Top 10 EPDM O-Rings Manufacturers and Suppliers in China (2024)
In this article, you will learn how to filter out the huge number of manufacturers and suppliers to select the one offering the best products. Moreover, you will also get an overview of the ten EPDM manufacturers in China that offer the best services along with high-quality products.
An Overview Of the EPDM O-Rings Industry
EPDM O-rings are made from Ethylene Propylene Diene Monomer, a terpolymer of ethylene and propylene. The purpose of EPDM O-rings is to prevent leakage in joints, similar to other O-rings. They possess features such as resistance to a wide range of temperatures, acids, alkalis, chemicals, ozone, steam, sunlight, and abrasions.
Metal-detectable EPDM O-rings are also available, which are particularly useful in the food and beverage industries. Regular EPDM O-rings are beneficial across various sectors, including automobiles, electronics, and water systems. The demand for EPDM O-rings has surged due to their unique features, making them a preferred choice over traditional rubber seals.
