Project details

O-ring EPDM refers to an O-ring made of ethylene and propylene copolymer, which typically has excellent heat resistance, aging resistance, ozone resistance, stability, and other characteristics. This material is very suitable for sealing and water blocking, and can work normally in the temperature range of -50 ° C to+150 ° C.

In addition, the O-ring EPDM also has good weather resistance and ozone resistance, which can be used outdoors for a long time. Its water resistance and chemical resistance are also very good, which can prevent water and chemical erosion. Therefore, it is widely used for sealing and waterproofing in automotive engine systems, doors and windows, bearings, and other fields.

It should be noted that O-ring EPDM is not suitable for food use or exposure to aromatic hydrogen. In addition, due to its soft material, it is not suitable for use in high pressure environments.

Overall, O-ring EPDM is an excellent sealing material with extensive applications in industrial and commercial fields.
