Plastic Glides: A Second Look

 

Mr. Edmund Fisher’s Technical Briefarticle, “Comparing Four Plastics as Scenery Glides” inspired the technical staff at Wilkes College to try plastic glides. At our local plastics distributor’s suggestion, we used ultra-high-molecular-weight polyethylene (UHMWPE) in place of Mr. Fisher’s “clear winner,” Delrin®. The UHMWPE glides worked so well for us that they warranted further scrutiny. This article reports the results of our investigations.

Mr. Fisher’s test sought to compare the coefficients of static friction of four plastics on three fairly standard deck materials. We wanted to test the coefficients of kinetic friction of plastics we are likely to use. While the coefficient ...
