Application of PVC blowing agent

1. Used as filler filler filler is one of the main participation forms of PVC except foaming agent. It is a solid additive that is different from plastics in composition and structure. It has obvious effect and economic value on improving some physical and mechanical functions of plastics and reducing the cost of plastics. Adding fillers in the production formula of plastic profiles can reduce the change rate of the size of the plastic profiles after heating, improve the impact strength, add rigidity, and reduce the production cost together.

2. As a thermal stabilizer in the foaming of some plastic products, it is inevitable that the plastic will have unstable functions during the heating process. At this time, properly filled with PVC blowing agent can be used as thermal stabilizer to stabilize the function of PVC material during heating.

3. It is used as an improved processing aid to improve some functions of PVC processing, including poor fluidity of improved PVC, which is simply stuck on the equipment for coking. A certain amount of processing aids can also be added to the production of plastic profiles to overcome the shortcomings of plastic profiles.
