The European company Astar is specialized in formulating and manufacturing SMC, BMC and CSMC thermoset compounds for moulders and OEMs. Astar has been developing for more than 55 years custom-made formulations in order to deliver high quality solutions for each specific application and end market.
SMC, BMC and CSMC thermoset materials are based on unsaturated polyester (UP), vinyl-ester (VE) or epoxy (E) resins, fillers, and glass fibre or carbon fibre reinforcement. Other ingredients such as catalysts, stabilizers, mould release agents, thickeners, pigments and specific additives are used to enhance its properties and facilitate transformation or moulding process according to particular requirements.
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.
BMC | BULK MOULDING COMPOUND
BMC (Bulk Moulding Compound) can be moulded both in injection or compression process for large-scale production of medium-size or small complex parts.
CSMC | CARBON FIBER SMC
CSMC combines the lightweight properties of carbon composites with a well known manufacturing process, as compression moulding, that allows fast manufacturing and thus is suitable for high volume industrial applications.
