The material formula for plastic pipe extrusion
Oct 20, 2017

Most of the plastic products, such as polyethylene, polypropylene, polystyrene, EVA, ABS, PET and so on, are directly supplied by the resin factory. The pellets have been added directly to the extrusion process. Plastic products factory needs its own formulation and preparation of powder or granular material is polyvinyl chloride, this kind of plastic needs to add appropriate stabilizers, lubricants, plasticizers, coupling agent and antioxidant, colorants, fillers and other additives in the resin, need to use the kneading machine, open mill, internal mixer or extruder machine to complete high-speed mixing, granulation. The formulation is designed to improve the processability, inherent quality, and reduce cost of the resin. The formulation design should be based on the properties, applications, service life, compatibility of additives and resins, interaction and synergistic effects among various auxiliaries and characteristics of processing equipment.
