Today, many industries use PVC compounds depending on the desired applications in the production of their products. Therefore, these days, the demand for this valuable material has expanded a lot. Therefore, in order to produce a PVC product, it is necessary to first know the types of PVC compound and its use in order to produce a high quality product that meets the needs of our customers. PVC compound is a combination of PVC resin and various additives, which is used in a wide range of applications in various industries due to its high resistance, durability and versatility. PVC is normally white in color and has extreme fragility and vulnerability to environmental damage, which allows compounders to improve the properties of polymer materials by adding some additives, for example, it increases the durability of PVC compounds or it can be changed its properties, for certain applications. PVC compounds are usually produced in two types, hard and soft, and have different applications. In this article, we are trying to discuss the types of PVC compound in different industries and examine its role in the industry. Follow us for more information in this field.
Physical characteristics of PVC granules
PVC granules are granular in white color. These granules are almost odorless and can be produced in different colors depending on its type and application. The diameter of PVC granules is usually between 2 and 4 mm and has a specific weight of about 1.4 grams per cubic centimeter. The hardness range of hard PVC granules is 40 to 90 and has a density of 1.3-1.45 g/cm and for soft PVC the hardness range is 40 to 100 with a density of 1.1-1.35 g/cm. Their melting point is between 170-210 degrees Celsius, which is difficult to melt hard PVC compared to soft type.The tensile strength of PVC granules is high and it is used in many industries due to its high flexibility. Among its other physical properties, we can mention impact resistance. All types of PVC compounds have a high resistance against impact, wear and corrosion, and also have a good thermal expansion coefficient, for this reason, they are very durable and are a suitable option in many applications. In addition, they have a very good resistance to chemicals such as dilute acid, alkalis, oils and greases, aliphatic hydrocarbons and halogenated hydrocarbons.
What types of PVC compounds are used in different industries?
As we mentioned earlier, PVC has different types, each of which is suitable for a specific application and has the potential to be customized for a wide range of products.The types of PVC compound consist of things like polymer, stabilizers, lubricants, softeners, fillers, pigments, polymer processing aids, impact modifiers. PVC is produced in two different types, soft and hard. Although their main raw material is PVC, there are differences in their ingredients.Soft PVC, also known as P-PVC, is created by adding some additives such as PVC-compatible plasticizers that lower the crystallinity and make the final product have good flexibility and shape.This type of PVC is used in products where durability and good elasticity are important.The most industries that use soft PVC in the production of their products include the following:
- Footwear and clothing industries: (shoe soles, soles, slippers, sports clothes, boots and artificial leather)
- Sports equipment manufacturing industries (safety helmets, boxing gloves, tatami mats, sports flooring)
- Automotive industry (seat covers, panels, steering wheel and interior decorations)
- Electrical industry (insulated wire and cable)
- Toy industry (playroom mats, puzzles, dolls, etc)
- Hose industry (types of hoses for domestic or industrial and agricultural use)
Another type of PVC compound, hard PVC or UPVC, is mostly used to produce products that require high strength and stiffness.As a result, no softener is added to hard PVC. Among the most common industries that use hard PVC are the following:
- Pipe and fittings industry: (water and sewage pipes, fittings)
- Wood industry (production of PVC cover and furniture)
- Electrical industry (production of wall mounts, junction boxes, outlet covers)
- Door and window profiles industry (in the production of door and window profiles, window frames and edge strips)
Price and purchase of all types of PVC compounds
Today, according to market fluctuations, the price of PVC is calculated on a daily basis. The prices of PVC compounds and PVC granules are different depending on their type and application.Many manufacturers are active in this field, therefore, to buy PVC compounds, you should pay attention to many things, including its quality and price.Karachemicals is one of the top manufacturers of PVC compounds and granules, which has always provided the possibility of purchasing for the number, and you can get all kinds of soft and hard PVC compounds from this collection.
Conclusion
Today, PVC is one of the most widely used polymers in the world. With the increasing use of PVC compounds in various industries due to its many properties, the demand for this valuable material is expanding and many industries are using it in their product production. The application of PVC granules is different according to the type and properties they have, and they can be customized depending on the type of use. Therefore, it can be ordered in different colors and with special features and applications. For more information about the price of various PVC compounds, you can refer to the websites of PVC manufacturers and suppliers, the specialized website of Karachemicals search engines.
