Synthetic resins are man-made materials that are primarily used in the production of plastics. They are created through chemical processes that combine various organic compounds, resulting in a solid or semi-solid substance. Common types of synthetic resins include polyester, epoxy, and polyurethane, each with unique properties that make them suitable for different applications. These resins are widely used in industries such as construction, automotive, and electronics due to their durability and resistance to chemicals and heat. They can be molded into various shapes and are often used as adhesives, coatings, and composite materials, enhancing the performance of many products.
