Recycled GRS refers to the recycled raw materials, which are superior to new materials in some properties, some properties are the same as new materials, and some are still inferior to new materials.

How to identify the GRS of recycled materials? Let's take a brief look at it.

1. Look at the brightness of the surface.

2. Look at the whiteness, not only the surface, but also the whiteness of the cut surface.

3. Look at the hardness. Take a bite with your teeth and you will know that the good material is hard. Too soft means impure.

4. To see whether it sinks, it depends on the amount of stone powder. Generally, there will be more or less stone powder in the recycled materials, because the incoming raw materials are not very pure. If no stone powder is added, it will not sink.

What is the use of recycled GRS? Let's take a brief look at it. Recycled material GRS is usually produced by the recovery of chemical products, through some processing means, to produce a variety of corresponding products. Different product requirements, the nature of recycled materials are also different, so the use of recycled materials can produce different products because of the problem of world resources. More and more users use recycled materials, and manufacturers of plastic products are increasingly interested in the use of recycled materials.

  Recycled material GRSWhat are the classifications? Let's all have a brief understanding. According to the different materials, recycled materials GRS has many kinds of classification, the general plastic recycling material is more, recycled plastic particles according to the different raw materials used and the characteristics of the recycled plastic particles after processing. It is generally divided into primary recycled plastic particles, secondary recycled plastic particles and tertiary recycled plastic particles.

Recycled material GRS: Grade I means that the raw materials used are leftover materials that have not yet fallen to the ground, also called leftover materials, and some of them are nozzle materials, rubber head materials, etc. They are all good quality, unused, small leftover materials in the processing of new materials, or recycled plastic particles of poor quality. The recycled plastic particles processed from these woolen materials have good transparency and are comparable in quality to new materials, so they are called primary recycled plastic particles or super recycled plastic particles.

Level 2 refers to the raw materials that have been used once. Except for high-pressure recycled plastic particles, most of them are imported large ones. If the imported large piece is industrial film, without the wind and sun, then the quality is also very good, and the transparency of the processed recycled plastic particles is good. At this time, it should also be judged according to the brightness and roughness of the recycled plastic particles.

Recycled material GRS: Grade III refers to recycled plastic particles processed from raw materials that have been used twice or more. Its elasticity and toughness are not very good, so it can only be used for injection molding, while 1. Grade II recycled plastic particles can be used for film blowing, wire drawing and other purposes. Grade II recycled plastic particles: close to raw materials, 80-90% of raw material price; Grade I recycled plastic particles: 70-80% of raw material price; secondary recycled plastic particles: 50-70% of the price of raw materials; tertiary recycled plastic particles: 30-50% of the price of raw materials. From the quality points: drawing, blowing film, spinning, primary, secondary, injection filling, etc.
