When the density of the polystyrene foam board is insufficient, if it is used for external insulation of the building exterior wall, it will lead to low tensile strength, which cannot meet the load-bearing requirements of the thermal insulation system and the load on the shear strength of the decorative load, and it is easy to make the middle of the EPS board. It is broken; at the same time, the insufficient density of the EPS board will also lead to a decrease in heat insulation performance and an increase in moisture absorption, which will affect the building's heat insulation effect. The polystyrene foam board will not play the role of energy saving and heat preservation in the building.


At present, there are about 2,000 production enterprises in China, and the production of polystyrene foam plastics has a good momentum and the quality has been continuously improved. But the number of large enterprises is small. It is reported that the apparent density refers to the mass of a unit volume of foamed plastic under specified temperature and relative humidity conditions. Apparent density affects other physical performance indicators to a certain extent and directly reflects the cost of the product.


Foam boxes produced by foam box manufacturers , EPS packaging products are widely used in household appliances, power tools, instruments, liquid crystal displays, aquatic seafood, edible fungi, fruit and vegetable products, vaccine reagents, hardware lighting, crafts, glass, ceramics, export furniture products Packaging, with good cushioning, impact resistance and heat preservation and refrigeration effects. In the future, the company sincerely looks forward to cooperating with powerful and reputable electrical appliance manufacturers, printing and packaging companies, real estate developers and contractors, insulation box wholesalers, and friends from all walks of life dedicated to packaging and energy-saving insulation, to create a better future. Make new contributions to the country's energy-saving insulation.
