Answer:

The following properties are typical of "solid" plastics:

  • Low specific gravities
  • Good thermal and electrical resistance
  • Good surface finish directly from the forming dies
  • Availability in a wide color range or transparent if required
  • Low strengths compared to metals
  • Unsuitable for service conditions where temperatures in excess of several hundred degrees centigrade exist
  • Poor to fair dimensional stability, particularly in moist conditions.
