Foamed plastic is a lightweight material formed by introducing a large number of tiny air bubbles into the plastic substrate. The basic principle is to use physical or chemical methods to form a large number of uniformly distributed pore structures inside the plastic during the molding process, thus significantly reducing the density of the material and improving thermal and acoustic insulation and other properties.
Features of foamed plastic
- Lightweight: Foamed plastics contain a large number of internal pores, the density is significantly reduced, usually only a fraction of ordinary plastics or even lower. This lightweight feature makes it has a significant advantage in the field of transportation, packaging and so on. 2.
- Thermal insulation: The pore structure of foamed plastics can effectively block the heat transfer, so it has excellent thermal insulation properties.
- Cushioning and impact resistance: Foamed plastic has good elasticity and cushioning properties, which can absorb and disperse external impacts and protect the contents from damage. This feature makes it an ideal packaging material.
- Sound insulation: the pore structure inside the styrofoam can also effectively absorb sound waves and reduce sound transmission, so it is often used as sound insulation materials.
- Low cost: The raw materials for the production of foamed plastics come from a wide range of sources, and the production process is relatively simple and low-cost, making it suitable for large-scale industrialized production.
Application of foamed plastic
- Packaging: Because of its light weight, cushioning and impact resistance, styrofoam is widely used in the packaging of electronic products, home appliances, food, pharmaceuticals and other products. 2.
- Construction: Foamed plastics are widely used in the construction field because of their heat insulation and sound insulation properties.
- Transportation field: the light weight and strength of Foamed Plastic make it used in automobiles, ships, aviation and other means of transportation:
- Household products: Foamed plastics are also widely used in daily household products:
- Cold chain logistics: the heat insulation property of styrofoam makes it an important material for cold chain logistics:
- industrial field: foamed plastic is also widely used in industrial field:
- Other fields: in the medical field, Foamed Plastic can be used for the packaging and protection of medical devices; sports equipment, used to make helmet liners, knee pads and other protective equipment.
