials or separate waterproof layers.
If workers use rock wool or glass wool, wrapping one pipe takes more time. Xiaolong material cuts construction time by nearly 30%. No fiber dust floats during cutting and installation. It meets global construction safety and environmental rules. After wrapping, the surface forms a smooth, sealed cover. People spend little money on later maintenance. HVAC projects save labor and auxiliary material costs. The whole life cost of the project goes down clearly.
Global Certificates & Stable Supply
All Xiaolong rubber plastic insulation gets mainstream global certificates, such as EU CE and Russia GOST. We send large goods to many countries and areas. Tianjin JinSimai runs full-automatic production machines. We can supply standard pipe sleeves, flat sheets, and custom rolls in large quantities all year. We also make goods with special thickness and size for non-standard pipes and equipment.
Every performance data of our products follows the ISO global standards and the local fire safety rules of different countries. We give full flexible energy-saving pipe insulation plans for global HVAC construction companies and building material dealers.
Future Plan
Our firm keeps adding more overseas technical staff. We build online and offline service channels with multi-language support. We make new rubber plastic insulation that can stand harsh weather. It fits hot, freezing, wet, and seaside salt fog areas. We will keep providing good HVAC pipe insulation materials for global green buildings and industrial energy-saving upgrade projects. We help the construction industry cut energy use and reach power saving goals.
