    Abstract: A castliner in the form of a three-dimensionally knitted sleeve comprises a microdenier yarn, and/or a spandex yarn, in particular, a spandex yarn having a flatter stress-strain curve than traditional spandex yarns. The use of the microdenier yarn contributes to the superior cushioning effect. The stretch and recovery properties of the particular spandex yarn contribute to superior fit and reduction of pressure points on the limb or body part to which the castliner is applied. Furthermore, the castliner is rendered water resistant and has significantly improved antimicrobial properties, both of which reduce incidents of skin irritation and unpleasant smell. As a result, the patient wearing the castliner of the invention is able to bathe and get wet without otherwise replacing the hard casting and castliner after such events.

    Abstract: This invention relates to toluate ester compositions and their use as solvent, plasticizers, extender and/or diluents in binder formulations, a method of producing such ester compositions, as well as polymer compositions containing such liquid ester compositions. The method of making toluate based esters by reacting methyl-p-toluate with ethylene glycol, diethylene or triethylene glycol, butanediol, etc. More particularly, this invention relates to the mono-­or di-ester of methyl toluic acid with a diol containing 2 to 6 carbon atoms that are low viscosity liquids at 25° C. The most common polymer that employs plasticizer is polyvinyl chloride (PVC). Typical amounts of plasticizer in PVC are from about 3 wt. % to about 50 wt. %. Phenolic resins generally require solvents, diluents and/or extenders that reduce the volatility and viscosity of the resin, especially when it is used in building and automotive products. Typical amounts of solvent are from about 5 wt. % to about 65 wt. %.
