Jiangmen foam factory tells you what foam plastic is?

　　Jiangmen Foam Factory tells you that foam plastics are polymeric materials formed by dispersing a large amount of gas micropores in solid plastics. They have characteristics such as lightness, heat insulation, sound absorption, and shock absorption, and their electrical properties are superior to gas resins. Their uses are very extensive. Almost all types of plastics can be made into foam plastics, and foaming has become an important area of plastic processing.

　　Jiangmen Foam Factory tells you, what is the definition of foam plastics? Let's take a look together. Also known as microporous plastics. Plastics with numerous interconnected or non-interconnected micropores throughout, resulting in a significantly reduced apparent density. They have advantages such as being lightweight, heat-insulating, sound-absorbing, shockproof, moisture-proof, and corrosion-resistant. According to the bubble structure, they can be divided into closed-cell, open-cell, and reticulated forms. In closed-cell foams, almost all the bubble pores are unconnected. In open-cell foams, almost all the bubble pores are connected. Foams with almost no foam cell walls are called reticulated foams. According to the density of foam plastics, they can be divided into low-foam, medium-foam, and high-foam foam plastics. A density greater than 0.4g/cm3 is considered low-foam, 0.1~0.4g/cm3 is medium-foam, and less than 0.1g/cm3 is high-foam. Jiangmen Foam Factory tells you that foam plastics are polymer materials based on plastics with a high foam content, so they can be considered composite plastics using gas as a filler. Compared with pure plastics, they have many excellent properties, including lightness, strength, impact absorption, heat insulation, and sound insulation. Therefore, they are widely used in industry, agriculture, construction, transportation, and other fields. Since their introduction to the market, foam plastics have been widely used and come in a wide variety of types. Common traditional foam plastics include polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), and phenolic resin (PF).

　　Jiangmen Foam Factory tells you that foam plastics can be divided into soft, hard, and semi-rigid foam plastics according to their flexibility. Hard foam materials can be used to make thermal insulation and sound insulation materials, insulation materials for pipes and containers, floating materials, shock-absorbing packaging materials, etc. Soft foam plastics are mainly used to make down-like materials, foam artificial leather, etc. Commonly used foam plastics include polyurethane, polystyrene, polyvinyl chloride, and polyethylene foam. With increasingly high performance requirements for foam plastics in special fields such as aerospace, traditional foam plastics cannot meet the special requirements of these fields in terms of material strength, stiffness, and heat resistance. Therefore, high-performance foam plastics have become a new direction and hot spot in foam research. High-performance foam plastics are already being used abroad in aerospace, space, and transportation. For example, the skeletons of satellite solar cells, the fairings at the front of rockets, the vertical tails of unmanned aerial vehicles, and the large radar domes of ships.
