Industrial Resins and Bio-resins

Theory

The Resin can be defined as an organic product, solid or semi-solid, with natural or synthetic origin, without a precise melting point and, usually, with a high molecular weight.

Many resins are polymers, the main distinction to be done is between thermoplastic resins and thermosetting:

• The thermoplastic are linear or ramified polymers that can be melted giving them the right quantity of heat; during the plasticization phase they do not go through variations on the chemical point of view;
• The thermosetting resins are very hard materials composed by grid polymers in which the polymeric chains motion is strongly limited by the high number of existing cross-linking. During the transformation phase they pass through an irreversible chemical transformation.

The material typically used for the industrial bio-resins production are:
