rubber-plastic board are nitrile rubber , polyvinyl chloride , etc. It is a special material widely used in various types of pipeline insulation. It is mainly used for water pipes and air ducts in central air-conditioning systems, insulation projects for buildings, ships, vehicle refrigeration equipment, hot water pipes and process pipes. It is also widely used in sports equipment sheaths, gaskets and life-saving diving suits. After a special foaming process, a dense foamed air chamber is formed inside, which can effectively block energy dissipation. It has a soft texture, thermal conductivity ≤0.033w/m.k, moisture resistance factor ≥7500, flame-retardant material, operating temperature -40~105 °C, the fire protection level is level 0, level B1 and level B2.
According to the requirements of " Fire Protection Design Code for Buildings " and "Fire Protection Design Code for High-Rise Civil Buildings", the insulation materials used for pipelines and equipment must be non-combustible or refractory. According to GB8624-2006 "Combustion Performance Classification of Building Materials and Products", the international standard for products in the field of building products with combustion performance not lower than Class C. rubber plastic contains a large amount of flame-retardant and smoke-reducing raw materials. The smoke concentration generated when burned is extremely low, and it will not melt when exposed to fire and will not drop fireballs, ensuring safety and reliability. In addition to fire protection level, grade 0 rubber and plastic has excellent thermal insulation performance and moisture barrier performance. However, the price of grade 0 rubber-plastic panels is higher than other grades, so it is currently mainly used in laboratories, food factories, or public places with higher fire protection requirements.
Grade 0 rubber-plastic panels have low thermal conductivity, gray appearance, completely closed-cell structure, and long-lasting and good thermal insulation effect. The material is completely isolated from water vapor, has a long service life, does not absorb water, and does not condense. After SGS testing, its measured value is far lower than the standard value of and EU for non-toxic substances. It is healthy and safe to use, and its appearance is soft, beautiful, and easy to bend. , construction is convenient and fast, and no other auxiliary materials are needed. The independent closed bubble structure of Utesin rubber and plastic can form multiple barriers to water vapor molecules. Even if the surface of the material is damaged, it can prevent water vapor from penetrating into the interior of the material, thus maintaining the long-term stability of the product's thermal insulation effect.
