The use of lead has always been considered a necessary issue in any X-ray device used in medical and industrial equipment. Intrinsic physical properties, such as malleability and density, allow this metal to fit perfectly into a wealth of X-ray shielding applications as covers, support and lining of housings and enclosures.
Current reliable solutions consider an overwhelming usage of metallic lead sheets and its oxides eg litargirium. Sheets are modeled and shaped by the means of human labor as well as thermoset resins filled with lead composites used to mould semi finished parts – all these parts often have to be reprocessed and finished creating lead exposure hazard.
Difficulties related to handling production and disposal of lead and derivates can generate extra costs and represent a severe issue becoming more and more dramatic as health and environment care laws and norms narrow applicatoon possibilities.
Restrictions are already applied in many industrial fields and may soon be extended to untouched sectors. Trying to always be a step ahead in the search of lead free and non toxic solutions, LATI has created LATIGRAY a full range of radiopaque thermoplastic compounds dedicated to lead and heavy metal substitution in X ray shielding application.
Injection moldable LATIGRAY compounds are obtained by filling radiopaque additives with a thermoplastic matrix chosen on the basis of a project’s requirements. It is possible to fine tune shielding efficiency and contrast by modifying filler type and amount from just opaque to completel shielding.
LATIGRAY can deal with lead frames showing the same shielding power at very similar thickness. Those compounds are produced on PP, PA, PPS, PBT etc with ceramics and/or metal powders to achieve the best shielding performance.
