SYNTHETIC RUBBER APPLICATIONS on Aircraft Engines 440175
LABORATORY testing of synthetic rubber vulcanizates typical of those available for use on aircraft engines revealed that:
- 1.Synthetic rubber stocks vary greatly both in percentages and rates of weight loss during aging at 212 F.
- 2.Changes in physical properties of the stocks tested during oil aging are a function of both the temperature of testing and of the aniline point of the oil.
- 3.Gum extracted by aromatic fuel from synthetic rubber stocks varies with the temperature and, to a much smaller extent, with the length of time of extraction.
- 4.X-ray diffraction analysis provides a means of identifying some of the polymers and crystalline fillers in a stock, and also yields information regarding the particle size of the fillers present.
