Foam board, independent of its internal honeycomb structure enclosed bubble, is a high compressive strength, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, super anti-aging (long-term use almost no aging), low thermal conductivity, excellent thermal insulation properties of environmentally friendly materials.
Extruded panels are widely used in dry wall insulation, flat concrete roof and steel roof insulation, low temperature storage on the ground, low-temperature floor heating pipes under the auxiliary radio heating, parking platforms, airport runways, highways and other areas of moisture-proof insulation, control ground frost, is the construction affordable, quality is superb insulation, moisture-proof material. VRD decorative composite insulation board insulation materials currently in use is extruded polystyrene board (xps board), will also be launched simultaneously with polyurethane, phenolic and a series of composite structure as the VRD thermal insulation composite decorative boards, widely used in wall insulation, flat concrete roof and steel roof insulation; for low temperature storage on the ground, parking platforms, airport runways, highways and other areas of moisture-proof insulation. Excellent, long-lasting thermal insulation of the lower thermal conductivity as possible is the goal of all insulation materials. Extruded polystyrene board mainly made from raw materials, and polystyrene is an excellent low thermal conductivity of the original material, supplemented by extrusion extrusion, cellular structure is even more closely and effectively prevent heat transfer, thermal conductivity shaped plate coefficient of 0.028 / m. k, with high thermal resistance, low linear expansion characteristics.
Thermal conductivity is much lower than other insulation materials. Such as the EPS board, polyurethane foam, insulation mortar, perlite, etc. Superior resistance to water, moisture extruded closed-cell structure with close board, polystyrene molecular structure itself does not absorb water, positive and negative plates are no gaps, so the very low water absorption, excellent moisture and anti-permeability. Corrosion, durability general rigid foam insulation is easy to use after a few years of aging, along with resulting performance degradation caused by water. The extruded plate for excellent anti-corrosion, aging resistance, heat resistance, high water vapor pressure, can maintain its excellent performance, service life of up to 30-40 years.
