The properties of trimellitates allow high-performance vinyls to be formulated at favorable cost/performance ratios.

Trimellitate plasticizers offer many of the performance advantages of both polyester and phthalate plasticizers. Trimellitates have high-temperature permanence that equals or exceeds polyester plasticizers. Unlike polymeric plasticizers, trimellitates also provide flexibility at low temperatures.

ANDERSON DEVELOPMENT CO.

Offers its TGD plasticizer, which appears to be stable in polyether and polyester urethane elastomers at levels up to 20%. It is useful to lower the hardness of polyurethanes and in low levels for reducing the viscosity of prepolymers.

Properties of Viplex 895, the most widely used of the Viplex series, include high solvency and excellent gel. Viscosity of a plastisol using Viplex 895 is said to be higher than is possible with DOP alone, and much higher than one with dodecylbenzene. Replacement levels for phthalate plasticizer are 70% or more.

For epoxies, Viplex 885 is a low-viscosity plasticizer/extender than can be added at levels around 20% to either resin or catalyst prior to combining and is said to improve sprayability.

For urethanes, Viplex 525 is a low-viscosity flexibilizer/extender that can be added to the resin or polyol before combining to affect viscosity reductions, good wetting of pigment, fillers and glass, less pinholing, reduced exotherm, and improved moisture resistance.

For polyesters, Viplex 885 is said to improve tensile strength and impact resistance. It reduces mold shrinkage and markedly reduces water absorption.
