The weather in the north is cold. How to improve the cold resistance of PVC when producing it?

First of all, you can choose PVC resin with a slightly higher viscosity number and a larger average molecular weight. Secondly, you can choose plasticizers, such as DOA/DOS/DIDA/DOZ/DOS as representatives of cold-resistant plasticizers. Third, use modifiers. According to articles reported by Dayi Yousu Plastic Network, CPE can improve the low-temperature performance of products, thereby stabilizing the low-temperature impact performance of PVC products.
