Fibre reinforced polyester systems in the form of Bulk Moulding Compound (BMC) are injection moulded into various parts in a lot of application areas. Typically these are automotive headlamps and electrical devices as well as engine parts 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. BMC is prepared in a mixer. After preparing a base paste it will be loaded into the mixing device. Then all other ingredients are added and homogenized. The compound is packed into bags until moulding. To avoid any material changes during storage and transport it is packaged in a styrene tight packaging.
