based on XPS extruded board, composite functional materials developed by the new structural materials and functional materials, the current product in the domestic market is almost blank
size: 1/2'', 1/4'' etc or can be customized
1,Thermal insulation performance:
At present, the market of indoor insulation materials are basically divided into two types: EPS system and XPS insulation system. Comparison of the two XPS better than the EPS insulation effect, EPS is 0.041, XPS is 0.030 so that the same effect under the premise of XPS than EPS can do thinner, lighter weight. But the two kinds of insulation materials for the time being did not in-depth development for the finished product building materials or not formed, the market and more pure plate between the surface and the interior as an insulation layer to use.
As the structural material bearing capacity is particularly important, here is the strength of pure sheet tensile strength, polystyrene board bulk density and tensile strength have an absolute relationship between the general EPS capacity 18Kg / m3 tensile strength of 110 ~ 120KPa, 20Kg / M3 capacity of about 140KPa or so. XPS bulk density from 25Kg ~ 45Kg, the intensity from 150KPa ~ 700KPa or higher. (Provided that the thermal conductivity is about 0.03). It can be seen, as a general structural materials, finished XPS multi-functional backing plate enough to meet the requirements of home improvement and tooling.
3, Waterproof performance:
As a functional material, Sanyi multi-functional backing plate waterproof performance is particularly advantageous. Whether it is used as structural material or functional material, Sanyi multi-functional sheet has good waterproof performance and anti-seepage ability, XPS pure plate with high thermal resistance, low linearity, low expansion ratio characteristics, the structure of the closed-cell rate More than 99% of the formation of a vacuum layer, to avoid air flow cooling, to ensure its insulation performance of the lasting and stable, relative to the foam polyurethane 80% of the closed-hole rate, the leading advantage is self-evident. Practice proved 20mm thick XPS extruded insulation board, the insulation effect is equivalent to 50mm thick foam polystyrene, 120mm thick cement perlite. Can be directly as a ground waterproof layer, to warm insulation layer, facade insulation layer, processed into products after its waterproof performance is more stable, multi-functional waterproof floor as a multi-functional backing plate extension products more market potential!
