Use of UV absorbers in the production of transparent polyamide molded parts
 
Buhler and Meyer Zu Westram of EMS, Switzerland, used an UV absorber in the transparent polyamide products or polyamide molded parts. This UV absorber must have a substituted benzoyl group.  The result is that such polyamide melts molding compounds leave no visible blooming on surfaces during processing of polyamide products.  UV absorbers in the form of a dibenzoylmethane compound and/or an aminohydroxybenzoyl benzoic acid ester are preferred.  (RDC 5/16/2012)
