Polypropylene modified by the addition of reinforcements
such as talc, chalk, mica and glass fibre has enabled it
to establish itself as a metal substitute in engineering
applications. Further sophistication involving
development of coupling systems, impact modifiers and
technology for improved surface finish has more recently
led to rapid growth of second generation grades in areas
traditionally dominated by other engineering plastics
such as ABS, Polyamide, modified PPO, Polyester, Acetal
and Polycarbonate. |
