Learn more about PVC Plasticizers - DOP and DOTP
Normally, DOP tends to be the cheapest PVC plasticizer, mainly due to the economies of scale achieved by this material, which means that its offer is greater than DOTP. In Plastisol, DOP is preferred because it does not generate so many “pin holes” defects because it doesn’t affect viscosity, allowing volatile substances to leave the paste.

Advances in PVC plasticiser technology
Plasticizers are almost 30% of weight of product, and are added to PVC to make it flexible and durable. Phthalates are the mainstay plasticizers. Unfortunately, they migrate to the surface of the plastic over time and escape into the environment, making PVC less flexible and durable.
- What plasticizers are used in PVC?
- About 80% of all plasticizers are used in PVC. Typically phthalic esters such as dioctyl phthalate (DOP), also known as di-2-ethylhexyladipate (DEHA) are used as plasticizers. These are needed to protect the product from deterioration by sunlight or even supermarket lighting.
