As an important formula component of PVC flexible products, plasticizer has a great influence on the performance of PVC flexible products. If PVC soft products (PVC cold storage door curtains) are required to be used at low temperatures, plasticizers with good temperature resistance must be selected

DOP and DOTP are general-purpose plasticizers used to make PVC softer, more flexible and easier to process. The main difference is their molecular structure: DOP, usually referring to DEHP, is an orthophthalate, while DOTP, also called DEHT, is a terephthalate and is commonly selected as a non-orthophthalate alternative.
