PLASTICIZER ADDS
When you add a plasticizer to your PVC, why not get one that also improves thermal stability? For example, in non-fogging application, you get low volatility and you clamp down on migration problems when you use esters derived from DuPont's pyromellitic acid(PMA). Volatility is below that of dioctyl phthalate.
Good electrical properties are characteristic of PMA esters. In electrical grade PVC compositions, tetra-2-ethylhexyl pyromellitate gives improved volume
RESISTANCE TO VINYLS
resistivity, brittle point and thermal aging. Absence of color and easy processing are additional reasons why you will want to investigate such plasticizers. Try test samples of several esters in your vinyl formulation. For details, please write DuPont, Explosives Department, 2446 Nemours Building, Wilmington 98, Delaware.
