SMC | Sheet Moulding Compound

SMC (Sheet Moulding Compound) is used in hot press compression moulding for the production of large parts with high mechanical properties and excellent surface finish.

SMC is a polymeric composite material, which consists primarily of a thermosetting resin, mineral fillers, and a glass fibre or carbon fibre reinforcement. The resin used is generally unsaturated polyester (UP) or vinyl-ester (VE). Additional ingredients such as thermoplastic components, catalysts, inhibitors, mould release agents, thickeners and colour pigments are used to enhance the performance and moulding process of the final product.

Our Verkid® SMC products come as a sheet 1500 mm wide supplied either on ≈450 kg rolls, on ≈1400 kg MegaRolls, or folded like computer paper in ≈1150 kg boxes.

The transformation or moulding process is carried out in a hot mould at temperatures between 130 – 160ºC and under pressure (typically 30 – 120 bar), in vertical presses specially designed for this process.

SMC applications are wide-ranging in the Automotive & Transportation, Electrical & Energy, Building & Construction, Industrial, Service, Sanitary, Domestic and Medical markets.
