Compression moulding industrial application

Compounds are short (/w 0.3 mm) or long (> 0.6 mm) fibre reinforced thermoplastic or thermoset polymeric materials, which are processed automatically (injection or compression moulding), have good (mechanical) properties (for automotive, electric and electronic applications) and are relatively cheap. Composites contain continuous fibres (rovings, fabrics or mats), usually combined with thermosets, have excellent mechanical (structural) properties, but are very expensive because lack of an industrial process (mainly used in aerospace and aircraft industry). 

A Class B, zero shrink, high reacitivty polyester resin designed to be compression moulded at 137 - 155 C, as in the manufacture and use of fast cure sheet moulding compounds. Finds automotive as well as structural/industrial applications. 

These polymers can be moulded by injection or compression and can be cast as films fi om organic solvents. Their isotropic tensile moduli are well beyond the range of known isotropic polymers. They have outstanding mechanical properties, considerably better than those of the best polymeric materials, and can even be compared to structural metals [66] (see Mechanical properties). The rigid PPP backbone is presented as the microscopic equivalent of the fibre in a fibre-polymer composite, such as oriented carbon fibres embedded in a suitable polymer matrix the pendant groups play the role of the suitable polymer matrix. Applications in the design and construction of military and commercial aircraft, sports and industrial equipment and automobile components are proposed.
