By a large number of gas pores dispersed in a solid plastic and polymer materials to form a kind of cold plate design, with light, heat, sound, vibration and other characteristics of cold plate sales, and dielectric properties superior to the matrix resin, use it wide. Almost all kinds can be made of plastic foam, foam molding plastic processing has become an important area. Before using the foam board to be detected note: 1, the dimensional change: the dimensional variation in a material will lead to cracking of the surface layer of the system. 2, water vapor permeability coefficient: The performance determines the performance of water vapor through the wall to some extent determines whether condensation. 3, thermal conductivity: This specification is a key indicator of general laboratory tests insulation effect relationship engineering applications is dried to constant weight of the test material in the plate which is used under certain conditions of humidity contained in the air The use must therefore be multiplied by a coefficient; or directly to adjust the material to the environment under the test conditions. 4. Oxygen Index: Otherwise fire retardant need not be reached. 5, dry density: the apparent density of the material to some extent, affect the apparent density of the thermal conductivity of the material will directly lead to failure of the physical properties such as strength and dimensional stability decrease. 6, compressive strength: Foam sheet refers to the compressive stress at 10% specimen deformation. It is related to the durability and impact resistance of the surface layer of the system.
