PVC compound, preparation method and application thereof

The invention relates to a PVC compound, a preparation method and an application thereof. The PVC compound mainly contains the following components in parts by weight: 100 parts of PVC resin and 30-1500 parts of TPU, preferably 40-1200 parts and optimally 50-900 parts. The compound can be used for preparing a sealing strip of a refrigerator. Compared with the traditional PVC sealing strip, the sealing strip prepared from the compound has the advantages of higher mechanical property, rebound resilience, solvent resistance and mobility resistance.
