Its portfolio includes general-purpose plasticizers, as well as specialty plasticizers such as adipates
, polymerics, or trimellitates.
Non-phthalates include adipates
, terephthalates, benzoates, and bio-based plasticizers.
The following families of plasticizers were studied: phthalates of linear alcohols: DEP, HNP, NUP and DUP; phthalates of branched alcohols: DIBP, DIHP, DOP, and DINP; dialkyl adipates
: DHA and DINA, polymeric adipates
PA3 and PA7; citrates: ATBC and ATHC, pentaerythritol esters H600 and H700, and miscellaneous linear dialkyl esters/EHBDC, ASE and DINCH.
Eastman plasticizers for PVC include phthalates as well as adipates
Classic low-temperature plasticizers, such as adipates
, are limited in their ability to deliver flexible end-product performance," says ISP's Hasan Kaytan.
Found in:Flexible plastics, including shower curtains and vinyl flooring, and nail polish, hair sprays and some perfumes Safer alternative: Adipates
which do not have hormone disrupting properties can sometimes be used
Polyester polyols are usually adipates
of lower molecular weight diols, such as ethylene glycol, propylene glycol, butanediol (BDO) or hexanediol.
In contact with hot and/or fatty foods, PVC can also leach chemicals such as adipates
and phthalates, which have been shown in mice to cause birth defects and damage to the liver, kidneys, lungs and reproductive systems.
According to the speaker, studies compared polyurethanes made with these polyester polyols versus other polyols such as hexane diol adipates
, polycaprolactone, hexane diol carbonate, PTMEG, PPG, and polybutadiene diols.
In contact with foods, especially hot, fatty foods, PVC can also leach chemicals such as adipates
and phthalates, shown in mice to cause birth defects and damage to the liver and kidneys.
Currently, the cost of alternative plasticizers such as adipates
, trimellitates and citrates is 50%, 100%, and 140% higher than that of DEHP, respectively.
have been shown to potentially leach into foods, and their effects are being studied in laboratory animals, but effects on humans--if any--are not known.
