Diisodecyl Phthalate (DIDP)

Description

What is Diisodecyl Phthalate (DIDP)?

Diisodecyl Phthalate (DIDP) is a high molecular weight phthalate plasticizer widely used in the plastics and polymer industry. With excellent resistance to heat, UV rays, and volatility, DIDP provides long-lasting flexibility, durability, and performance to various PVC-based products. Compared to other phthalates, DIDP is especially valued for applications requiring high temperature resistance, low migration, and extended product life.
