Regarding foam packaging materials, do we think that the packaging materials are just foam? In fact, this understanding is not completely wrong, but there are many types of foam liquids. Many of Yichang foam packaging materials are also divided into various types. What are they? ? Let's take a closer look with Yichang Guangming Foam Factory!


First of all, let's talk about the function of Yichang foam packaging. Because the foam produced by different resins has different characteristics. Different types of foam have different uses. The thermal conductivity of ordinary plastic products is mostly in the range of 0.15 to 0.22 W / (m, K), while the thermal conductivity of foam plastic is generally in the range of 0.01 to 0.04 W / (m.K), which is lower than that of ordinary plastic products. 15 to 50 times, has very good heat insulation performance.

The resins commonly used as thermal insulation foam products are rigid PU, PF, urea-formaldehyde, and PS. The thermal insulation performance is as follows: rigid PU> PF> PS. Among them, the thermal conductivity of rigid PU is 0.01 \ .0.03W / (m · K), and the thermal conductivity of PF is 0.02 to 0.04W / (m · K), which is second only to rigid PU, and PS is slightly worse. .


The materials used in Yichang foam packaging have largely solved the problems caused by different temperatures. Among them, urea-formaldehyde foam has good thermal insulation properties, and has the advantages of flame retardancy, low price, and wide source. However, it is widely used because of its brittleness and serious water absorption. 可广泛用于建筑隔热! Can now be widely used in building insulation!

Yichang foam packaging is used in practical applications. Specific insulation foam plastic products are: thermal insulation boxes such as refrigerators, seafood boxes, PS beads foam products; fast food lunch boxes, PS low foam products; roof sheds, walls, etc., PS beads Granular foam board, PF foam product, urea-formaldehyde foam plastic; refrigerator backboard insulation layer, pipe insulation cover, rigid, PU foam material.

With the rapid development of science and technology, Yichang foam packaging has also kept up with the innovation of the times and has greatly improved its production technology. Therefore, when selecting products, we must choose the corresponding products according to our own packaging needs. Only to play the superior performance of Yichang foam packaging!
