Descripción del producto

PVC processing aid is widely used in the processing of PVC products, such as extrusion, injection molding, blow molding,blistering and calendering .It adheres to the PVC resin particles through a long molecular chain, transmits the external heat and shear force to the resin, promotes its melting and plasticization, reduces the temperature of the processing process, improves the melt strength, improves the appearance quality of the products, and doesnt reduce the rigidity of rigid PVC.


According to different molecular weight,acrylic processing aid is divided into low molecular weight processing aid,medial molecular weight processing aid and high molecular weight processing aid.They used in different application,the low molecular one used in transparent film or sheet,the medial one used in general pvc products like pipe,fitting,profile.The high molecular processing aid used foam products like pvc foam boad,sheet,WPC.
