Lixin Packaging - Performance of Styrofoam

Compared with pure plastic, foam plastic has low density, light weight and high specific strength. Its strength increases with the increase of density, it has the ability to absorb impact load, it has excellent cushioning and shock absorption performance, sound insulation and sound absorption performance, thermal conductivity. Low, good thermal insulation, excellent electrical insulation, corrosion resistance, mold resistance. Flexible foams have excellent elastic properties.

The use of Dongguan styrofoam

Structural foams developed in the 1960s are characterized by foaming of the core layer and non-foaming of the skin layer. The internal hard toughness of the outer layer is higher than the strength (strength per unit mass), and the material consumption is reduced. Wood is increasingly widely used as a substitute for wood. Used in the construction and furniture industry. The success of chemical or radiation cross-linked foaming of polyolefins has resulted in a significant increase in the production of foam. The foams obtained by blending, filling, reinforcing and other modified plastics have better comprehensive performance and can meet the needs of various special applications. For example, glass fiber-reinforced polyurethane foams produced by reaction injection molding have been used as structural components for aircrafts, automobiles, computers, etc.; and foams filled with hollow glass beads filled with polybenzimidazole have light weight and high temperature resistance. It has been used in spacecraft.
