Description
Technical Field
The invention relates to a plastic film formula, in particular to a PVC formula.
Background
The main component of the PVC film is polyvinyl chloride, and other components are added to improve the heat resistance, toughness and ductility of the PVC film. PVC belongs to a strong polar polymer, the melting processing temperature is in the range of 160-210, and the processing temperature is closer to the decomposition temperature. During molding processing, PVC is thermosensitive and extremely unstable after being heated, so that HCl removal reaction of PVC is easily caused, and the melt has high viscosity and poor flowability. In addition, the film products are subject to aging and have limited life cycles.
Disclosure of Invention
The present invention provides a PVC film formulation that solves one or more of the above-mentioned technical problems.
