The word “Resin" literally means "fat from trees," but in reality, the term “Resin" is used to refer to a wide range of plant-derived substances that have properties similar to fat. There are two types of resins: natural resins and synthetic resins. Natural resins ⇒ Refined sap collected from plants. Synthetic resins ⇒ Synthesized from petroleum-based chemicals.
Synthetic resins, which are inexpensive and have a stable supply, are often used as raw materials for industrial applications. Synthetic resins include plastics, polyethylene, acrylics, etc., and are often used for household products, construction materials, vehicle bodies, etc., taking advantage of their plasticity (the property to deform when force is applied), which is one of their characteristics.
