Toray launched polyolefin foams with 60 times foaming rate

Toray Japan has developed polyolefin foams that can be used as water stop materials in the fields of automobiles, household appliances, residential equipment and facilities. The new product can replace the ordinary water stop material - ethylene propylene diene monomer (EPDM) and polyurethane foam. It is estimated that the sales volume will reach 500million yen in 2012 and 1billion yen in 2015

the maximum foaming ratio of traditional polyolefin foams is about 40 times that of downstream PCB enterprises, with low bargaining power, while the foaming ratio of new materials has increased to 60 times. Dongli said, "in terms of the foaming ratio of polyolefin foams, this is probably the highest level in the world". Due to the increased foaming ratio, compared with ordinary polyolefin foams, the new product improves the softness when compressed, and can be used as water stop material. Polyolefin foams with a foaming ratio of about 40 times have strong resilience when compressed, so they cannot be used as water stop materials after being compressed on the original thickness

the key to improving the foaming ratio is the "ultra-high foaming technology", which is foaming after increasing the temperature of the resin sheet and reducing the viscosity of the resin, which can increase the proportion of gas in the foaming structure, and in almost all downstream industries, it can also maintain excellent softness after compression, so as to realize the characteristics of deformation along a variety of shapes, so I will pay a high salary to hire; No equipment
