Sheet Moulding Compound
Sheet Moulding Compound (SMC) is a thermoset, glass-fibre reinforced semifinished plastic. VDL Wientjes Emmen produces SMC both for use in its own moulding department and for third parties. In our laboratory we have developed a large number of application-specific formulas, using our many years of expertise. More information about SMC recipees.
Due to an extremely high chemical resistance, strength and temperature resistance, SMC is very suitable for products which have to meet stringent requirements. Its ageing properties are so good that even after many years of outside use with a high UV-load, the mechanical properties of SMC are barely affected. SMC products are impact- and scratch-resistant, colourfast, maintenance-free, temperature- and corrosion-resistant. By adding special additives SMC achieves a high level of flame-retardancy and low waste gas emission.
SMC is composed of resins, glasfibres, pigments, fillers and additives. The SMC slurry is spread on a foil, whereupon the glass fibres are added, which can vary in length and quantity, depending on the required properties and geometry of the product. Then a second layer of slurry is added and covered with foil. Finally, the whole mat is impregnated. Before SMC can be processed, it must be ripened under controlled conditions.
VDL Wientjes Emmen produces SMC for both own use as for third parties with customized specifications and in small series. This way we can adjust flexible to your needs.
