A marble resin is a polymeric product (natural, artificial or synthetic) that is a basic material for the manufacture of plastics, textiles, paints (liquid or powder), adhesives, varnishes, polymer foams, etc. It can be thermoplastic or thermosetting.
A solid or semi-fluid, vitreous, flammable, water-insoluble, yellow or brown-coloured organic substance, spontaneous or induced exudation of certain plants, particularly conifers and terebinthaceous plants (this substance extracted from pine and fir).
We don’t say « plastics »anymore, we say « resin. »
In a reinforced plastic material, marble resin, also known as a matrix, is a very fluid or highly viscous matrix, used as a binder to make contact between the various reinforcing particles, such as fibres, balls or microspheres (small spherical geometry particle with a diameter of the order of one micrometer[between 1 µm and 1 mm]. The micro-spheres are sometimes called « micro-particles » or « microbead » of glass.
For example, SMC (Sheet Moulding Compound) prepregs include polyester resin, reinforcement (matt, fabric or fibre), fillers and a pre-mixed catalyst (hardener). This ready-moulded mixture for hot compression molding is in sheet form.
Since the term « plastic » has a pejorative connotation for some consumers, the word « resin » is often used by manufacturers in place of « plastic » and marble resin follows the same logic.
The SPI coding system for the identification of resins is a code developed in 1988 by the Society of the Plastics Industry to facilitate the sorting and recycling of plastic bottles and containers.
It is adopted in Germany as DIN 6120, then in Europe, and is applied voluntarily by manufacturers, but must nevertheless comply with a precise codification in accordance with a European Commission decision of 28 January 1997 (97/129/EC).
