Introduction Of PVC Plastics And Common Lubricant Applications

Shandong Polymer Additives Co.,Ltd | Updated: Nov 23, 2018

The lubricant used in plastic processing is a compounding agent added to improve the fluidity and mold release property of plastics, particularly thermoplastics, during processing.

 

Lubricants are used in a wide range of applications. Hard PVC, polyolefins, polystyrene, ABS, phenolic resins, chitosan acetate, unsaturated polyesters, and rubbers use some lubricants when processing. But the main use of lubricants is still in the rigid PVC, so the rigid PVC is the center. The amount of the lubricant varies depending on the type of the resin, but generally 1 to 2 parts of the lubricant is obtained in 100 parts of the resin to obtain a good lubricating effect.


PVC profile is one of the main varieties of PVC hard products in China, accounting for 22.9% of the total consumption of PVC resin, and growing at an average rate of more than 7% per year. China's production capacity is more than 2,800 Kt. The setting of PVC formula system and the selection of various plastic lubricants are important factors to ensure the quality of PVC profiles. In addition to the stabilizing system and modified system, the processing properties of the lubricating system on the profiles and the appearance and physical properties of the products. The indicators have a big impact. Due to the small amount of use, its important role is often overlooked. Many defects in the processing of PVC profiles and finished products are closely related to the selection and proportioning of lubricants. Therefore, lubricants are formulated in PVC profiles. Has a very important role.
