ACR (Acrylic Processing Aid) is a commonly used plasticizing processing aid in PVC product processing. It can effectively control the phenomenon of melt fracture, promote the gel plasticization of PVC, and improve the plasticizing quality. During PVC processing, ACR can reasonably increase the melting torque and balance torque of materials, shorten the gel plasticizing time of materials, and reduce the processing temperature.

ACR belongs to the acrylic copolymer class and usually has a "core-shell" structure. This high molecular weight additive can significantly improve the processing performance of PVC. Although its dosage in the formula is relatively small, it has a significant impact on the processing performance of PVC.

ACR is particularly widely used in the field of rigid PVC injection molding. It can not only promote the melting of PVC resin, but also improve the rheological and lubricating properties of the melt, thereby reducing molding defects, improving product yield and quality. Specifically, ACR can prevent molten PVC from adhering to equipment, improve metal delamination, and does not affect the transparency of PVC, nor does it have post-processing migration. 

In addition, ACR can also be used in combination with other additives such as stabilizers, lubricants, etc. for better synergistic effects and no adverse reactions.

ACR processing aid as an efficient PVC processing aid, plays an important role in improving processing performance, enhancing production efficiency, and improving product quality. When selecting and applying ACR, it is necessary to determine the most suitable type and dosage based on specific product requirements and processing technology to achieve the best processing effect.
