Plastic is a synthetic or semi-synthetic polymeric material that can be moulded or shaped, usually by applying heat and pressure. It is used across almost every sector, from packaging and construction to textiles, electronics, transportation, and healthcare. Its desirable properties include durability, low cost, ease of production, lightweight flexibility, and non-conductivity. Plastic's versatility has led to its widespread use, with about 50 kg of plastic produced annually per person worldwide, and production doubling every ten years. However, this very versatility has also led to significant environmental issues, with an estimated 8 to 12 million tons of plastic entering oceans annually and contributing to pollution and ecosystem degradation.

Plastic is used for electronics and electricals
Plastic is used across almost every sector, including packaging, construction, textiles, transportation, and electrical and electronic applications.
Plastics are polymeric materials that can be moulded or shaped, usually by applying heat and pressure. This property of plasticity, often combined with other desirable characteristics, allows plastics to be made into a wide range of products.
Plastics are widely used in electrical systems and electronics due to their unique thermal properties and electrical insulation capabilities. Polyethylene (PE), for instance, is a popular choice for electrical applications because of its high dielectric strength and excellent insulation properties. It is suitable for cable and wire insulation, insulating bushings, and transformer components. PE also offers resistance to electrical arcing and corona discharge, reducing the risk of electrical breakdowns and prolonging the lifespan of electrical parts.
Polypropylene (PP) is another plastic with high electrical insulation performance and dimensional stability, making it a reliable option for electrical systems operating in high-temperature and challenging environments. Its high melting point, chemical resistance, and low moisture absorption further contribute to its suitability for electrical applications such as capacitors, battery casings, and switches.
ABS, a three-part thermoplastic polymer, is used for electrical enclosures, housings, and connectors due to its impact resistance and mechanical strength. ABS also offers good chemical and flame resistance, making it ideal for use in hazardous locations.
Polyamide (PA), commonly known as nylon, is valued for its excellent mechanical strength and heat resistance. PA is often used as an insulating material for electrical connectors, switches, and circuit breakers. Its ability to maintain its shape and strength under demanding conditions enhances the safety and performance of electrical components.
The electrical and electronics industries benefit from the versatility of plastics, utilising their mouldability, thermal properties, and insulation qualities to create a range of products, from cable insulation to battery casings.

Plastic is used in transportation
Plastic is used in almost every sector, including transportation. In 1998, around 390 kilotonnes of plastic were used in transport applications in the UK, and this number increases every year.
Plastics are used in transportation because of their durability, heat resistance, impact resistance, and lightweight nature. They are also moisture-resistant and do not corrode or warp. Plastics require less maintenance than other traditional materials to remain in good condition. They are also cheaper and easier to clean.
Plastics are used in the flooring of many mass transit applications. Thermoplastics are the most common choice for floor panels because they are durable, can withstand high temperatures and constant foot traffic, and have non-slip features.
Plastics are also used in mirrors and other reflective surfaces in transportation. Acrylic is a better option than traditional glass for mirrors. Transparent polycarbonate thermoplastics are used in windows and windshields because they are stronger and more impact-resistant than glass. Plastic glazing places a protective layer over the glass, so passengers are not hit with shards in the case of an accident.
Plastics are also used in signage, which is critical in transportation. Plastic signage is cheaper, lasts longer, withstands the weather, and is easy to clean.
