What are the functions of PVC processing aids?

1. PVC processing aids PA-20 and PA-40, as imported ACR products, are widely used in PVC transparent films, PVC sheets, PVC particles, PVC hoses and other products to effectively improve the dispersion and thermal processing performance of PVC mixtures, surface brightness, effectively reduce waste generation, and solve the problems of flow marks and crystal points that are prone to occur in production.
Due to its ultra-high molecular weight, PA-40 is widely used as a foaming regulator in PVC foam boards, PVC foam pipes, and other products, resulting in uniform foaming and high product quality.
2. Impact modifier MBS Impact resistant MBS resin is mainly used in the PVC processing and forming process to improve its impact strength without damaging the inherent characteristics of PVC. Due to its similar solubility parameters to PVC, the two have good thermodynamic compatibility, characterized by high impact strength, temperature resistance, and coloring properties of PVC at room or low temperatures. Transparent modifier MBS Transparent MBS resin is mainly used in the processing and forming of transparent PVC products, improving their impact strength without damaging the inherent characteristics of transparent PVC products. Its refractive index is similar to PVC, and using MBS as a PVC impact modifier will not affect the transparency of PVC. It is the best material for improving PVC impact resistance and manufacturing transparent products. Compared with other companies, our MBS has higher impact resistance, better compatibility, and wear resistance MBS enhancer BLD-81 (impact modifier, focusing on PVC pipes and fittings) is used to enhance the strength and weather resistance of PVC profile products.
