How to distinguish waste plastics from ABS/GPPS/HIPS

How to distinguish waste plastics from ABS/GPPS/HIPS：

There are many ways to identify ABS hooks. As far as ABS is concerned, the surface brightness is good, and the toughness is better than that of PS. After burning, there will be dense holes on the surface, and the taste is slightly sweet; PS is divided into three types: GPPS, HIPS, and EPS. , There are more brittle and transparent products. The brightness of HIPS is average, and the toughness is inferior to ABS. After burning, the surface is bright and has the taste of styrene. The truncated surface of HIPS is whitish, but GPPS is not, EPS is mainly used for foam.

        For supermarket display hooks, there are ABS and HIPS, which are generally distinguished according to surface characteristics and physical characteristics. The best surface brightness is generally ABS. When broken with pliers, ABS is better than HIPS. Its hardness is higher and requires strength. Larger, and then differentiated by flame and flavor.
