A new line of high-specifi c-gravity compounds from GE Plastics/LNP Specialty Compounds, Exton, Pa., are intended for lead replacement in radiation shielding. Thermocomp HSG compounds of nylon 6 highly fi lled with tungsten metal are said to deliver x-ray and other radiation shielding equal to lead. The compounds range in specifi c gravity from 2 to 11. Due to increasing regulation of lead for its environmental toxicity, manufacturers are said to be seeking replacements. For example, the European Union's Restriction of Hazardous Substances (RoHS) directive calls for near-elimination of lead in most electrical and electronic equipment. Injection molded parts offer several advantages over machined and stamped lead, including tighter tolerances and greater part consistency, plus fewer secondary operations. GE Healthcare uses the new compound in an x-ray machine collimator. Tel: (610) 363-4500 . www.geplastics.com
