What are compounds and granules of polymer materials?
What is a polymer compound?
It is a mixture consisting of primary polymer, coloring materials and reinforcing agents that increase the desirable properties of the final product. This process involves combining different materials in a mixer and then processing the resulting mixture to produce the final product.
Applications of polymer compounds
These materials are used in a wide range of applications for various industries. Some of its most common uses are:
Car: Polymer compound materials are used to make car parts such as dashboards, bumpers and tires. These materials are chosen for their durability, strength and resistance to heat and chemicals.
Construction: Polymer materials are used in the production of various construction materials, including pipes, roofs and insulation. These materials are widely used due to their flexibility and resistance to weather and chemicals.
Medicine: In this field, polymer compound materials are used to produce medical equipment, including syringes, counters, and implants. These materials are used in medicine because of their biocompatibility and resistance to bacteria and other pathogenic agents.
Packaging: In the production of packaging containers, polymer materials play an important role and are used in various types, including plastic bags and disposable containers, etc. Flexibility, resistance and strength against humidity and other environmental factors are the reasons for choosing them in this industry.
Advantages of polymer compounds
Customization: Polymer compound combinations allow manufacturers to create materials with specific properties and characteristics that meet their needs. Customization can lead to the production of a more durable and quality product.
Cost-effectiveness: Polymer composites can be a cost-effective way to create materials with specific properties. By combining different polymers, additives and fillers, manufacturers can produce materials that meet their needs without investing in expensive raw materials.
Improved properties: Polymer composition can lead to the production of materials with improved properties such as strength, flexibility and resistance to heat and chemicals. These enhanced properties can make materials more suitable for specific applications.
What is a granule?
Granules are not a type of polymer, but a special form of polymeric material that is granulated for ease of use. Polymers produced in petrochemicals are produced in a special form called granular materials for ease of use. Granules can be made from new polymers and used in various plastic industries, including the production of rubber, electric cables, and various packaging materials. used. In addition, the recycling of plastic waste into expandable pellets is expanding, and they are the raw material of many industries, including rubber, asphalt, and the main furnace fuel.
Types of granules
Polyethylene granule: It has a crystalline structure and is produced in a light, linear and even with a high molecular weight. Among its applications, it is possible to use light weight polyethylene in the production of plastic bags and packaging materials, and linear light polyethylene in the production of electric and communication cables. It also used high molecular weight polyethylene to produce industrial machinery parts and bulletproof clothing.
Polypropylene granules:
The special structure of this polymer, which is in the shape of a ball and is the second most used thermoplastic after polyethylene, includes two different types branched in the textile industry, such as pp and chemical pp. It is used to produce products such as toys, bottles of liquids.
Polyurethane granules
A type of transparent polymer material that allows light to pass through and is used in the production of various products such as car lamps and medical equipment.
Polystyrene granules
Synthetic polymers have three common types, durable and elastic, and the most common type is transparent GPPS. The expansion type of these materials is used in the construction of unolith and building thermal insulation, and the resistance type is used to produce the body of the freezer. It is also used in the medical and pharmaceutical industries.
Application of granules:
The main use of granules is to use them as raw materials in the production of plastic products. Granules are usually used in powder and flakes because of their many benefits.
Granules, whether new or recycled, can be used in various fields of the plastic industry. Depending on the sensitivity, the use of recycled granules is prohibited in some industries. But in general, recycled granules are used in most industries due to their high added value.
