What Is PVC? What Is Benefits Of PVC Plastic?

1. The definition of PVC

Polyvinyl chloride (PVC) was one of the first plastics discovered, and is also one of the most extensively used. It is derived from salt (57%) and oil or gas (43%). It is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible.

 

2. Applications of PVC

PVC is widely used in applications such as:

Building products, including window frames and other profiles, floor and wall coverings, roofing sheets, linings for tunnels, swimming-pools and reservoirs.

Piping, including water and sewerage pipes and fittings, and ducts for power and telecommunications.

Coatings, including tarpaulins, rainwear and corrugated metal sheets.

Insulation and sheathing for low voltage power supplies, telecommunications, appliances, and automotive applications.

Packaging, pharmaceuticals, food and confectionery, water and fruit juices, labels, presentation trays.

Automotive applications, including cables, underbody coating and interior trimmings.

Medical products, including blood bags, transfusion tubes and surgical gloves.

Leisure products, including garden hoses, footwear, inflatable pools, tents.

3. Key characteristics of PVC

High density: The density of PVC is 1.38 g/cm3.

Low cost: Economically friendly and affordable.

Good durability: PVC can last up to 40 years.

High strength: High tensile strength (2.6 N/mm2) meaning it takes a lot of force to stretch it out and break it.

Excellent electric insulator: PVC doesn't conduct electricity, making it great for electrical insulation.

Fire-retardant: When PVC catches fire, it slowly extinguishes the fire because it contains chlorine and low oxygen content which combined, isn't good for fire.

 

4. Benefits of PVC plastic

Relatively inexpensive and widely available

Durable

High tensile strength

Insulating

Fire ResistantI

 

Chemical resistant

Because of PVC's structure, it doesn't chemically react with many substances. PVC rarely corrodes or otherwise reacts when it comes into contact with other chemicals and substances such as oils, inorganic acids, fats, salts, bases, and alcohols.

 

5. Disadvantages of PVC

Not all that glitters is gold, and PVC is no exception. There are some downsides to the use of this material, which include:

Environmental concerns

PVC is non-biodegradable, making it an environmental pollutant. It induces land pollution because plastic does not disintegrate. It causes air pollution because when it's burned, it emits dioxin and hydrogen chloride - highly toxic chemicals to the environment.

Health and safety concerns

Because of the toxic chemicals released by PVC during its manufacturing process, use, and disposal, it can be a threat to human health.

Toxins like phthalates and dioxins cause myriad illnesses such as hormonal imbalances, respiratory health effects, and in extreme cases, cancer.

Heat sensitivity

PVC has low thermal stability, making it heat sensitive. When subjected to consistently high levels of heat, it degenerates.
