Plastic
What is Plastic?
Plastic is a synthetic material made from a wide range of organic polymers. It is typically derived from petrochemicals and can be molded into various shapes. Plastics are known for their versatility, durability, and resistance to degradation, making them suitable for a vast array of applications. The properties of plastic vary greatly depending on the specific polymer used, influencing its color, hardness, density, and other characteristics.
