Rubber cords made of FPM are red. The rubber cords made of this material have a round profile and a standard hardness of 70 ShA. Rubber cords manufactured in this manner can withstand temperatures within the range of -20 to +200 °C. If exposed to the effects of steam a temperature of 140 °C should not be exceeded. Higher temperatures may cause faster wear of the rubber cord resulting in the necessity to replace the rubber cord earlier than usual. Rubber cords are highly resistant to mineral, plant as well as animal oils. These rubber cords are also resistant to certain additives and fuels.
