The Cold-Resistant Performance of Soft PVC Film

---

PVC plastic material is one of the five general-purpose synthetic plastics, Due to the poor cold resistance and low temperature impact resistance of PVC, the application of PVC plastic materials is limited in some field.

The brittle temperature is an index for the cold resistance of soft PVC film.Use an impact shape to impact a PVC plastic sample of a specification and size at a low temperature state at a certain speed, the temperature at which 50% of the PVC plastic sample breaks is the embrittlement temperature. The embrittlement point of soft PVC film will be reduced with the adjustment of the amount of plasticizer and the addition of impact modifier.

DOA, DIDA, DOZ, DOS, which are cold-resistant plasticizers with excellent low temperature performance.

The impact modifier and PVC resin are with similar solubility parameters and certain mutual solubility, and form a blend with a bright structure, thereby improving the low temperature impact strength of the soft PVC vinyl film.

POLYSAN is professional plastic film factory in producing cold resistant and anti-UV soft PVC film, and keeps good physical and mechanical properties at Max minus 30°C. Low temperature soft PVC film sheet can be used in the production of construction, packaging materials, electronic materials, daily consumption, etc. It is widely used in industry, agriculture, construction , transportation, power communication and packaging and other fields.
