How many degrees of fluorine rubber resistance?

The high temperature range of fluorine rubber varies due to its molecular structure, formulation and application scenarios. Under normal circumstances, the temperature range of fluorine rubber is between -20 ° C and 200 ° C, which means that in this temperature range, fluorine rubber can maintain good physical properties and chemical stability. The following is a detailed description of the high temperature resistance of fluorine rubber:

First, the conventional high temperature range

Minimum temperature: -20℃ (some special formulations can withstand -60℃)

Maximum temperature: 200℃ (long-term operation)

In this range, fluorine rubber can maintain its original elasticity and sealing properties, suitable for a variety of sealing and connecting parts.

2. High temperature resistance under special formula

Short-term high temperature resistance: Some special formulations of fluorine rubber can withstand high temperatures of up to 220 ° C or even 250 ° C (static seal up to 280 ° C, short-term up to 290 ° C), but such tolerance is usually short term, and may be limited by specific application scenarios and environmental factors.

Extreme high temperature resistance: In rare cases, fluorine rubber may withstand high temperatures close to 300 ° C under extreme conditions (such as extremely high temperatures for a short period of time), but this is usually achieved under special conditions, and may be accompanied by a significant reduction in performance and the release of harmful gases.

Third, safety at high temperatures

Harmful gas release: When fluororubber encounters a high temperature of more than 300 degrees, harmful gases may be released, causing damage to human health. Therefore, when fluorine rubber is used in a high temperature environment, its high temperature resistance and safety need to be fully considered.

Cooling post-treatment: Once the fluoro rubber seal is heated to a high temperature of more than 300 degrees, even after cooling post-treatment may be dangerous, so direct contact with the skin should be avoided.

Iv. Application scenarios

Fluorine rubber because of its excellent high temperature resistance, chemical corrosion resistance and anti-aging properties, is widely used in automobiles, locomotives, diesel engines, fuel systems and chemical plants and other fields, for the production of seals, O-rings and other components.

The high temperature range of fluorine rubber varies according to its formulation and application scenarios. Under conventional conditions, the temperature range of fluorine rubber is -20℃ to 200℃; Under the special formula, its short-term high temperature resistance can reach 220℃ or even higher; However, under extreme high temperature conditions, fluorine rubber may release harmful gases and reduce performance. Therefore, when selecting and using fluororubber, it should be considered comprehensively according to the specific application scenarios and needs.
