黑色PP回料 PP再生料 高韧性 聚丙烯颗粒 手电筒外壳用塑料 (CAS No.None)

Product Name:Recycled Polypropylene (PP) Granules

English Name:Recycled Polypropylene (PP) Granules

CAS No.:9003-07-0

Aliases:Black PP recycled material, PP regrind, High-toughness polypropylene granules, Plastic for flashlight housings

Molecular Formula:(C3H6)n

Physical Properties:This product is in the form of black granules, odorless, tasteless, and non-toxic. Density 0.89~0.91 g/cm³, tensile strength 21~39 MPa, flexural strength 42~56 MPa, compressive strength 39~56 MPa, elongation at break 200%~400%, notched impact strength 2.2~5 kJ/m², low-temperature notched impact strength 1~2 kJ/m², Rockwell hardness R95~105. It has good heat resistance with a continuous service temperature of 110~120℃; good chemical stability, resisting most chemicals except strong oxidants; excellent water resistance and good electrical insulation. However, its weathering resistance is poor, requiring antioxidants or UV absorbers.

Uses:Mainly used for injection-molded products such as flashlight housings, offering high toughness and good rigidity. It is also widely used in automotive parts, medical devices, conveying pipes, chemical containers, and other production fields. Note: recycled products must not be used for food packaging.
