PVC plastic is a widely used thermoplastic in various industries. It boasts numerous advantageous qualities such as durability, chemical resistance, and affordability. Join EuroPlas in exploring all the information about PVC plastic in this article.
1. What is PVC plastic?
What is PVC material? PVC stands for Polyvinyl Chloride, a type of thermoplastic polymer formed through the polymerization of vinyl chloride (CH2=CHCl), a chemical compound that can be produced from petroleum or natural gas. PVC is one of the most widely produced plastics in the world, with an annual production of approximately 400 million tons.
PVC is extensively used in various fields due to its numerous outstanding advantages:
- High durability: PVC is a thermoplastic material, meaning it can be softened and reshaped without deformation. This characteristic makes PVC an excellent choice for applications that require high durability, such as water pipes, windows, and roofing materials.
- Environmental resilience: PVC is resistant to environmental factors, allowing it to be used outdoors without degradation caused by weather conditions. PVC is also resistant to chemical corrosion, making it suitable for applications involving chemicals.
- Ease of processing and fabrication: PVC can be processed using various methods, including extrusion, injection molding, and calendaring. This versatility makes PVC a flexible choice for a wide range of applications.
- Variety of colors and sizes: PVC can be manufactured in a wide range of colors and sizes, making it suitable for diverse applications.
- Affordability: PVC is a cost-effective plastic, which contributes to its popularity as an economical choice for various applications.

2. Properties of PVC Plastic
PVC plastic is a type of thermoplastic material formed from the polymerization of vinyl chloride. Vinyl chloride is a colorless liquid with a slightly sweet odor and is volatile. The structural formula of PVC is (C2H3Cl)n. Specific properties of PVC include:
- It can be produced in various colors, including white, black, green, blue, red, yellow, and purple.
- The specific gravity of PVC is around 1.4 g/cm3.
- PVC is a highly durable plastic that can withstand temperature, chemicals, and weather impacts.
- PVC's hardness ranges from flexible to rigid, depending on the content of additives.
- PVC is a non-conductive plastic used in various electrical and electronic applications.
- It is resistant to sunlight, UV rays, and does not fade or deform under UV exposure.
- The melting temperature of PVC is up to 140°C.
- PVC is resistant to various chemicals, including acids, bases, and salts.
- It is water-resistant, not absorbing water or undergoing deformation when in contact with water.
PVC plastic exhibits relatively stable chemical properties, not reacting with inorganic substances like acids, bases, and salts. However, PVC can react with organic substances like alcohols, esters, and amines. It can also degrade due to heat, light, and oxidative agents.
When PVC is burned, it releases toxic gasses like dioxins and furans. Dioxins are harmful substances that can cause cancer, birth defects, and other diseases. Furan is another toxic compound that can lead to cancer and other illnesses. Hence, it's essential to use PVC plastic correctly and recycle it after use to minimize environmental pollution and protect human health.

3. How PVC is manufactured?
How Polyvinyl Chloride is made? The PVC production process is a complex one that requires advanced technologies and involves the following steps:
- Raw Material Preparation: The main raw materials for PVC production are petroleum and natural gas. These materials are processed to create basic chemicals like vinyl chloride monomer (VCM).
- Polymerization: VCM is polymerized to form PVC. This process takes place at high temperatures and pressures, resulting in the creation of long chains of PVC molecules.
- Particle Formation: PVC is formed into particles by extruding it through a small hole. The PVC particles are then cooled and stored in a warehouse.
- Molding: The PVC particles are fed through a mold to create PVC products with the desired shape and size.
- Post-Processing: The PVC products undergo post-processing to enhance their properties. This may involve adding lubricants, stabilizers, or other additives to improve the characteristics of the material.

4. Is PVC plastic toxic?
When used and handled correctly, PVC plastic is not harmful. However, prolonged or high-level exposure to PVC can be hazardous. When burned, PVC can release toxic chemicals such as dioxins and furans, which can cause cancer, impact the immune system, and affect reproductive systems.
Chemicals of concern in PVC include:
- Vinyl chloride: This is a known carcinogen. It can be released from PVC when it is burned or deteriorates.
- Phthalates: A group of chemicals that can disrupt endocrine systems and cause reproductive health issues. They are used as plasticizers in PVC to make it softer and more flexible.
- Cadmium: A heavy metal that can be harmful to the nervous system. It can be released from PVC when burned or deteriorated.
These chemicals can also be harmful to animals and the environment. Therefore, it is essential not to burn PVC and to handle it in an environmentally friendly manner.
Here are some tips on using and handling PVC plastic safely:
- Do not burn PVC plastic.
- Do not use PVC plastic for grilling or cooking.
- Do not use PVC plastic to contain hazardous substances, such as pesticides or paints.
- Do not use PVC plastic to store food or beverages.
- Dispose of damaged or old PVC plastic in an environmentally friendly way.
By following these tips, you can help protect your health and the environment.
