Product Description
The design and manufacture of EPDM rubber O-Rings need to follow strict standards such as AS568, ISO3601, etc. to ensure dimensional accuracy and material consistency. During the manufacturing process, the rubber undergoes steps such as compounding, extrusion, moulding and vulcanisation to achieve the required mechanical strength and sealing properties.
Material Properties:
WEATHER RESISTANCE: EPDM rubber is resistant to UV rays, ozone and extreme weather conditions
Heat resistance: EPDM can withstand a wide range of temperatures, typically between -50°C and +150°C
Chemical Resistance: Good resistance to a wide range of liquids, including water, steam, lye and some acids
Low water absorption: EPDM's low water absorption rate makes it ideal, especially in wet or flooded environments.
Electrical insulation: Good electrical insulation properties make it suitable for use in electrical systems.
Types of O-Rings:
- Silicone O-Ring: Ideal for temperature swings, dry heat, and UV weathering.
- EPDM O-Ring: Resistant to alcohol and solvents, suitable for various applications.
- Neoprene O-Ring: Perfect for heat exchangers and chiller systems.
- Nitrile O-Ring: Popular for oil and fuel resistance.
- Clear O-Ring: Used in medical and food processing industries.
- Metal O-Ring: Strong and corrosion-resistant for diverse applications.
- Metric O-Ring: Specified using the metric system, widely used globally.
- As a leading factory in China, we are proud to offer a wide range of material o-rings that meet industry standards.
