Leonard Chemical's two new propylene-ethylene copolymer resins are transparent and can be used for blow molding, film and sheet extrusion. Leondale Chemicals' PP 30HF01 and PP 33HF04 were produced by adding Milliken Chemical's Millad 3988 clear agent, which is said to provide faster cycling, good dimensional stability and toughness for the two new copolymers. And meet FDA requirements for food contact. Leondale Chemicals also currently supplies PP 33HR01 and PP 43QW02, which are manufactured with Milladyl 988 clear agent, for extrusion molded food storage containers and lids [3].
