SMC (Sheet Moulding Compound) is a fibre reinforced compound, in a thermoset resin matrix, with mineral fillers and different additives. Generally thermoset unsaturated polyester resins are used as organic matrix. As reinforcement for SMC, both glass fibre or carbon fibre can be used. With the aim of enhancing its characteristics and improve its transformation, other components are added: thermoplastic additives, pigments,demoulding agents, thickeners ,etc. The storage temperature is recommended to be between 5ºC and 25ºC. Higher storage temperatures can significantly reduce the usability time of SMC. SMC is mainly used in hot press compression moulding for the production of manhole cover,drainage grating,floor, bench slat,electric meter box,etc.
