EPDM is one of the general rubbers. With its excellent oxidation resistance, ozone resistance and corrosion resistance, it is widely used in many fields, such as automotive parts, engineering machinery, automotive seals and other fields. So what are its advantages compared with other general rubbers?
First of all, its cost performance
EPDM raw rubber is the rubber with the lowest density. Therefore, it has the lightest weight under the same volume. In addition, due to its own chemical structure, in the process of making EPDM hoses, a certain amount of oil or some other fillers can be added to the material. And these fillers basically have no negative effect on the performance of EPDM. Because the cost of pure EPDM is too expensive, these rubbers with fillers and other additives are much cheaper in terms of cost.
Secondly, its temperature resistance
EPDM hoses have a maximum temperature resistance of 120℃. That is to say, it can work normally for a long time in this temperature range. Or it can work in an environment beyond this range for a short time or indirectly. This feature makes it often used in applications such as car heater pipes.
Then it is its corrosion resistance
EPDM is a non-polar rubber with a very low saturation. Therefore, it has strong tolerance to various acids, alkalis, animal and vegetable oils, refrigerants, etc.
Finally, let’s talk about anti-aging performance
The main reason for the aging of rubber tubes and other products is oxidation reaction. The second is the corrosion of other chemicals such as acids and alkalis, as well as the damage caused by friction. Increasing the temperature can increase the sparks of oxygen molecules, making it easier for rubber tubes to oxidize. However, EPDM has heat resistance and its saturation is very low. Therefore, it can more effectively reduce its oxidation reaction with oxygen, especially ozone.
