Support pad for air conditioning condenser unit or the like

DETAILED DESCRIPTION OF THE INVENTION As indicated above, there have been many efforts in the past to provide a support pad for supporting an air conditioning compressor unit or the like.
The present invention solves the problems of the past by providing a strong, light-weight support pad for such purpose wherein a molded body is formed of a mixture comprising recycled crumb rubber and sufficient recycled polyethylene to bond the crumb rubber together into a resilient solidified pad, with the amount of the crumb rubber preferably being about 25 percent, but may be in the range of about 20 to about 40 percent by weight of the total mixture.
The "crumb rubber" as used herein refers to rubber of small particle size in the range of 10-200 mesh, and preferably 30-40 mesh which has been ground or buffed from a scrap rubber tire, in which virtually all metal and non-rubber fibers are removed.
The rubber may be either natural or synthetic rubber found in automobile and/or truck tires.
The polyethylene used in the composition of this invention is preferably recycled polyethylene, and it may be an expanded polyethylene resin such as disclosed in U.

3,790,115, or a solid polyethylene, so long as the polyethylene is capable of being heated and softened for mixing with the crumb rubber to bond the crumb rubber together.
Although it is preferred to have the crumb rubber and the polyethylene as essentially the only components in the pad, impurities or other materials may be present so long as they do not interfere with bonding of the polyethylene and the crumb rubber into the pad.
Example: By way of example, the product of this invention is molded from: about 50% by weight of high density polyethylene (HDPE) about 20--about 40% by weight of crumb rubber having the particle size in the range of 10-200 mesh about 5% by weight of low density polyethylene (LDPE) about 5% by weight of polypropylene film scrap about 5% by weight of nylon scrap about 9% by weight of CaCO.
