Lightweight
The specific gravity of plastics ranges between 0.94 and approximately 2.4, meaning they weigh only about 1/12 to 1/3 as much as metals when compared by weight.
Material | Phenol (SD) | PTFE (PT) | PTFE (PTN) | UHMWPE (PE) | PEEK (PK) | PP (PP) |
Weight | 1.4 g | 2.1 g | 2.14~2.2 g | 0.94 g | 1.3 g | 0.9 g |
Therefore, given the same volume, plastic components are inevitably lighter than metal components. This leads to a reduction in the load on various components, including the shaft, making the design more compact.
In aircraft, such as drones, where heavy materials cannot be used for individual components, plastic is the ideal material.
Comparison: A metal bearing labeled 6004 made of high-carbon chromium steel weighs approximately 69g. In contrast, the plastic bearing with the following compositions weighs:
