As the name implies, low shrinkage agents for molding resins are mainly used for molding resins. Below we will introduce you from its common characteristics.
Characteristic one, the low shrinkage agent for molded resin has the characteristics of high toughness, low shrinkage rate, and effective prevention of micro-cracks of SMC products.
The second feature is that the low shrinkage agent for molded resin has a certain delay effect on the curing of unsaturated polyester resin, and at the same time, it can better reduce the curing shrinkage of unsaturated polyester resin.
Feature three, low shrinkage agent as a thermoplastic material, non-reactive additive to unsaturated polyester resin. It can be dissolved in styrene or resin mixture to form a stable fractional phase, but it is an incompatible phase in the cured and cured resin.
The above three points are common characteristics of such low shrinkage agents. I believe that under such an introduction, everyone will have a deeper understanding of them. If you have any needs in this regard, please contact us in time.
