What is the shrinkage rate of TPE?

Generally, the shrinkage rate of TPE is about 15-30 per thousand, because TPE is a new material polymerized from many materials, depending on what kind of TPE material is selected. For example, the TPE shrinkage of transparent PP package is between 15-22, and the transparent ABS is between 20-30, so it is said to shrink.

TPE injection molding process can reduce the shrinkage of TPE materials, so when designing the mold, we should consider the influence of TPE shrinkage on the appearance of products as much as possible, especially thick-walled products.
