ACR is the abbreviation of acrylic esters (Acrylics), and is also the general name of acrylic ester series modifiers, acrylic polymer copolymers, fluid white powder, non-toxic, non-corrosive, non-dangerous goods , the particle size is finer, and the true density is 1.05-1.20g/cm. The main purpose of ACR is to be used as a processing aid, because ACR has obvious advantages as a processing aid, which can significantly shorten the plasticization time, speed up plasticization, and promote plasticization. , and the frequency of extrusion can improve the balance torque and plasticize evenly. For calendered products, adding an appropriate amount of ACR can overcome surface wrinkles, which is conducive to material wrapping and reducing air bubbles; for vacuum-formed products, adding ACR can improve the melting point. Body extensibility, overcome the phenomenon of melt fracture, easy to deep-draw forming, and make the thickness of the product uniform. From the appearance of the product, ACR can significantly improve the surface gloss of the product, making the product look smooth and delicate.
