Analysis of plasticizing mechanism in each area of twin screw extruder for PVC products
Jan 06 , 2023
According to the plasticizing process of PVC material in the twin screw extruder, the screw is divided into three areas: solid conveying zone, melting zone, and melt conveying (extrusion) zone. 1. Plasticizing mechanism in solid conveying area In the machine barrel, the flow, preheating and compaction area of solid polymer (PVC) and its additives is defined as the solid conveying area. First of al...

Properties of PVC impact modifier and its application
Apr 11 , 2023
PVC resin is a hard and brittle material with poor impact strength, generally only 3-5 kJ/m. The main reason for the need to improve the impact strength of unplasticized PVC is its sensitivity to notching. Besides, it is necessary to improve its low temperature impact resistance. By co-blending impact modifiers in PVC polymers, the toughness of PVC materials can be increased．These impact modifiers...

What is PP PPR PE PVC pipe extruder machine？
May 06 , 2023
PP PPR PE PVC pipe extruder are available as single screw extruders and twin-screw extruders. The appropriate extruder will generally be selected according to the specific material. The material transport of single screw extruders is mainly by friction, which leads to a limited dosing performance, with powders, pastes, glass fibers and inorganic fillers being more difficult to incorporate. Further...
