Synthetic resin is a kind of synthetic 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 with unrestricted molecular weight but often high molecular weight. They have a tendency to flow under stress, often have a softening or melting range, and when they break It is shell-shaped.
In practical applications, it is often used synonymously with polymers or even plastics, especially the basic materials produced by monomer polymerization without any additives or with only a very small amount of additives. In addition, it is sometimes used to represent uncured fluid thermosetting polymer materials.
The world's three major synthetic materials include synthetic resin, synthetic rubber and synthetic fiber. Synthetic resin is the synthetic material with the highest output and consumption.
