Design Properties for Engineers: Key Properties vs. Density of Filled High Performance Polymers

In this blog post, we compare selected design performance properties vs. densities of glass fiber filled high performance polymers.

Glass fiber is the most commonly used filler in high performance polymers. The influence on the properties of polymers by adding glass fibers varies: in PTFE, glass fibers improve mainly the compression and wear properties.

In comparison to unfilled semi-crystalline polymers, glass fiber reinforced materials exhibit increased mechanical strength and higher rigidity. Furthermore, improved creep strength and dimensional stability are achieved by adding glass fibers. In amorphous polymers, glass fibers improve the thermal and mechanical performance, compared to unfilled amorphous polymers, in a limited range.

In the following, the different property figures are shown.
