June 1998

electrical wiring into moulded components or products such as automobiles and domestic electrical appliances, it is claimed by the Japanese firm Sinto Kogyo. Moreover, the technology could use standard injection moulding equipment. Based on research by workers at Tokyo University, the project has been assigned by the Science and Technology Promotion Foundation to Sinto Kogyo for further development. It will last two years, with an estimated cost of WOOmillion ($3.27 m) Contact: Sinto Kogyo, 4-7-23 Meieki, Nakamura-ku, Nagoya 450, Japan; tel: +8I-52 582 9211; fax: +8I-52 586 2279

Toyo claims new process for FR polyurethane foam A process for production of flame-retardant rigid polyurethane (PU) foam, using carbon dioxide as the blowing agent, in place of the hydrochlorofluorocarbons (HCFCs) or hydrofluorocarbons (HFCs), is claimed by Toyo Tire and Rubber Co. The foam has a thermal insulation equivalent to that of conventional foams and good heat resistance, claims the company. It has passed the fire resistance test at Class 2 of the construction material standard JIS A- 132 1. The conventional technique for manufacturing rigid PU foam is with HCFC 141b as blowing agent, adding a flame retardant such as alurninium hydroxide, because foam of this type is easily broken down at elevated temperatures. The development is in line with Toyo Tire’s programme to cease using HCFCs entirely by the year 2001. The company plans to start commercial production later in the current year, initially manufacturing about 200 tonnes a month at a price similar to conventional foam. In due course, Toyo may apply the process to its whole range of foams. Toyo Tire and Rubber Co Ltd, I-I 7-8 Edobori, Nishi-ku, Osaka 550, Japan; tel:+8I-6 4418801; jzx +8I-6 445 2225

Urethane cord reinforces power belting Urethane cord is being used as a reinforcement for stretch belting for power transmission and conveying, following development of a proprietary welding process, by DuraBelt Inc, Hilliard, Ohio, USA. The company fabricates the belts from extruded urethane elastomer cord, cut to length and welded into an O-ring. This is then twisted, leaving a small loop at each end. The loops are joined together with a connector, creating an O-ring of the twisted cord. The stretch belts permit very fast changeover compared with traditional endless Orings, and are oRen used as replacements when conveyor belt drives or other power transmission belts break. It is essential to minimize downtime and these belts provide quick fixes to keep the production line up and running. They are also used in full-time application.
