As the demand for efficient and reliable sealing solutions continues to grow, understanding the unique properties of different O-ring materials is crucial.
Let’s dive into the key characteristics and applications of three prominent o-ring types:
NBR Nitrile O-Rings:
Working Temperature: Approximately 120°C
Performance Highlights:
– Resistance to oil, heat, wear, solvents and high-pressure oils
– Not suitable for polar solvents like ketones, ozone, and nitro hydrocarbons
Main Application Areas:
– Fuel tanks, lubricating oil tanks
– Petroleum-based hydraulic oil, gasoline, water, grease, silicone oil, ester lubricants, and glycol-based hydraulic oil
VMQ Silicone O-Rings:
Working Temperature: Approximately 220°C
Performance Highlights:
– Environmentally friendly, non-toxic
– Resistance to heat, cold, odor, and atmospheric aging
– Good elasticity and electrical insulation properties
– Lower tensile strength and abrasion resistance compared to general rubber
– Poor oil resistance
Main Application Areas:
– Household electrical appliances
– Food & machinery industry
– Seals for products in contact with the human body
FKM Fluorine O-Rings:
Working Temperature: Approximately 230°C
Performance Highlights:
– Good high-temperature resistance & chemical resistance
– Resistant to most oils and solvents (except ketones and esters)
– Poor cold resistance
Main Application Areas:
– High-temperature, chemical-resistant, and oil-resistant environments
– Metallurgy, chemical industry, automotive, and electric power industries
