Dioctyl Terephthalate (DOTP)
ATICPLAS200®
-
DOTP is the ester of terephthalic acid and 2-ethylhexanol. It is a clear, colorless liquid, which is insoluble in water. Dioctyl terephthalate is a very important phthalate-free plasticizer for PVC, preferred over low-chain and ortho-phthalate plasticizers as it is considered a safer alternative due to its lower toxicity.
-
DOTP is used mainly to plasticize vinyl resin where good processing characteristics are needed, and the finished product requires low temperature flexibility and low volatility.
