WHAT IS EPDM MULTIPURPOSE HOSE？
First of all, we must know what is EPDM.
The copolymer of ethylene and propylene is generally divided into binary ethylene propylene rubber and tertiary ethylene propylene rubber. It is characterized by excellent ozone resistance, ultraviolet resistance, weather resistance, and aging resistance, and ranks first among general-purpose rubbers. Electrical insulation, chemical resistance, impact elasticity is very good, acid and alkali resistance, and small specific gravity can be a high filler fit. Heat resistance up to 150 ℃, resistance to polar solvents – ketones, esters, etc., but not aliphatic hydrocarbons and aromatic hydrocarbons, other physical and mechanical properties slightly inferior to natural rubber and better than SBR. The disadvantage is that the self-adhesive and mutual adhesion is very poor, and not easy to bond. Use temperature range: about -50℃~+150℃. Mainly used as chemical equipment lining, wire and cable covering, steam hose, heat-resistant transport belt, rubber products for automobiles, and other industrial products.
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 has been widely used in many fields. So what are its advantages over other general-purpose rubbers?
The first is its price/performance ratio. The raw rubber of EPDM (Ethylene Propylene Rubber Hose) is the rubber with the lowest density, and it has the lightest weight under the same volume. In addition, because of its 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 the performance of these fillers on EPDM does not appear. Have a negative impact. And because the cost of pure EPDM is too expensive, these rubbers with fillers and other additives are much cheaper in terms of cost.
The second is its temperature resistance.EPDM products such as EPDM hoses have a temperature resistance of up to 120°C, which means that they can work normally for a long time in this temperature range, for a short time, or indirectly beyond this range. Work in an environment.
Then its corrosion resistance.EPDM rubber is a non-polar rubber, its saturation is very low, it has strong resistance to various acids and alkalis, animal and vegetable oils, refrigerants, etc., and can be used to transport weak acids alkalis, refrigerants, and other materials.
Finally, talk about anti-aging performance. Before talking about the anti-aging performance, we must first know the reasons for aging: the main reason for the aging of rubber tubes and other products is an oxidation reaction, followed by the corrosion of other chemicals such as acid and alkali, and the damage caused by friction. Increasing the temperature can increase the Mars of the oxygen molecules. It is easier for the rubber tube to oxidize. However, EPDM rubber has heat resistance and its saturation is very low, so it can effectively reduce its Oxidation reaction between oxygen, especially ozone.
The above is the reason why EPDM is popular. If you buy hoses, you can come to the Velon factory. We focus on the production of EPDM, NBR, and other rubber industrial hoses.
