THERMOPLASTIC MATERIALS
The table below provides some brief details
on different thermoplastic materials used in injection moulding. The
list is by no means exhaustive and there are a number of blends of different
materials, e.g. PC/ABS, designed to achieve the best performance properties
of the two individual components. Within each group of plastics materials
different levels of performance are available. Additional strength may
be gained through the addition of fillers, such as talc or glass, in many
cases. Also additives to improve UV stability or flame retardancy or
provide antimicrobial properties may also be used.
