PVC impact modifier is limited in many fields because of its poor impact resistance, especially low temperature impact resistance and poor weather resistance. Therefore, it is necessary to add impact modifier to improve its toughness and weatherability.
Usage: added in the production process of PVC to increase the hardness and impact resistance of PVC. In industrial and civil applications, PVC has many excellent properties and is widely used. However, PVC resin is a brittle material. The continuous glass phase can't prevent the crack from expanding violently under the stress, and finally it forms a gap and cracks, so its impact resistance is poor, but its impact strength and low-temperature impact strength are not good. Therefore, PVC impact modifier should be added to PVC processing and molding to change this shortcoming. Composition: olefin polymer composed of butadiene (more than 55%) and styrene, the specific content is adjusted according to the requirements of upgrading.
