[0015] definition

[0016] Unless otherwise indicated, all numbers expressing amounts of ingredients, properties (such as molecular weights), reaction conditions, etc. used in the specification and claims are to be understood as being modified in all instances by the term "about". Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired characteristics sought to be obtained by the present invention. At the very least, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Additionally, the ranges stated in the disclosure and claims are intended to specifically include the entire range and not just the endpoints. For example, a range declared as 0 to 10 is intended to disclose: all integers between 0 and 10, such as 1, 2, 3, 4, etc.; all decimals...

Abstract

The present application discloses a novel plasticizer formulation comprising bis(2-(2-butoxyethoxy)ethyl) terephthalate, bis(2-ethylhexyl) terephthalate, and optionally tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate. The plasticizer formulation is suitable medium to high temperature applications such as wire and cable insulation and jacketing.

Description

Background technique [0001] Currently used plasticizers suitable for medium to high temperature applications such as wire and cable insulation and jacketing applications are trimellitates (e.g. TOTM, TINTM) and high molecular weight phthalates (e.g. phthalates diisodecyl formate (DIDP), diundecyl phthalate (DUP)). These plasticizers show good compatibility and persistence in PVC systems. However, trimellitate-type plasticizers are difficult to process due to lack of efficiency, and high molecular weight phthalates have health concerns (eg, DIDP is listed on California Proposition 65). The present application discloses novel non-phthalate plasticizer compositions that are cost effective and provide good performance and better regulatory compliance. Contents of the invention [0002] The application discloses a plasticizer composition, which plasticizer composition comprises: [0003] (1) 50wt%-70wt% terephthalate bis (2-(2-butoxyethoxy) ethyl) ester I; [0004] (II) 30wt%...
