The present invention relates to a foam reduction agent comprising low vapor pressure dibasic esters and a method of using a liquid to contact with polystyrene foam wherein the higher boiling temperature of the low vapor pressure dibasic esters and contact with the liquid provides a volume reduction process and less evaporation loss as well as safer transportation of the chemicals and the polystyrene in its reduced state. The resulting reduced sludge is also recyclable to superior quality raw polystyrene foam beads and the reduction agents are recoverable for future use. The resulting sludge also has unexpected beneficial uses heretofore unknown as a waterproofing agent, a paint stripper, as a graffiti remover, as an extender of the life of concrete, as an adhesive remover, as a stain remover, as a scuff mark remover, and as a general degreaser.

Reduction in polystyrene foams with low vapor pressure dibasic esters

The present invention is directed to novel polystyrene foam reduction recycling compositions and methods that solve the volume problem of recycling polystyrene foam materials while simultaneously allowing the easy and inexpensive shipment of the foamed materials after reduction in volume by use of one or more dibasic ester compositions in combination with one or more low heat based mechanical extruders. The methods of the present invention are applicable to all types of expanded or foamed polystyrene materials known to those of skill in the art.

Methods of reducing polystyrene foams using dibasic esters with extruders

A foam reduction agent consisting of dibasic esters is shown and a process using a liquid contact with polystyrene foam wherein the higher boiling temperature of the dibasic esters and contact with the liquid provides a volume reduction process and less evaporation loss as well as safer transportation of the chemicals and the polystyrene in its reduced state. The resulting reduced sludge is also recyclable to superior quality raw polystyrene foam beads and the reduction agents are recoverable for future use. The resulting sludge also has unexpected beneficial uses hereto for unknown as a waterproofing agent.

Reduction in polystyrene foams with dibasic esters

This invention is a method to speed up and prevent inconsistent rates of reaction in the reduction of volume of polystyrene foam products by the application of a liquid and vapors of a terpine or isoprenoid compound where a heat activation within 90 days of the use provides maximum reactivity. In one embodiment the process is localized by the addition of heaters in the processing vessels or tanks to insure active agent form of d-limonene reduction agent.
