PVC is the abbreviation for Polyvinyl Chloride. This is a thermoplastic made from the polymerization of Vinyl chloride. PVC Granules is the earliest plastic material created in the plastic industry. According to our research, PVC plastic has been known since 1835. However, it was not until 1937 that this plastic material was put into large-scale production. Up to now, PVC is used to replace some other materials to increase efficiency. As well as reducing the cost of purchasing products.
PVC resin has no odor, usually produced in solid form. With the characteristic white color, there are also some other colors such as: Amber or colorless. As a result, PVC has now become an indispensable material in the production of electrical pipes, wires and cables. Basically, this plastic material is not toxic, it is only toxic when combined with some additives in the production process.
Features of PVC you should know:
As mentioned above, PVC is the earliest specialized plastic resin in the history of the plastic industry. Therefore, it also possesses many outstanding features not all plastic materials have. To help you better understand PVC material, let’s take a look at some of their outstanding advantages.
- PVC has very good chemical resistance.
- Resistant to hydrolysis (hot water and steam).
- Besides, PVC can also resist ultraviolet rays.
- In addition, this specialized plastic bead can also self-fire and prevent electromagnetic contamination.
- Even virgin PVC is used in the production of food grade materials.
- Good price.
- Easy to blend fiberglass to increase hardness, impact resistance. Metallic additive for use in machinery and resistant to high temperatures up to 150 degrees Celsius.
Although possessing a lot of advantages, but like other plastic beads. PVC also has certain limitations. Typically as:
- Low durability in low temperature environments.
- Along with that is poor wear resistance.
- When encountering an environment with a high temperature above 120 degrees Celsius, it will easily catch fire, causing an unpleasant odor.
What are the physical properties of PVC?
Usually PVC granules have a white or yellow powder. They are not toxic, only toxic when additives are added. And usually exists in two forms:
Highlights of PVC granules:
- PVC.S: This is a suspension of PVC resin with a relatively large particle size. Ranges between 20 and 150 microns.
- PVC.E: High fineness emulsion PVC resin.
This plastic material has poor bearing capacity, so to increase impact, people often add MBS or ABS in the production process. Besides, PVC has good electrical insulation, so it has become the main material in the production of electrical insulation.
- PVC has a molecular formula of (C2H3Cl)n.
- This plastic material is quite chemically inert.
- The typical reaction is the dehydrochlorination reaction.
With the above sharing, do you know what PVC beads are? Along with that are the outstanding advantages and basic properties of PVC. Thanks to the above outstanding features, up to now, PVC plastic has been applied in many different areas of life. From producing plastic sheets to making vinyl floors, pipes, pipe fittings. Each PVC field plays a different role. Specifically:
PVC in the production of vinyl flooring:
Perhaps you are no stranger to imitation wood flooring, one of the products widely used in construction today. Products with high aesthetics, high durability are made of PVC material. Thanks to the composition of PVC, the plastic floor has high durability. Moreover, it is not affected by weather conditions, outstanding moisture resistance, waterproofing and anti-slip properties. Therefore, it becomes a modern flooring material, suitable for the climate of our country.
PVC in the production of plastic pipes:
Currently, PVC is also the main raw material in the production of plastic pipes. One of the products used to conduct water or other liquids in households, factories, and industrial zones. This product line is designed with many different sizes. Depending on the needs of use and properties of plastic can be divided into two types as follows:
The role of PVC in the production of electric wires and cables:
Thanks to its good electrical insulation, PVC is also a raw material for the production of electric wires and cables. Depending on the classification, characteristics and properties of the cable, the manufacturer will add the necessary additives. Although PVC itself is fire resistant. But to increase safety when manufacturing cables, people will add flame retardant additives in the production process.
Production of PVC film:
Besides the above applications, today PVC is also used in packaging, raincoats. In this field, PVC is divided into the following types of films:
To get the product with the right hardness. In the production process, people often add content of additives to create plasticity for the product.
Why is PVC plastic granules commonly used in packaging production?
At this point, you probably know what PVC beads are? And also know that PVC has many advantages. In particular, PVC is non-toxic, highly resistant to gas and water vapor. Along with that is the mechanical strength, good heat resistance. Therefore, PVC is applied in many fields in modern life. And food packaging is one of the outstanding applications of this specialized plastic.
