Terephthalates are esters of tere-phthalic acid such as the 1,4 benzenedicarboxilic acid ester known as DEHTP or DOTP which offers low temperature performance, better resistance to soapy water extraction and low volatility. In plastisols, these plasticisers (US: plasticizers) provide lower initial viscosity and better stability but requires higher fusion and processing temperature. Terephthalates exhibit lower levels of compatibility with PVC than ortho-phthalates limiting their use for the production of durable goods.
