Polyvinyl Chloride (PVC)
Polyvinyl Chloride (PVC) is a type of thermoplastic polymer that is widely used in construction, transportation, packaging, and consumer goods industries. PVC is made by combining ethylene and chlorine gas to produce vinyl chloride. Vinyl chloride is then polymerised into polyvinyl chloride, which can then be moulded into a variety of shapes and sizes. PVC has a tough, flexible and durable nature, which makes it suitable for various applications.
Polyvinyl Chloride Usage
PVC is used in a variety of applications due to its versatile properties. Some of the common uses of PVC include:
- Construction: PVC is widely used in the construction industry due to its strength, durability, and ability to withstand extreme weather conditions. It is used in pipes, window frames, roofing, flooring, and other construction applications.
- Healthcare: PVC is used in the healthcare industry for medical devices and equipment such as IV tubing, blood bags, and medical tubing. It is preferred due to its chemical resistance, strength, and low cost.
- Automotive: PVC is used in the automotive industry for interior and exterior applications due to its strength, durability, and resistance to chemicals and weathering. It is used in car interiors, bumpers, and other automotive components.
- Packaging: PVC is used for packaging applications, such as blister packs, clamshell packaging, and other types of packaging due to its clarity, toughness, and barrier properties.
- Electronics: PVC is used in the electronics industry for insulation of wires and cables, and as a sheath for fibre optic cables.
While PVC is a versatile and commonly used plastic, it is also one of the most difficult plastics to recycle. PVC contains harmful chemicals such as lead and cadmium, which can leak into the environment if not properly disposed of. Additionally, PVC products are often mixed with other plastics, making it difficult to separate and recycle.
However, PVC recycling programmes have been developed in recent years to reduce the environmental impact of PVC waste. These programmes focus on collecting PVC products and separating them from other waste streams for proper disposal or recycling. PVC can be recycled into new products such as pipes, decking, and flooring, but the process can be expensive and complex due to the need for specialised facilities and equipment.
Consumers can help reduce the environmental impact of PVC by properly disposing of PVC products and by choosing products made from recycled PVC or alternative materials whenever possible.
