What is the PVC processing aid ACR?

ACR is the abbreviation of acrylate, and it is also the general name of acrylate series modifiers. It is a polymer of acrylate, white powder, easy to flow, non-toxic, non-corrosive, fine in particle size, and its true density is 1.05- 1.20 g/cm. The main purpose of ACR is because ACR has obvious advantages as a processing aid, which can obviously shorten the plasticizing time, accelerate the melting speed, promote plasticization, improve the balance torque under the condition of frequent extrusion and make plasticization uniform. For some calendered products, adding an appropriate amount of ACR can overcome surface wrinkles, which is beneficial to material wrapping and reduce bubbles. For vacuum-formed products, adding ACR can improve melt ductility, overcome melt fracture, facilitate deep drawing and make the thickness of products uniform. From the appearance of the product, ACR can obviously improve the surface gloss of the product and make the product look smooth and delicate.
