NEW YORK - Monsanto Plastics introduced a clear ABS resin for medical applications that the firm said provides good chemical resistance and processability at a lower cost than polycarbonates. The Lustran ABS 266 Mediclear resin is designed to meet the growing demand for clear plastics in the medical field. Citing figures from Business Communications Co. Inc. of Norwalk, Conn., Monsanto said U.S. consumption of clear plastics will top 2 billion pounds in 1999, a 5.4 percent annual growth rate compared with the 1.5 billion pounds consumed in 1994.
The new resin is a ``drop-in'' for medical device makers already processing ABS, said Victoria M. Holt, commercial manager for Monsanto's Medical and Personal Products Team.
``Those people who are molding ABS now do not have to change their tools to mold this new ABS,'' she said.
The resin was introduced at the Medical Design & Manufacturing Show.
Lustran ABS 266 Mediclear contains methyl methacrylate to boost impact strength and toughness. Monsanto Plastics also said gamma sterilization testing of ABS resin showed ``negligible discoloration.''
The firm, a unit of St. Louis-based Monsanto Co., offers the new resin at $1.90 per pound.
