Metallocenes meet FDA requirements

Six grades of Exxon Chemical Co.'s metallocene-based propylene homo-polymers, trade named Achieve(reg), are now FDA-compliant, without restrictions, for food-contact applications. Two of the new grades, 1605 and EXPP-68, are said to provide higher heat-distortion temperature and flexural modulus and lower extractable content than conventional homopolymer polypropylene. Grades 3825, 3844, 3854, and 3904 are suited for nonwoven and multifilament fine denier fiber and spunbond applications. Exxon Chemical Co: Product Code 4227
