About the selection of rubber diaphragm materials
Pump valves are widely used in industry, agriculture, and life. The realization of their suction/pressure regulation and throttling functions can be said to be completely dependent on the diaphragm. The use of pump valves is changeable, and different use environments affect rubber membranes. The film has different performance requirements, and the material determines its basic performance. Today we will talk about the performance of different materials for your reference.
EPDM (EPDM), because of its good ozone resistance, aging resistance, and low cost, it is the preferred material for rubber diaphragms, and it has a large share in water pumps and air pumps. In order to make EPDM have more performance, people have successively improved it. For example, in order to make it have good elasticity, flame resistance and other requirements, new improved varieties such as chloroethylene propylene and sulfonated ethylene propylene have been successively produced. , So if we hear manufacturers say that they use EPDM materials to make certain products, it may also be an improved EPDM
Let’s talk about silicone rubber. Its biggest feature is that it is non-toxic and tasteless, and can be in contact with food. Therefore, where rubber diaphragms are needed in drinking fountains, coffee machines and other edible environments, silicone rubber is the first choice.
In addition, silicone rubber can maintain a certain degree of resilience and toughness at a high temperature of 200 ℃. In European and American countries, kitchen utensils made of silicone rubber are very popular, and because it has very little rejection reaction to the human body, it is also used in the medical industry. being widely used
Finally, let’s briefly talk about neoprene and nitrile rubber. Neoprene has good acid and alkali resistance and chemical resistance. It can often be seen in the chemical industry. The biggest advantage of nitrile is oil resistance. It has great advantages when conveying oil materials
Ok, the question about the rubber diaphragm material is simple and popular, and there are many rubber materials, but due to space limitations, we will not talk about it today. If you have any questions or business consultations, please feel free to contact us
