FAIRFIELD, MAINE - Custom Plastic Molding Inc. is licensing its patented process for adding skid resistance to thermoformed plastic products. The process increases the coefficient of friction on plastics by as much as four times that of smooth or embossed grain surfaces, and two times that of coextruded olefins, the Fairfield firm said in a news release.
Custom Plastics currently is developing skid-resistant applications for playground equipment, pallets and other materials-handling products, said spokesman Mitchell Aiello.
Thermoformer Durakon Industries Inc. of Lapeer, Mich., holds an exclusive long-term license for using the process on truck bedliners, according to Aiello.
In the process, the plastic's surface is oxidized, either with flame or an electronic discharge, to create bonding sites on the extruded sheet or thermoformed part; then a two-component thermoset is sprayed on.
``Within one second, 85 percent of the product is cured,'' he said.
The technology requires no adjustments to tooling or product, and is less expensive than coextrusion, he said.
The research firm's main licensees for the process are thermoformers with proprietary product lines, he said. One of its newer offerings, for large-part fiberglass processing, cuts cycle times and reduces styrene emissions, Aiello said.
