Detailed knowledge of PVC processing modifiers

Traditionally, process modifiers almost exclusively refer to modification aids used in the processing of rigid PVC to improve the plasticizing properties, improve the viscoelasticity of the resin melt and promote the melt flow of the resin, and such aids are mainly acrylate copolymers (ACR), which have a prominent role in the processing of rigid PVC products. The modern sense of the concept of processing modifiers has been extended to polyolefins (such as linear low-density polyethylene LLDPE), engineering thermoplastic resins and other fields, it is expected that in the next few years the metallocene resin into use will also appear newer and wider varieties of processing modifiers.
