UHMW-PE films boost rubber properties.
DeWal Industries in Montreal, which extrudes UHMW-PE films and tapes, says the latest versions of the films are giving a new lease on life to thermoset rubber hose, conveyor belts, and weatherseals. The company uses UHMW-PE films to add abrasion and chemical resistance to rubber products and to reduce their coefficient of friction. Warren DiClemente, DeWal's films business manager, says UHMW-PE films adhere strongly to rubber during vulcanization without tie layers or pretreatment. One application is automotive weatherseals, where 2-mil film is put in high-wear areas (e.g., window channels) of rubber weather-strips. This is said to be a more cost-effective and environmentally friendly alternative to fiber flocking. Films can also be wrapped around hydraulic hose and adhered to conveyor belts used for moving chemicals or foods. Tel: (800) 366-8356, www.dewal.com
