Chemical (Resins)
Resins
Resin: “any of various solid or semisolid amorphous fusible flammable natural organic substances that are usually transparent or translucent and yellowish to brown are formed especially in plant secretions are soluble in organic solvents (such as ether) but not in the water, are electrical nonconductors, and are used chiefly in varnishes, printing inks, plastics, and sizes and medicine.”
Types of Resin
Resin can be divided into two types, depending on the nature of synthesis. Resin is of two types:
Natural Resin
These types of Resin have a natural source. They are obtained from nature. Mostly they originate from the plants. Therefore, it is known as plant Resin. It can be isolated by the whole plant, specific part, or exuded by plants because of injury/incision. Rarely, some natural Resin is obtained from the animal.
Synthetic Resin
These types of Resin are produced in the industry. Synthetic Resins are produced by the curing of the rigid polymer. When they undergo a curing process, they contain reactive end groups like epoxides or acrylates.
Resin Chemical Nature
What is in Resin is the most commonly asked question in the polymer Chemistry branch? The answer to this question is, Resin chemically is a complex compound. It is formed by a mixture of various compounds. These are a mixture of essential oils. It can be a mixture of oxygenated products of terpenes (oxygenated hydrocarbons) or it can be a complex mixture of hydrocarbons, acid, ester, and alcohol. They are amorphous or semi-crystalline solids that can be converted into plastic. These chemicals usually have a polymeric or semi-polymeric structure and are either natural or (semi-)synthetic in nature. Before being pelletized, extruded, and moulded into different shapes, they are frequently treated with plasticizers, stabilizers, fillers, antioxidants, and other additives.
