These information and data presented here, both general facts and property values are for use as references only.
Data based on test specimen evaluations have great practical value, but you can only be completely assured of design and product integrity by producing and testing prototype parts – in the actual proposed conditions of fabrication and service.
The densities of some commonly used thermoplastic are:
ABS: about 1.05g/cm³
HDPE: about 0.96g/cm³
PC: about 1.20g/cm³
PS: about 1.05g/cm³
Nylon: about 1.15g/cm³
Some engineering thermoplastics have densities higher than that of polycarbonate. Polybutylene terephthalate (PBT) has a density of 1.30g/cm³. Acetal, polysulphone and polyethylene terephthalate (PET) have densities of about 1.40g/cm³.
Table below shows the density and specific volume of some representative thermoplastics.
