Plastic net teaches you how to identify ABS and PS

Regarding ABS and PS, it is sometimes difficult to distinguish between them. The following is a small series of Jiuzhi Plastics Network to tell you how to identify ABS and PS:

1. The new method: rubbing with ethyl acetate, ABS can not afford silk, HIPS will take off, but only refers to pure.
2. Common methods: There are many ways to identify ABS and PS. As far as ABS is concerned, the surface brightness is good, the toughness is better than PS, the surface will have dense pores after burning, and the taste is light and sweet; PS is divided into GPPS. , HIPS, EPS three, more brittle, transparent products, HIPS brightness is generally, toughness is less than ABS, the surface is bright after burning, styrene taste. The section of HIPS is whitish, but GPPS does not. EPS is mainly used for foam.
For TV casing materials, there are ABS, HIPS points, which are generally distinguished according to surface characteristics and physical characteristics. The surface brightness is generally ABS. When using pliers, ABS is better than HIPS, and its hardness is high. Be more powerful and then distinguish them based on their flame and taste.
