Product IntroductionHuaneng Hongyu Rubber and Plastic (NBR/PVC) is a flexible foam thermal insulation material containing a large number of small independent bubbles, which is made from NBR, PVC, etc., which are mainly made of NBR and PVC with excellent wear resistance, heat resistance and flame retardancy, added with foaming agent and anti-aging agent, after mixing and foaming. It has the characteristics of softness, resistance to bending, flame retardancy, low thermal conductivity, shock absorption, waterproofing, and sound absorption. It can be widely used for insulation of various cold and hot medium pipelines and containers in central air conditioning, construction, chemical, textile, metallurgy, shipbuilding, electrical and other fields, achieving excellent results in reducing cold and heat losses. It can also be processed and made into fitness equipment, daily necessities, and protective covers. Due to the advantages of clean and beautiful appearance, convenient construction, and no pollution, the rubber products produced by Langfang Huaneng Hongyu Rubber Products Co., Ltd. are known as the new generation of high-quality and environmentally friendly insulation materials in this century.Product FeaturesThe closed bubble structure can effectively prevent thermal conduction, and the thermal conductivity does not exceed 0.034W/m · k at 0 ° C.
- High surface heat release coefficient, reaching 9W/m2k
- It has excellent resistance to water vapor penetration and a moisture resistance of ≥ 5000, forming a "built-in" waterproof layer, making the insulation board both an insulation layer and a moisture-proof layer as a whole.
Fire resistance and aerobic index of 32 or above
- Easy and fast installation
- Free from CFC, HFC or HCFCs and other fluorinated materials, free from formaldehyde, dust and fibers
Product featureslow thermal conductivity
Huaneng Hongyu Rubber has an independent closed bubble structure, with countless tiny bubbles distributed inside. They are relatively independent and not connected to each other, ensuring the product's thermal insulation ability and reducing its thermal conductivity.
Waterproof and anti-corrosion performance
The formula of Huaneng Hongyu Rubber is unique, and scientific process technology is adopted in the production process, resulting in the internal distribution of small bubbles that are firmly connected and relatively independent, forming a rigorous closed bubble structure, achieving layer by layer barrier of water vapor molecules. Even if the material surface is damaged, it can prevent water vapor from penetrating into the interior. At the same time as waterproof and moisture-proof, it also plays a role in anti-corrosion for insulated pipelines, containers, etc. 
seismic performance

Huaneng Hongyu rubber insulation board has elasticity due to a large number of independent nostril bubbles, which can greatly reduce the vibration and resonance generated during the use of cold and hot water pipelines.

Easy installation and beautiful appearance
Huaneng Hongyu rubber insulation board is flexible and easy to construct. When insulating irregular components such as valves, tees, elbows, etc., the rubber sheet can be cut and tightly wrapped and bonded in different shapes to ensure that the insulation effect of the entire system is not affected. Due to the smooth and flat surface of rubber products, there is no need to add additional materials such as gas barriers or protective layers during installation, which not only reduces costs and saves time, but also facilitates construction and maintains the flatness and beauty of equipment and pipeline (component) appearance.
Flexibility performance
Huaneng Hongyu Rubber has good flexibility and toughness, making it easy to handle curved and irregular pipes (components) during construction, and can save labor and materials. When equipment or pipeline maintenance is carried out, the stripped rubber material can be reused without changing its flexibility and insulation performance.
green and environmentally friendly
Huaneng Hongyu Rubber does not contain harmful chlorine fluoride in the atmosphere and meets the ISO14000 international environmental certification requirements. It is very safe to use and will not irritate the skin or harm health. They can prevent mold growth, and are acid and alkali resistant, with superior performance.
Long service life
Huaneng Hongyu Rubber and Plastic has the characteristics of weather resistance, aging resistance, cold resistance, anti inflammation, heat resistance, drying resistance, moisture resistance, UV resistance, ozone resistance, 25 year aging resistance, deformation resistance, maintenance free service life, etc.
