Scope: This document specifies the classification and naming, requirements, test methods, inspection rules, signs, packaging, transportation and storage of recycled polypropylene plastics. This document is applicable to polypropylene recycled plastic granules made from waste polypropylene plastics through screening, sorting, cleaning, melt extrusion granulation and other processes (including granulation processes such as stranding, hot cutting and/or water cutting) , the matrix of the polypropylene recycled plastic is all propylene homopolymers specified in GB/T2546.1 and propylene copolymers with a mass fraction of other 1-olefin monomers less than 50% and blends of the above-mentioned polymers with a mass fraction of not less than 50%. thing. This document does not apply to polypropylene recycled plastics from medical waste, hazardous waste such as pesticide packaging, and radioactive waste. This document does not apply to polyethylene and polypropylene mixed recycled plastics.
