PVC is the abbreviation of polyvinyl chloride, also known as vinyl chloride copolymer. It is a 

commonly used plastic material that is widely used in industrial products, construction materials, and 

medical equipment. PVC has good physical properties, electrical properties and chemical resistance,

making it the material of choice in many fields.

1. Performance of PVC materials

1. Physical properties

PVC is a very durable plastic material with good mechanical properties and stable dimensions. At room

 temperature, PVC is harder than many other plastics, so it is often made into rigid plastic products. The

 hardness of PVC ranges from 15 to 95,and the higher the hardness value, the harder the PVC is. In

addition to rigid PVC, soft PVC has a hardness of approximately less than 85.

2. Electrical properties

PVC is a good electrical insulating material. Its lower operating temperature limit is -15℃ and its upper

 limit is 55℃. It will not explode under the insulation effect and has stable electrical performance, so it 

is widely used in many electrical equipment and cables.

3. Chemical resistance

PVC has good chemical properties such as acid resistance, alkali resistance, oil resistance and ester 

resistance. It is not easily corroded by some basic medicines and various organic solvents, and has strong

 antioxidant properties. PVC is less susceptible to aging, discoloration and brittleness than many plastics.

2. Application of PVC materials

PVC materials are widely used and can be made into various forms of products. The following are several 

applications of PVC.

1. Building materials

PVC is widely used in building materials, such as floors, partition boards, ceilings, etc. Because PVC has 

good hardness, count and toughness, its use in building materials is very popular. Its advantages are 

waterproof, insulation, heat insulation, wear resistance, corrosion resistance and shock absorption. It is

 longer lasting and more energy efficient than many traditional materials.

2. Industrial products

PVC is widely used in various industrial products, such as containers, pipes, bottle caps, bottle stoppers, as 

well as stamping parts, drawn parts and hoops. In industrial products, PVC is widely used, and it has strong 

chemical resistance and is not easily damaged and embrittled by acids, alkalis and other environments.

3. Medical devices

PVC can be used in many medical devices, such as blood transfusion tubes, eye drop bottles, blood bags 

and sacs, dialysis tubes, breathing tubes, etc. PVC has good chemical stability and physical properties and

 can well meet the safety and quality stability requirements of the medical industry.

4. Household items

PVC can be used to make various furniture, curtains, wallpapers, swimming pool protective covers, etc. 

Household products generally have high environmental requirements and require properties such as 

waterproofing, moisture-proofing, and sun protection. PVC is an ideal material that meets the requirements.

           In short, PVC is a very common material in everyone's life. It is widely used in both the industrial 

field and the consumer goods field. PVC has superior performance and a wide range of applications. Its 

materials can also be recycled, which can achieve the goals of saving resources and protecting the

 environment.
