Detailed identification method of ABS hook and PS hook

Detailed identification method of ABS hook and PS hook:

1. Common methods

As far as ABS hook (styrene, butadiene, acrylonitrile copolymer) is concerned, the surface is bright, hard (relative to HIPS material), high strength, folded into a white shape, and its toughness is better than PS, and the flame is yellow when burning, and there is no dripping of molten liquid. , After the fire, there will be dense small holes on the surface and a special smell.

(Polystyrene) is divided into three types: GPPS (general-purpose polystyrene), HIPS (impact-resistant polystyrene), and EPS (expandable polystyrene board). There are many brittle and transparent products. HIPS The brightness is average, the toughness is inferior to ABS, it is flammable, it is orange-yellow and flashes when burning, the thick black smoke leaves the flame and continues to burn, softens, foams, smells aromatic, and the surface is bright after burning.

The truncated surface of HIPS is whitish, but GPPS is not, EPS is mainly used for foam.

Our common TV casing materials are divided into ABS and HIPS, which are generally distinguished according to surface characteristics and physical characteristics. The best surface brightness is generally ABS, which is better than HIPS when broken with pliers. A little stronger and then differentiated according to the flame and flavor.

2. Pure ABS and HIPS are better to distinguish, with ethyl acetate sassafras, HIPS will be silky and ABS will not be silky.
