Product name: 25mm rubber-plastic insulation board Product specification: complete product category: rubber and rubber products/rubber products origin: Beijing price: 700/ cubic remarks: rubber-plastic sponge I. Product introduction Hengxing brand rubber-plastic sponge insulation material is made by introducing the latest foreign technology and advanced automatic continuous production line, using nitrile rubber and polyvinyl chloride (NBR, PVC) with excellent performance as main raw materials and various high-quality auxiliary materials, and foaming by special process. This product is a closed-cell elastic material with excellent properties such as softness, buckling resistance, cold resistance, heat resistance, flame retardant, waterproof, low thermal conductivity, shock absorption and sound absorption. It can be widely used in various cold and hot medium pipes and containers in central air conditioning, construction, chemical industry, medicine, textile, metallurgy, ships, vehicles, electrical appliances and other industries and departments, and can achieve the effect of reducing cold loss and heat loss. Because of its convenient construction, neat and beautiful appearance and no pollution, it is a new generation of high-quality thermal insulation materials across the century. Because of its flexibility and bending resistance, this material can be processed into handles and sheaths for fitness equipment, medical instruments and daily necessities. Second, the thermal conductivity is low. When the average temperature is℃, the thermal conductivity of this material is 0.034 W/MK, and its surface heat release coefficient is high. Therefore, under the same external conditions, the same thermal insulation effect can be achieved if the thickness of this product is more than half that of other thermal insulation materials, thus saving the space above the ceiling of the floor and saving the investment. 3. Good flame retardancy This material contains a lot of flame retardant and smoke reducing raw materials. The concentration of smoke produced during combustion is extremely low, which will not melt in case of fire, and will not drop the burning fireball. This material has the property of self-extinguishing. According to GB8624- 1997 "Classification Method for Combustion Performance of Building Materials", this product is a B 1 grade flame retardant material to ensure safety and reliability. Convenient installation and beautiful appearance. Because this product is flexible, the installation is simple and convenient. Pipeline installation, you can put it on and install it together, or you can cut this pipe longitudinally and stick it together. Used for complex parts, such as valves, tees, elbows, etc. The board can be cut and wrapped into different shapes to ensure the tightness of the whole system, thus ensuring the heat insulation of the whole system. Because of the smoothness and excellent performance of rubber, there is no need to add another layer of gas barrier and protective layer, which reduces the trouble in construction and ensures the beautiful and flat appearance. When the equipment or pipeline is overhauled, the stripped material can be reused with the same performance. Fourth, seismic characteristics Hengxing brand rubber and plastic insulation material has high elasticity, so it can minimize the vibration and * * * vibration of chilled water and hot water pipes during use. V. Other Advantages Hengxing brand rubber and plastic insulation materials are very safe to use, which will neither irritate the skin nor endanger health. They can prevent the growth of mold, avoid the bite of pests or mice, and are acid and alkali resistant with excellent performance. These characteristics make Hengxing brand rubber and plastic become an ideal insulation material to protect pipelines and prevent them from being corroded by atmospheric media or industrial environment. 6. Hot water pipes are used in indoor and outdoor hot water pipe systems such as hospitals, hotels, houses and factories. And choose Hengxing brand rubber and plastic insulation materials, which can effectively reduce its heat loss. In addition, Hengxing brand rubber and plastic has been proved to be the most ideal insulation material for indoor and outdoor pipes of solar heating system.
