Menzolit Sheet Moulding Compound PDF Print E-mail

Fibre reinforced polyester systems in the form of Sheet Moulding Compound (SMC) are moulded into various parts in a lot of application areas. Typically these are automotive, electrical, construction and sanitary due to their excellent performance regarding heat stability, mechanical and electrical properties.

The systems are custom – made to all kinds of needs by changing the basic formulation. Central focus is always the application:

Preparation and manufacturing

Preparing the resin paste is one of the key processes.
The various liquids and powders are mixed under high shear forces.
Basic raw materials are resins, additives, catalysts, mould release agents and fillers. For coloured compounds a pigment is added to the paste.
The paste is then mixed with fibres, usually glass fibres. This happens on a continuous line for SMC. On the SMC line the doctor box delivers the paste onto the carrier film. On top of the paste a layer of chopped glass-fibres is added by the cutter. Then paste is metered on a second film and fed on top of the glass fibres to form a sandwich of paste – fibres – paste. The sandwich is treated by rollers to impregnate the fibres with the two paste layers. Then the sheet is wound into a coil. Finally Menzolit SMC is maturated to a leather like sheet and ready for removing the film and customizing the size to be moulded.
