Difference between TPU and PES
2022-10-29
Both Tpu Hot Melt Adhesive film and PES hot melt adhesive film are conventional material types of hot melt adhesives in the hot melt adhesive product system. Their functions are to solve the problem of bonding and compounding of materials, and they are basically the same in terms of production molding process and use method. But what are the differences between them? 1.different materials The difference between the two is first in terms of raw materials. The main component of TPU hot melt adhesive film is polyurethane, which is an elastomer material. The color can also be divided into high transparency, transparent and white matte due to different melting points. The main component of PES hot melt adhesive film is copolyester, which is a white translucent material 2.The difference in softness and comfort The difference between the two in terms of softness and comfort is still relatively large. The TPU hot melt adhesive film has very good elasticity and performs well in terms of softness and comfort. The main raw material of PES hot-melt adhesive film is an inelastic polymer material, so its performance in terms of softness and comfort is relatively poor, far less than that of TPU hot-melt adhesive film. Therefore, the scope of application of TPU hot melt adhesive film is also wider than that of PES hot melt adhesive film. 3.The difference between washable and dry cleaning Both TPU hot-melt adhesive film and PES hot-melt adhesive film have good water-washing resistance, and the water-washing resistance of PES hot-melt adhesive film is better than that of TPU hot-melt adhesive film. However, the washing resistance of TPU hot melt adhesive film can meet the requirements of most industries for washing resistance. However, the performance of TPU hot melt adhesive film is relatively poor in terms of dry cleaning resistance, and the dry cleaning resistance of PES hot melt adhesive film is also good. 4.Differences in temperature resistance The high temperature resistance of TPU hot melt adhesive film is 110 degrees, and the low temperature resistance is minus 20 degrees; the high temperature resistance of PES hot melt adhesive film is above 120 degrees, and the low temperature resistance is minus 30 degrees 5.Difference in melting point The melting point type of TPU hot melt adhesive film is more than that of PES hot melt adhesive film, and the melting point span is relatively large, basically both high and low temperature. The low melting point can reach 65 degrees, and the high melting point can reach 180 degrees. The melting point of PES hot melt adhesive film is basically about 110 degrees, and the span is relatively small Jiangmen M.F.B.S.
