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...
