PVC Processing Aid is an additive used to improve the processing performance of polyvinyl chloride (PVC). Its main function is to promote PVC melting, increase melt strength, improve surface quality, and reduce processing defects. Due to poor thermal stability and high melt viscosity, PVC is prone to problems such as melt fracture and surface roughness during processing. The addition of processing aids can significantly optimize its processing performance.
PVC processing aid can promote melting, increase friction between PVC particles, accelerate melting speed, and make plasticization more uniform; Improve melt strength, prevent melt fracture, reduce extrusion swelling, and enhance processing stability; Improve surface smoothness, reduce surface defects such as flow marks and shark skin, and enhance the appearance quality of products; Enhance thermal stability, some processing aids can assist with thermal stabilizers to reduce PVC degradation; Optimize the processing window to maintain good processability of PVC over a wider temperature range.
PVC processing aid is mainly divided into acrylic processing aid and San processing aid. Acrylic processing aid, such as polymethyl methacrylate (PMMA) based processing aids, have high melt strength, good surface finish, and are suitable for both hard and soft PVC. Mainly used in profiles, pipes, sheets, and transparent products. SAN processing aid, with lower cost but slightly inferior performance to ACR, is mainly suitable for general PVC products such as cables and films.

The product is mainly used in industries such as PVC pipes, PVC profiles (doors and windows), PVC films, PVC transparent sheets, wires and cables.
PVC processing aids are crucial in PVC processing, especially for hard PVC products such as pipes and profiles. ACR processing aid has become the mainstream choice due to its excellent melt strength and surface finish, while SAN processing aid is suitable for cost sensitive applications. In the future, with the advancement of PVC processing technology, high performance, environmentally friendly, and multifunctional processing aids will become a development trend.

Properties : Foam regulator is a key functional additive in the production of PVC foam products (such as foam boards, foam profiles, decorative boards, etc.), mostly high molecular weight acrylic ester (ACR) modified products. Its core function is to enhance the strength and viscosity of PVC melt, stabilize the cell structure during foaming, avoid bubble rupture, merging, collapse or perforation, and thus form a fine and uniform closed cell structure in the product. The use of appropriate foaming modifiers can significantly improve the surface smoothness of PVC foam products, reduce product density, and reduce weight, while enhancing dimensional stability and mechanical properties. It effectively solves common production problems such as surface roughness, collapse, uneven density, and coarse foam pores, and is one of the core additives to ensure the quality and production yield of PVC foam products.
