PVC Resin

- Jan 23, 2018 -

PVC resin is a polar amorphous polymer, there is a strong force between the molecules, is a hard and brittle material, low impact strength. After adding the impact modifier, the elastomer particles of the impact modifier can reduce the total ripple initiation stress, and use the particle's own deformation and shear band to prevent the expansion and growth of the silver grain, absorb the impact energy of the incoming material, and achieve the aim of resisting the shock. The particle of modifier is very small, in order to increase the quantity of modifier in unit weight or unit volume, increase the number of effective volume, and thus enhance the ability of dispersing stress. At present, it is widely used as organic impact modifier.
