Material density, which refers to the mass per unit volume, plays a crucial role in product design by influencing both weight and strength. High-density materials, such as metals and dense composites, provide strength and durability, making them ideal for structural and load-bearing applications. Conversely, low-density materials, like foams and lightweight plastics, are chosen for applications where reducing weight is critical, such as in packaging or aerospace components. The appropriate density ensures the material meets the design requirements for functionality and efficiency.

Plastic is a synthetic material made from petrochemicals, which are derived from fossil fuels like oil and natural gas. The process of making plastic involves polymerization, where small molecules known as monomers are chemically bonded together to form long chains called polymers. These polymers are then melted and molded into various shapes and forms, creating the plastic products we use daily. Different types of plastics are produced by varying the monomers and additives used in the process.

While plastic offers many advantages, it also has significant disadvantages, particularly in terms of environmental impact. Plastic is not biodegradable, meaning it can take hundreds of years to break down in the environment, leading to long-term pollution. It contributes to the problem of microplastic pollution, where tiny plastic particles enter ecosystems and harm wildlife. Additionally, the production and disposal of plastic generate greenhouse gases, contributing to climate change. Efforts are being made to develop more sustainable alternatives.
