The selection of these materials is to be made bypersonnel with expertise in the plastics field where the environment, inherent properties of thematerials, performance of the part, part design, manu
4、facturing process, and economics are considered.1. Scope*1.1 This specification covers polypropylene materials suit-able for injection molding and extrusion. Polymers consist ofhomopolymer, copolymers, and elastomer compounded with orwithout the addition of impact modifiers (ethylene-propylenerubber
5、, polyisobutylene rubber, and butyl rubber), colorants,stabilizers, lubricants, or reinforcements.1.2 This specification allows for the use of those polypro-pylene materials that can be recycled, reconstituted, andreground, provided that: (1) the requirements as stated in thisspecification are met,
6、and (2) the material has not beenmodified in any way to alter its conformance to food contactregulations or similar requirements. The proportions of re-cycled, reconstituted, and reground material used, as well asthe nature and the amount of any contaminant, cannot bepractically covered in this spec
7、ification. It is the responsibilityof the supplier and the buyer of recycled, reconstituted, andreground materials to ensure compliance. (See Guide D7209.)1.3 The values stated in SI units are to be regarded as thestandard.NOTE 1The properties included in this specification are those re-quired to id
