Granule is a type of polymer, which is used in the plastic industry. This substance has different types, including transparent and colored granules. In this article, we will try to fully explain the differences between transparent and colored granules. The unique properties of polymers have placed them in the category of the most widely used materials in the world. Their lightness compared to materials such as metals has made it possible to use plastics in different conditions and places. The insulation of plastics against electricity, which has led to the widespread use of this polymer in electrical and electronic industries, such as covering all types of wires, cables, electrical devices and tools, making various types of keys, screws. Due to the transparency of some plastics, they can even replace glass. Colorability, due to which plastics can be used in the production of parts that do not need to be painted. Due to the high resistance of some of these types of polymers, they can be used in different weather conditions and different regions of the country.
What is a transparent granule?
This transparent material is also used in many other industries. Polycarbonate granule can be easily matched with building materials due to its transparency and light transmission and glass-like appearance. Another feature of this material is that it can be changed only with high heat. Another thing that exists, polycarbonate granules can be said to be an amorphous material, which means that it also has the characteristics of crystalline solids. Amorphous solid is a shapeless solid with irregular arrangement of atoms. These materials do not have a specific melting point due to the disorder in the structure of their atoms and they gradually soften with high ambient temperature.
Polycarbonate granule is called resin because of its characteristics. It is used in making ornaments and kitchen appliances. There are many types of polycarbonate that are reinforced with some glass fiber addition with melt flow variance. Among the disadvantages of transparent polycarbonate granules, it should be said that these materials do not catch fire when they are exposed to a lot of heat, such as sunlight in the hot seasons of the year, but they are smoke-producing. Another disadvantage is the high cost that must be paid for its preparation. Granules are produced in two ways, either recycled or new. If we want to produce it in a new form and raw materials from the beginning, it will cost a lot and its production will also take time. One of the most important and extensive parts of the plastic industry is the recycling of plastic waste into reusable granules for other manufacturers, because the raw materials of this industry are used and stored tires in different regions of the country, which are abundant in Iran and annually Several thousand tons are added to their volume.
What is a color granule?
Colored granules are a type of polymers and by combining granule pigments with polymers, colored granules are produced. You can find out the quality of these colored granules from the transparency. This colored granule, if the quality of its raw materials is high, products can be prepared from it, which will attract more attention, higher attractiveness and better quality. Colored granules are also prepared in two ways, new and recycled. Many ways can be used to produce colored granules. Polyethylene, polystyrene, polyamide, polycarbonate, and polypropylene polymers were used to produce colored granules. Next, these materials are poured into the extruder and by using any of the three methods of underwater cutting, ring cutting and dry production, it is possible to go through the production process of this quality transparent colored granule. In the underwater cutting method, molten materials are taken under water and cut at a high speed. In the dry production method, molten material is poured from cold pipes until it dries and is cut after drying. In the ring cutting method, the granules are made into lenses and are cut together with cold water. If high-quality materials are not used during the production of granules, the final product will not be of high quality and will have a dull color.
Application of colored granules
Colored granules, due to their coloring and quality, can be said to have made the products of this material more attractive, and by purchasing colored granules, manufacturers produce products with high attractiveness and excellent quality, and with this They both increase their sales and increase the attractiveness of the products. Colored granules are used in the product packaging industry, carpet and automotive industry, production of all kinds of toys, production of cosmetics and hygiene materials, household appliances and containers, disposable medical equipment containers.
Granule
Since colored and clear granules are very different, the products that are finally produced from there are also different. Colored granules are produced with polymers such as polyethylene, polypropylene, polystyrene and other polymers, and only colored powders are added to them. These products, which are obtained from colored polymers, are usually more attractive. But transparent granules are used in construction purposes such as production of products such as glass. One of the thermoplastics that can be used in the preparation of transparent granules is polycarbonate.
Result
Granule is a material that is combined with polymer and produces a material that is similar to glass in terms of strength and appearance. Among the polymers that are combined with granules are polypropylene, polystyrene, polyamide and polycarbonate. Polycarbonate granules can be used to produce products in the form of glass with high transparency. Polycarbonate starts to soften with high heat, but does not catch fire and in some cases smokes. This transparent granule is also known in the market under the brand name resin. Resin is used in the production of kitchen and decorative products. Granules can generally be prepared in two ways, either by using so-called new raw materials or by recycling, which is through It is more affordable. Transparent granules are used to cover greenhouses, swimming pools, and skylights. Another type of granules is colored granules. This granule is obtained by using pigments that are combined with polymers. Colored granules are usually more attractive when buying, and they are used in the carpet industry and automotive industry. In terms of pricing, granules are usually in such a way that the quality of its raw materials should be examined first and priced accordingly. But in colored granules, in addition to discussing the quality of the raw materials and the transparency of the products, attention should also be paid to the colors used in it. For example, pale blue and deep blue colors are different from each other in terms of pricing.
