Granule – classification of granule types

The name granule may have been heard by most of those who work in the plastic and polymer industry. The story started from a place where, with the advancement of technology, various methods and devices were created to produce plastic products, and the question was raised as to what the primary material used in these devices should be.

Among the forms of powder, granule, and flakes, granule has won this competition because of its many advantages. In most production methods, the granule is used as a raw material to produce the final product. But what is granule and what are its advantages? What types are there? How is it produced? If you have questions like this in your mind, stay with us in this article to get the answers to your questions.

What is a granule?

The wrong image of granules in the minds of some who have little knowledge of polymer and plastic is that this product is a type of polymer material. As the first and most important point, you should know that granule is not the name of a specific polymer and it is a form of polymer that has changed from a powder state to a granular form (like the image below) and is used in various applications and uses.

The reason for using granules is the ease of use in production; The powders are dispersed in the air, and in addition to the pollution of the workshop environment and the breathing problems they cause, a large amount of material is also wasted, but the granule does not have these problems.

In addition, the system of plastic forming machines is designed in such a way that its raw materials are better in the form of granules. Therefore, manufacturers prefer to use its granular form instead of powder form. To produce polymer products from granules, they must first be melted and then shaped.
