Structural PVC, or Polyvinyl Chloride, is a plastic material widely used in the construction industry due to its durability, resistance to environmental elements, and versatility. It is renowned for being lightweight yet strong, making it an excellent choice for a range of applications from piping and window frames to fencing and decking. Structural PVC is also low maintenance, as it does not corrode, rust, or require painting, providing a long-lasting solution. Furthermore, its properties allow for energy-efficient insulation when used in windows or doors. However, one must consider its environmental impact, as PVC production and disposal pose concerns. Innovations in recycling and manufacturing processes aim to mitigate these issues, making structural PVC an increasingly sustainable option.

Polypropylene plastic, known for its versatility, strength, and resistance to chemicals, heat, and water, is widely used across various industries. Common applications include packaging for consumer products, such as containers and bottles, due to its food-safe properties. In the automotive sector, it's utilized in car parts for its lightweight and durable nature, improving fuel efficiency. Additionally, polypropylene is a popular choice for manufacturing textiles (e.g., ropes, thermal underwear) because of its moisture-wicking abilities. It's also used in medical devices and packaging because of its sterilizable characteristic. Its adaptability to different manufacturing techniques, such as injection molding and extrusion, further expands its range of applications, making it a fundamental material in everyday products and specialized applications alike.

Titanium dioxide is a commonly utilized ingredient in the production of various items such as paints. sunscreens. cosmetics and food coloring. This is due to its renowned ability to scatter light and provide brightness. However. there is some debate surrounding its potential health hazards when consumed or inhaled excessively. To mitigate these concerns. it is advised for consumers to thoroughly research the products they use and ensure they meet safety standards. The European Food Safety Authority EFSA establishes daily intake limits for foods containing titanium dioxide as a precautionary measure.
