What is the molding shrinkage of TPEE material after shrinkage?
2024-05-28 15:13
We have been trading and producing TPEE for many years, and almost every year we encounter the problem of shrinkage and shrinkage after forming,
the brands used are disorderly, dupont, Holland, Cologne, SK-made hechuang, Sinopec Yizheng, as well as some home-made modification, filling and regeneration, to this end, we summarized the world's current production of all brands of TPEE polymer raw materials, after the formation of shrinkage ratio, for your reference mold use
After 25 days, the molding shrinkage was 9-10% 0.9%
After 30 days, the molding shrinkage was 9-10% -1.0%
After 35 days, the molding shrinkage was 12-13% 1.2%
After 40 days of molding shrinkage, 13 percent 1.3
After 45 days the molding shrinks by 14 percent to 1.4 percent
After 55 days the molding shrinks, 15-16 percent to 1.5 percent
After 63 days the molding shrinks by 16 percent to 1.6 percent
After 72 days the molding shrinks by 17 percent to 1.7 percent
After 82 days the molding shrinks by 20 percent to 2.0 percent
The above shrinkage is compared with almost all polymer raw material production brands, with a difference of 0.1 percent for the sub-brand regenerated modified filling, except,
