Today, polyvinyl chloride (PVC) is known as one of the most widely used polymers in the world, which is the third most widely used polymer in the world. Because PVC is one of the most widely used and valuable petrochemical products, it is widely used in various industries. This valuable polymer is present in many products that we consume. PVC is a very resistant and durable material that can be used in various applications with a wide range of colors. Among the industries that use PVC the most, we can mention the construction industry, the production of PVC door and window profiles, the manufacture of medical equipment and wires and cables. In this article, we are trying to discuss the application of PVC granules in industry or the application of PVC compounds in industry.
What is PVC granule and what are its physical characteristics?
PVC granules are a type of plastic material that is produced from polyvinyl chloride (PVC) raw materials. Polyvinyl chloride is a thermoplastic material that is composed of PVC resin with different ratios of fillers, lubricants, stabilizers, pigments, softeners and processing aids. PVC granules are mainly white or light yellow in color and are almost light in weight. And they look like small and round pieces. This material is one of the most important types of polymers, which consists of PVC resin, plasticizers and required additives, which are combined and produced by special machines. PVC granule is used as a popular material in various industries due to its properties such as resistance, flexibility and high durability. For PVC granule applications in industry, different combinations of these materials are used to obtain specific groups of properties for different applications, which are usually the major part of any PVC resin composition.
The reason for the application of PVC compound in the industry is its wide range of properties. This material is supplied in the form of soft (P-PVC) and hard (U-PVC) granules.
Hard PVC granule is used in the production of pipes, window profiles and wall coverings due to its properties such as high strength, durability, hardness and self-flammability. But soft or flexible PVC granules are mostly used in cable industry, shoes and slippers, flooring, toys, gloves and masks.
Among the properties of PVC granules, the following can be mentioned:
- Impact resistant
- Durability and longevity
- flexibility
- Fireproofing
- UV resistant
- recyclable
- to be economical
- Chemical stability
- Mechanical stability
- Low melting temperature
- Ability to process and mold
Examination of hard and soft pvc granules
As you know, PVC granules are one of the most widely used plastic materials in the world and are used in more than 2000 different applications. PVC granules are divided into two categories: soft granules (P-PVC) and hard granules (U-PVC), each of which has its own properties and applications.
Soft PVC: which is also known as flexible PVC and is used in many industries due to its properties such as durability, comfort, and flexibility. Such as the production of cables, medical products, toys, etc., most plastic products are obtained from the combination of soft PVC.
Rigid PVC: u-PVC stands for “unplasticized” and because it does not contain plasticizers and phthalates, it is called a rigid plastic that is easy to maintain.
For durability and resistance to external factors, hard PVC that needs more durability is used, such as Pipes and fittings, window profiles, etc. Hard PVC is more resistant to gas and air pressure than soft PVC. Due to the stronger thermal, mechanical and chemical resistance that hard PVC has, it is used more in various industries. Therefore, the application of PVC granules in industry is very wide.

Examination application of PVC granules in industry
As we have already mentioned the use of PVC granules in the industry due to its properties, now we want to fully examine the use of this valuable material, both soft and hard.
One of the most widely used plastics in the world is PVC, which is widely used in various industries. Among the industries that use PVC granules in the manufacture of their products:
- Construction industry: One of the most common uses of PVC granules is in the construction industry. Due to its properties such as high resistance, light weight and durability, it is mostly used in the production of pipes, fittings, construction floors, doors and windows.
- Automotive Industry: Due to its high resistance to wear and impact, ultraviolet rays and chemicals, PVC granules are used in the production of various internal and external parts of the car, such as internal wires, seat covers, dashboards and steering wheels.
- Packaging industry: Today, the packaging industry is one of the big and vital industries that plays a significant role in maintaining the quality and safety of manufactured products. Due to its transparency and resistance to wear, impact, heat and light, it is used in the production of packaging such as electronic products, packaging of food products, films, foams, containers.
- Production of flooring: PVC compounds are used to make sports flooring, construction flooring and industrial flooring. PVC flooring has properties such as impact resistance, anti-slip, comfortable, waterproof, safe and also cheap.
- Medical industry: PVC granules are used in the manufacture of medical equipment such as blood bags, surgical gloves, masks, etc. due to its properties such as non-toxicity, flexibility and transparency.
- Electrical industry: Due to the electrical insulating properties of PVC granules, they are highly regarded in the electrical industry. PVC granules are used in the production of electrical components, wire and cable covering, insulating tapes. Cables made of PVC granules can easily prevent contact with various materials and electrical disturbances.
- Entertainment and toys: in products made for children, PVC granules are used in products such as balls, dolls, play mats, etc. due to its non-toxic properties, light weight and flexibility.
Other uses of PVC in the industry include the following:
- Agriculture industry
- Household appliance industry
- Stationery
- Sports equipment
- Types of hoses
- Sealant
- False Ceiling

Purchase and price of PVC in different
Due to the applications of PVC granules in the industry and its properties, it is still one of the most affordable polymers in the world, and for this reason, it is used in various industries. One of the factors affecting the price of PVC granules is the quality of the basic polymer that makes it up. The price and cost of PVC products vary according to the raw materials used, type and color. As a result, the price depends on the type of product you choose.
Karachemicals is one of the manufacturers of PVC granules and compounds, which has gained a special place among its customers with its high quality and variety of designs and colors. Karachemicals, which has been successful in the field of PVC so far and is one of the largest manufacturers of PVC granules and PVC compound, publishes the Riyal and Dollar prices of its products weekly on its website.

Granule PVC is a multi-purpose plastic material that has many uses in the industry due to its properties such as resistance to wear, impact, and corrosion, and it is produced in two types, soft and hard, each of which has its own properties. Among the applications of PVC granules in the industry, we can mention the manufacture of all kinds of plastic devices and tools, such as water and sewage pipes, medical equipment, wire and cable, car parts, etc.
The price of PVC granules is different depending on the chosen type and according to its application, it can have a different price. karachemicals company offers its products to its domestic and foreign customers with respect to being competitive with quality and reasonable price.
Hard PVC is more recyclable than soft PVC because it does not contain excess plasticizer concentrations. Soft PVC is difficult to recycle from a hygienic point of view because it contains a higher concentration of plasticizers.
The difference between soft and hard PVC is in their ingredients, even though both use the main raw materials of PVC. In the production of soft PVC, in order to have good flexibility and bend easily, plasticizers are used, so it is easy to shape, but due to the excessive use of plasticizers, they cannot be maintained for a long time.
In the production of hard PVC, no softener is added, that’s why it has stronger thermal, mechanical and chemical resistance, and they are more durable.
