Dioctyl Phthalate (DOP), also known as DEHP, is the most widely used general-purpose plasticizer for PVC worldwide. It offers an optimum balance of cost, performance, and processability, delivering excellent flexibility, durability, and electrical properties at a competitive price. DOP remains the industry benchmark against which all other PVC plasticizers are compared.

Frequently Asked Questions (FAQs)

Is DOP the same as DEHP?
Yes. DOP and DEHP refer to the same chemical substance: Bis(2-ethylhexyl) phthalate, CAS 117-81-7.

Can DOP still be legally used in 2025?
Yes, DOP remains fully legal and widely used in industrial and adult applications (cables, flooring, roofing, automotive) outside of restricted categories such as toys, food contact, and medical devices.

Is DOP compatible with other plasticizers?
Yes. Commonly blended with secondary plasticizers (e.g., chlorinated paraffin, TXIB) or high-performance types (TOTM, DINCH) to improve specific properties.

Does DOP have good light and heat stability?
Moderate. Requires adequate heat and UV stabilizers (e.g., epoxidized soybean oil + Ba/Zn or Ca/Zn stabilizers) for long-term outdoor exposure.
