Changyi bubble foam board manufacturers, the cold plate Changyi foam insulation board, eps insulation board, where you can find what you want standard foam board. Before using foam board to be detected note: 1, the dimensional change: the dimensional variation in the material will result in cracking of the surface layer of the system. 2, water vapor permeability coefficient: The performance determines the performance of the water vapor permeability to some extent determines the wall condensation. 3, thermal conductivity: this specification is a key indicator of the relationship in general engineering laboratory testing insulation effect applied is dried to constant weight of the test material in the plate and is used under certain conditions of moisture contained in the air The use must therefore be multiplied by a coefficient; or directly adjust the material to the environment under the conditions tested. 4, the oxygen index: the need to fire retardant or not compliance. 5, dry density: the apparent density of the material to a certain extent, affect the apparent density of the thermal conductivity substandard materials will directly lead to decreased physical properties such as strength and dimensional stability. 6, compressive strength: foam plates that the compressive stress at 10% of the specimen deformation. It is related to durability and impact resistance of the surface layer of the system. Zhucheng Changyi foam material _ Hua Yong foam (certified) _ Changyi bubble by Zhucheng Yong foam factory.
