Co-extrusion Line For PVC Foam Corrugated Sheet PVC co-extruded foam insulation sound insulation tile The latest composite co-extrusion technology is used to produce a new generation of PVC sound insulation tiles. The surface layer can be made of weather-resistant PVC modified material or ASA raw material, the core layer has a foam density of 0.35-0.55g / cm3, super durable, heat preservation, environmental protection and energy saving, asbestos-free, good heat insulation, acid and alkali corrosion resistance, economical, The colorful and durable features are the choice of new-generation factory buildings (especially electroplating plants, chemical plant buildings for tile replacement), warehouses, real estate, aisles, roofs, carports and other engineering roofing building materials. 1) Excellent thermal insulation performance and stable chemical properties. The upper and lower layers are modified upvc, and the middle layer is a polymer foam layer. UPVC insulation tiles and the use of core foaming technology ensure that a porous structure is formed inside the product to effectively block the transmission of heat insulation energy. The thermal conductivity of the insulation tile is 0.219W / mk, which is about 1/3 of the earthen tile, 1/5 of the 10mm thick cement tile, and 1/2000 of the 0.5mm thick colored steel tile. 2) The core layer of the three-layer foam insulation tile is a porous material with porous ventilation properties. When the sound of falling rain strikes the tile surface, the sound waves are transmitted to the porous material, causing air vibration in the gap and friction with the porous wall.
