WHARTON, N.J.—Toll compounder Dynepco Corp. is expanding its materials range to include thermoplastic elastomers and polyolefins.
The Wharton-based firm will start operating a 140-millimeter Buss kneader in July and will add another, a 70mm model, by year's end, said Valerie Telford, sales and marketing manager. She did not disclose cost of the equipment.
Dynepco mainly compounds engineering resins, including glass-and mineral-filled polymers, on eight single-screw extruders. Its two twin-screw extruders can handle conductive compounds that contain carbon fiber, iron powder and copper and aluminum flake. Each twin-screw is housed in a separate, explosion-resistant enclosure. The twin screws recently began commercial production of conductive materials after Dynepco spent about $2.7 million on the machinery and development work during the past few years. It moved to its current 100,000-square-foot facility in 1993.
Telford said the kneaders will allow her firm to compound carbon powders and work with ethylene vinyl acetate, wire and cable polyolefins, elastomers, biodegradable polymers and blowing agents.
Dynepco, a subsidiary of Daicel Chemical Industries Ltd. of Tokyo, has annual capacity of about 20 million pounds, said Dynepco President Thomas Cunningham. Daicel's sales are about $2 billion a year.
