Pvc Processing Aids Pa-218B

This product has good compatibility and dispersion with PVC, promotes PVC melting and plasticization, effectively reduces PVC melting processing temperature, and improves the weather resistance of the product on the basis of small energy saving.It has excellent metal peeling property, improves the surface finish of products and extends the PVC processing and production cycle.It has excellent flow performance, improves the wrapping with resin, and improves the ring stiffness and longitudinal shrinkage of the product.•It can change the melt rheological behavior of PVC materials, improve the fluidity of PVC materials, thereby making it easier to mold and extrude, ensuring the stability of long-term processing and molding.It can improve the melt strength of PVC materials, avoid melt cracking, solve surface problems such as shark skin, and improve the internal quality and surface gloss of products.It can effectively prevent pressure fluctuations and flow scars caused by extrusion molding during extrusion and injection molding, and effectively avoid surface problems such as ripples and zebra marks.• Due to uniform plasticization, it can also assist in improving the tensile strength, impact strength, elongation at break, and other mechanical properties of the product.
