Dioctyl Terephthalate Non Phthalate Plasticizer
Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate or Di(2-ethylhexyl) terephthalate), commonly abbreviated DOTP or DEHT, is an organic compound with the formula C6H4(CO2C8H17)2. It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid used for softening PVC plastics is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications.
Dioctyl Terephthalate non phthalate plasticizer is also used in high-quality lubricants or lubricating additives for furniture and interior decoration paints, coatings and precision instruments, nitro varnish additives, paper softeners, polyester amide biaxially stretched films, film plastic crafts, plasma storage bags, etc. It is a versatile plasticizer.
Dioctyl Terephthalate non phthalate plasticizer is a general purpose plasticizer that is considered safer than ortho-phthalate plasticizers due to its excellent toxicological profile. The terephthalates exhibit none of the peroxisome proliferation of liver enzymes that some ortho-phthalates have shown in several studies. It has uses in applications like extrusion, calendering, injection molding, rotational molding, dip molding, slush molding and coating.
