Charkit Chemical
Covalent Chemical
Diethyl Hexyl Terephthalate
Odor: characteristic
Use: PLASTHALL® DOTP can be classified as a highly permanent monomeric phthalate. This type of plasticizer finds utility where particular permanence requirements must be met, for example, in distilled water and humid environments. Due to the higher molecular weight of PLASTHALL DOTP, efficiency and low-temperature properties are compromised.

Dioctyl Terephthalate (DOTP)
Odor: characteristic
Use: DOTP is a general purpose plasticizer that is considered safer than ortho-phthalate plasticizers due to its excellent toxicological profile. It has uses in applications like extrusion, calendaring, injection molding, rotational molding, dip molding, slush molding and coating.
