EPDM rubber is a kind of rubber material that we are familiar with, and it is also one of the general-purpose rubbers. With its excellent oxidation resistance, ozone resistance and corrosion resistance, it is widely used in many fields, such as automotive parts, construction machinery, automotive seals and other fields. So why is EPDM hose so popular? Let the editor bring you to take a look at it in detail:
EPDM hose has the following four characteristics
First. Cost performance.
The raw rubber of EPDM (ethylene propylene diene monomer) rubber is the rubber with the smallest density, and it has the lightest weight under the same volume. In addition, because of its own chemical structure, in the process of making EPDM hose, a certain amount of oil or some other fillers can be added to the material, and these fillers basically have no effect on the performance of EPDM. negative impact. And because the cost of pure EPDM rubber is too expensive, these rubbers with fillers and other additives are much cheaper in terms of cost.
Second, temperature resistance.
EPDM products such as EPDM hoses have a maximum temperature resistance of 120°C, which means that they can work normally for a long time in this temperature range, or exceed this temperature range for a short time or indirectly. work in a wide range of environments. This characteristic makes it often used in applications such as heating pipes for automobiles.
Three, corrosion resistance.
EPDM rubber is a non-polar rubber, its saturation is very low, it has strong tolerance to various acids and alkalis, animal and vegetable oils, refrigerants, etc., and can be used to transport weak acids Alkali, refrigerant and other materials.
Four, anti-aging performance.
Before talking about the anti-aging performance, we must first know the reasons for the burnt flowers: the main reason for the aging of rubber tubes and other products is the oxidation reaction, followed by the corrosion of other chemicals such as acids and alkalis, and the damage caused by friction . Elevating the temperature can increase the sparks of oxygen molecules, making it easier to oxidize rubber tubes, but EPDM rubber has heat resistance, and its saturation is very low, so it can effectively reduce it and Oxidation reaction between oxygen and especially ozone.
