PP placemat factory teaches you how to identify PP plastic material

       PP placemats are one of the many products on our market, especially for some customers in the south who have a special preference for PP placemat materials. Below, our PP placemat factory will teach you how to identify PP plastic materials

       We need to learn to distinguish products from several aspects such as color, luster, hardness, etc. Firstly, let's take a look at the brightness of the product. Generally, products with good whiteness have higher quality. We can also use teeth to test the hardness of the product. Products with high hardness have good quality, but some soft particles cannot be ordered. Furthermore, we can also distinguish product quality by observing the floating behavior of particles. We can put plastic particles into water, and those that are submerged in water have quality problems, while those that float on the water surface are of good quality plastic particles. These are some good methods for identifying the quality of PP plastic particles. At the same time, these methods are relatively simple to use and do not require too much time, making them quite feasible.
