China Plastics Network teaches you how to judge the quality of recycled plastics

First, we can look at its color first:

The lighter the color (even colorless and transparent), the wider the range of use and the higher the level. Such as white, it can be adjusted into a variety of other colors, but also can be used as a white product, the same price is also high.

Second, look at the CaC03 (stone powder) content:

The more CaC03 content, the lower the grade, the lower the price. From the naked eye, the product is not bright, dull (except matt), the CaC03 content will be more, and it will feel heavy from the hand. If it is burned with fire, the burnt part will turn red and become gray. In addition, we must pay attention to the enhancement (referring to glass fiber) products. The enhanced products that can be used are only PA, PBT, PP, etc., and the price is not high. There are also several kinds of alloy materials. At present, there are only one kind of ABS+PC in China, and the others will not work. According to the specific gravity (density) of the raw materials, it can be judged whether the mixed materials can be reused. At present, the most problem is the mutual mixing of ABS and PS, the mutual mixing of PC and PMMA, the PVC flakes (bottle) and PEl, and the flakes. Mixed, PE and PP are mixed with each other. After mixing these materials, the density is similar and it is difficult to use.

Then, you can see that the recycled plastic material is pure and impure:

The purer the material, the higher the grade; the material is impure and the grade is low.

The above three points can identify the quality of recycled plastics. I hope the above data will help you.
