It is a mixture of a variety of polymers, so they have different melting points. Resin can be divided into two kinds of natural resin and synthetic resin. Only this kind of natural resin itself, but with the development of chemical industry, there are many from synthetic polymers, among the chemical and physical properties of some polymers and natural resin is very similar, therefore, the polymer is called synthetic resin.
