The resins that can be used for floating foam are mainly PVC, PE and PS. The resins commonly used as thermal insulation foam products include rigid PU, There are several kinds of PF, urea-formaldehyde and PS. In sound insulation Aspect: The core material foam has excellent sound insulation properties and is increasingly important in the field of sound insulation applications.

Used as a shoulder pad material for clothing. The specific available resins are F4, cellulose acetate, nitrocellulose, PA, PVC and PP, etc. 4. Now it can be widely used in building heat insulation, reducing the heat loss of the house by 70%.22W/(m, K), while the thermal conductivity of foam The conductivity is generally in the range of 0. There are two types of foam with high resilience: PU and PE, and soft PU foam is the most commonly used.

Utilize high resilience: Most foams with high foaming ratio have good resilience, and some varieties also have high resilience, which can be used for sports equipment PMI foam , Shoe soles, sofas and cushions, etc. In terms of shock resistance: foam plastic products are a good shock absorption material, which can be used as high-end packaging materials, such as packaging materials for fragile products, household appliances and precision instruments.04W/(m.15～0. 2.

Core material foam, core material foam manufacturer Method for air-coupled ultrasonic detection of PMI foam chemical defoaming fermentation on core material foam plastic board. The heat insulation of urea-formaldehyde foam is very good Good, and it has the advantages of flame retardant, low price and wide sources; but because of its brittleness and serious water absorption, it affects its wide application. Most of the core material foam plastics have the advantages of being soft and strong. For open-cell microcellular foam, it has the characteristics of liquid penetration and can be used Used as filter material, water-absorbing material and flower-tree transplanting material, etc.
