Impact modifier: When processing plastics, if no impact modifier is added, the finished plastic will become very brittle and hard. If it is slightly hit, there will be cracks and quality and service life cannot be guaranteed. The role of impact modifiers is to make plastic products more resistant to the external environment.
Thermal stabilizer: The plastic processing and molding will be heated. During the heating process, the plastic will inevitably exhibit a function of unstable function. Participation in thermal stabilizers is to stabilize the function of PVC materials in the heating process.
Improved processing aids: The so-called improved type, as its name suggests, is to improve some of the functions of PVC processing, including improved PVC's poor fluidity and simple coking on the equipment, so it is required to participate in a certain amount of processing in the production of plastic profiles. Additives to overcome the shortcomings of the plastic profiles themselves.
Filler: A filler is a solid additive, also called a filler, that is different in composition and construction from plastic. It has obvious effects and economic value for improving certain physical and mechanical functions of plastics and reducing the cost of plastics. Participating in the filler in the plastic profile production formula can reduce the dimensional change rate of the plastic profile after heating, the impact strength is improved, the rigidity is added, and the production cost is also reduced.
Light stabilizer: Light stabilizer can shield the photo-oxidative degradation of the polymer by masking and absorbing ultraviolet rays, annihilating energy scavenging free radicals, etc., thereby giving the finished product excellent light stability and extending their service life.
Lubricant: The main function of the lubricant is to reduce the friction between the polymer and the processing equipment and between the molecules inside the polymer, to avoid degradation of the resin due to excessive frictional heat, and to increase the power of the thermal stabilizer.
