Polystyrene insulation plastic sheet is also known as EPS board, is mainly used for building exterior wall heat preservation and heat insulation, cold storage, air conditioning, vehicle ship system, changshu da plastic products factory to smoothly and everyone here to introduce the advantages and disadvantages of polystyrene insulation plastic board.
polystyrene PVC foam insulation board advantages:
1. Light: provisions in China standard USES the bulk density is 18 ~ 22 kg/m3 of EPS board, Europe with 15 kg/m3 of EPS board only;
2. Low thermal conductivity, due to its full of air mass of pore structure to prevent the spread of air, make its coefficient of thermal conductivity in 0. 039;
3. Due to its board in 98% of the space is filled with air, have enough ability by changing the shape and reply to the external impact cushioning, good impact resistance;
4. Low water imbibition: studies have shown that the humidity will affect the material's thermal properties and mechanical properties, material of low water imbibition helps to keep the performance;
5. Recycling use: its recycling degree is the highest of plastic;
6. In the production process does not apply to freon;
7. The whole life cycle energy consumption of the lowest in the plastic products.
polystyrene foam insulation board faults:
1. Need to hang a net long, complicated construction and time.
2. Flammable, toxic, ordinary polystyrene foam insulation board easy to burn, toxic smoke, even after adding flame retardant combustibility also can only achieve B. External wall insulation fire polystyrene foam insulation board accounted for 95%.
3. Material strength is poor, prone to cracking phenomenon, insulation layer falls off phenomenon is common.
4. Polystyrene foam insulation board due to the limited its own strength, bearing ability is poor, when facing brick to strengthen processing.
5. Polystyrene foam insulation board quality is not stable, because materials need to be placed before the factory may only be used for a period of time after a period of maturity, if not cure thoroughly quality will not be guaranteed results in foam board shrinkage cracking.
