Application of granules in industries: What is the use of compounds in industries?

Plastics are essential and sustainable materials that are used in our daily life. Many of these plastic products are made of various compounds. Due to the many properties of compounds, many industries use them in the production of consumer products in a wide range.Polymer compounds are one of the most widely used and applied polymer materials in the chemical industry, which are used to increase the strength and stability of plastic materials.In fact, these compounds, which are a combination of polymer and a kind of powder, are used to strengthen polymer structures. By using this method, the application of granules in industries increases and compounds that have less weight, more durability and more efficiency are created, which are used as raw materials for other industries.In this article, we tried to examine the application of compounds in industries. Follow us to understand the use of compounds.

What is a compound?

Compound refers to a type of polymer material that some additives are used in the plastic injection process to increase its physical, chemical and thermal properties, and it can be produced in different grades. The application of compounds in industries is due to properties such as high flexibility and increased strength and resistance for the preparation of polymers and their use. In general, compounds consist of three components, polymer base, compatibilizer and additives, which are responsible for improving the properties of granules. The most effective ones in the compound production process are polymer base and additives. Additives maintain the performance and properties of materials. Some of the most common additives include the following:

•  Fillers: These additives are used to improve durability, strength and dimensional stability. Among these fillers, we can mention calcium carbonate, talc and soil. In addition, adding these materials to the base polymer increases their thermal resistance and process control. Also, due to the cost-effectiveness of these additives, many manufacturers use them in the final products to reduce the production price.
•  Colors: In this particular additive, the selected color can be different according to the polymer used, because these two combined materials must be compatible with each other, and its purpose is to change the color of the final product. To create different colors in the compound, mineral and organic colors, dioxide, black carbon and titanium are used.
• Antioxidants: Antioxidant additives are added to the final product to prevent the deterioration of plastics and increase their durability and lifespan, because plastics degrade when exposed to sunlight, and this degradation leads to color change, brittleness and losing some of its physical properties. Examples of antioxidants include phenols, arylamines and phosphates.
• Flame retardants: This type of additive is used to increase the compound’s resistance to fire and heat. These inhibitors can be combined with base polymers or added to the polymer during the plastic processing stage or added as a surface layer on the final product. The most common use of these materials is in electrical products because it prevents plastics from burning and being used. Phosphorus, nitrogen and halogens are among the most common flame retardants.
• Plasticizers: Polymers without any plasticizer are normally rigid and do not have much flexibility, so they do not have enough properties for plastic processing for some applications. Therefore, they are added to the polymer to improve the production process and increase the ease of working with the compound. These softeners improve the elasticity properties, which are one of the most common polymer additives, which, for example, can be added to the phthalates used in PVC compounds. Cited.
•  Stabilizers: These types of additives are added to the raw material of the polymer to increase the stability and longevity of the compound, and they are one of the most necessary additives because these materials prevent the color of the final product against ultraviolet rays.

Types of compounds

Compounds are composed of different types and are used in different industries depending on their type and application. The most common ones include:

Polyethylene compound

Among the applications of compounds in industries, we can mention polyethylene compound, which is one of the most widely used and important compounds among other compounds and is one of the most used plastics in the world. Polyethylene (PE) is a light and versatile synthetic resin that is formed from the polymerization of ethylene and has properties such as high resistance to direct sunlight and various mechanical impacts, which in addition has ideal quality.

And it has a very reasonable price.There are different types of polyethylene compounds and each one is suitable for a set of applications depending on their properties. For example, high density polyethylene (HDPE) has higher tensile strength than other polyethylenes. It is often used in completely different applications than low-density polyethylene (LDPE), which has low tensile strength but good flexibility.

 Ultra-high molecular weight (UHMW) polyethylene offers high-performance properties in applications such as the construction of heavy-duty pipes in the oil and gas industry, medical devices, waste disposal pipes, and bulletproof vests. Linear light polyethylene (LLDPE) has better mechanical properties and is mostly used in the production of polymer films with higher strength and tensile strength. In terms of polymer structure and density, medium density polyethylene (MDPE) is between heavy polyethylene and light polyethylene, and they are specially used in the production of large tanks for water storage, etc.
