Identification method of plastic particles such as PP|PC|ABS|PA|POM|PC/ABS (1/2)

In the development process of plastic industrialization, the molecular structure and composition of plastic particles are extremely complex, and there are many types, including PP, PC, ASB, PA, POM and PC/ABS. The colors of single materials are transparent, translucent, slightly yellow, etc. Color, it is difficult for ordinary people to identify its actual name and style. As a manufacturer that mainly produces resin granular plastic raw materials, Forever Co., Ltd. needs to briefly explain to its customers how to identify such complicated plastic raw materials. , there are only three main methods: appearance identification, density and quality identification and combustion characteristics for exclusion identification.

1: Use the method of hand feeling and visual appearance identification

PP, PE, and PA have different bending properties, feel smooth, and have a soft keratin-like sound when struck. However, plastic materials such as PS, ABS, PC, and PMMA have no ductility and have a rigid and fuzzy feel. , the sound is crisper when struck. Of course, it is impossible to distinguish them at all. For example, the characteristics of PE and PP are very similar, and the single hardness is lower than that of PP, so you should be more careful when identifying them.

The difference between PS and modified PS and ABS is that the former is brittle, while PS and ABS have better toughness. PS bends easily and breaks, while PS and ABS do not.

Color distinction:

PP plastic particles are milky white, translucent, and waxy.

ABS plastic pellets are ivory color.

PC plastic particles are yellowish and transparent.

PA plastic particles are light yellow and translucent.

The appearance of PC/ABS plastic is opaque and ivory-colored pellets
