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...

Types and Specifications of Plastic Extruders
Jan 19 , 2016
Plastic extruders are used to create a wide range of items, including plastic tubing, trims, seals, plastic sheets and rods. Extruder is the machine for producing more or less continuous lengths of plastic sections out of a selected type of plastic resin. The essential elements for a thermoplastic extruder are a tubular barrel, usually electrically heated; a revolving screw, ram or plunger within ...
