Several points to be noticed in the application of PVC processing aids

There are many kinds of PVC processing aids. When processing resin products, PVC processing aids are selected according to demand. What should be paid attention to in the application of PVC processing aids?

1. Impact modifier: When processing plastics, if the impact modifier is not added, the finished plastic products will become very brittle and hard. A slight impact will cause cracks, which can not guarantee the quality and service life. The function of the impact modifier is to make the plastic products more resistant to the force of the external environment.

2. Heat stabilizer: plastic processing and molding will be heated. During the heating process, plastic will inevitably have unstable performance. The purpose of adding heat stabilizer is to stabilize the performance of PVC materials during heating.

3. Improved processing aids: The so-called improved processing aids, as the name implies, are to improve some properties of PVC processing, including improving the poor fluidity of PVC, which is easy to stick to the equipment for coking. Therefore, a certain amount of processing aids need to be added in the production of plastic profiles to overcome the defects of plastic profiles themselves.

4. Filler: Filler is a solid additive different from plastic in composition and structure, also known as filler. It has obvious effect and economic value on improving some physical and mechanical properties of plastics and reducing the cost of plastics. Adding fillers into the production formula of plastic profiles can reduce the size change rate of plastic profiles after heating, improve impact strength, increase rigidity, and reduce production costs.

5. Light stabilizer: light stabilizer can inhibit the photooxidative degradation reaction of polymers by shielding and absorbing ultraviolet rays, quenching and exciting energy to capture free radicals, etc., so as to give products good light stabilization effect and extend their service life.

6. Lubricant: The main function of lubricant is to reduce the friction between polymer and processing equipment and between molecules inside polymer, prevent resin degradation caused by excessive friction heat, and improve the efficiency of heat stabilizer.
