Summary: The thermal guidance rate of ordinary plastic products is ...
The thermal guidance rate of ordinary plastic products is mostly 0.15 ~ 0.22W/(m, K), while the thermal guidance rate of core material foam plastic is generally within the range of 0.01 ~ 0.04W/(m. K), which is better than ordinary plastic. The product is as low as 15 to 50 times and has excellent thermal insulation performance. The resin, which is commonly used as the heating foam products, has hard PU, PF, meritorodehyde and PS. Use at high temperatures. Pay attention to the heat -resistant temperature of different varieties when selecting specific selection.
PS and PVC should be selected at low temperature, and PU and PF should be used at high temperature. The thermal insulation of the crisisythyde foam plastic is very good, and it has the advantages of flame retardant, low price and wide source. However, due to its large brittleness and serious water absorption, it affects widespread application. It can be widely used for building insulation, reducing house heat loss by 70%. Core foam plastic has excellent sound insulation performance, and is becoming more and more important in the field of sound insulation.
The specific application of sound insulation foam plastics is specifically used in wall decoration materials and ceiling materials such as cinema, theater, and singing halls. It uses foam plastic sound -absorbing with good sound insulation performance to prevent the sound and affect sound quality. In the interval wall of the building house, it is made of foam material and has a sound insulation effect. The commonly used sound insulation is made of foam plastic materials, including PU soft foam plastic materials, PS beads, PVC (lotion), PF and PE, etc.





Core foam plastic products are a very good shock absorption material. It can be used as packaging materials, such as packaging materials for fragile products, home appliances and precision instruments. The foam plastic materials that can be used for shock -proof are EPS, PE, soft and semi -soft PU. Most of the high -foam -foaming core foam plastic has better reflection, and some varieties also have high reflection, which can be used for sports equipment, soles, sofas, and cushions. There are two types of foam plastics with high -return elasticity, and are commonly used in soft PU foam plastics.
Using lightweight and closure, floating materials require that the relative density of foam plastics must be small, and it must be a closed foam plastic with double foam. The resin that can be used for floating foam plastics mainly include PVC. PE and PS. For open -hole microporous foam plastics, it has the characteristics of liquid and can be used as filtering materials, water absorption materials and flower and trees transplantation materials.
The specific available resins include F4, acetate cellulose, nitrate cellulose, PA, PVC and PP, etc. Most of the core materials foam plastics have the advantages of soft and firm, which can be used as a shoulder pad material for clothing. The specific available is PE and PU soft foam plastic.
