5.7. Miscellaneous Uses

• Water storage tanks.

Water storage tanks made from plastics are designed to hold large quantities of water safely and efficiently. Because plastics are resistant to corrosion and rust, they are excellent materials for creating water tanks, which would otherwise deteriorate quickly if made from metals or other materials. Additionally, these tanks are lightweight, making them easier to transport and install.

Imagine a large plastic water bottle you might use at home, but on a much larger scale. Just as a bottle prevents water from leaking or getting contaminated, a plastic water storage tank does the same for much greater volumes, ensuring a clean and safe water supply.

• Cable sheathing and insulation.

In electrical applications, plastic serves as an insulating layer around cables. This sheathing is crucial because it prevents accidental contact with live wires, protecting users from electric shocks. Plastics have excellent electrical insulation properties, which keep the current confined within the wires, ensuring the safe operation of electrical systems.

Think of the rubber coating on your phone charger cable. It protects the wires inside and prevents you from getting shocked if you accidentally touch a metal connection. Similarly, the plastic sheathing around larger electrical cables provide safety by isolating the conductive parts from your touch.

• Construction formwork (reusable plastic shuttering).

In construction, formwork is used to shape concrete when it is poured. Traditionally, wooden or metal materials are used, but reusable plastic shuttering is gaining popularity. This type of formwork is lightweight, flexible, and durable, allowing it to be easily molded into various shapes for different construction needs. Moreover, the reusability of plastic formwork reduces waste and cost over time.

Consider a cake mold that can be reused to make cakes of different shapes multiple times. Similarly, reusable plastic formwork allows builders to create the shapes they need for concrete structures while saving money and resources over repeated use.
