nature : Resin a major categories. After a heated softened (or melting) after solidification and cooling becomes insoluble state of melting resin. Due to the heat and catalysts or heat and under pressure, chemical reactions and become hard. The general shape after forming polymers. Heating not softened. Strong thermal decomposition were damaged. For example, phenolic resin, amino resin, epoxy resin, unsaturated polyester resin.
