Synthetic resin is a kind of artificially synthesized polymer compound, which is a kind of resin that has or exceeds the inherent characteristics of natural resin. ASTM D883-65T defines synthetic resins as solid, semi-solid or pseudo (quasi) solid organic substances of unspecified molecular weight but often of high molecular weight that have a tendency to flow when stressed, often have a softening or melting range and are Shell-shaped.
