There are significant differences between Viton rubber sheets and silicone sheets in terms of performance and application, mainly in terms of temperature resistance, chemical stability and areas of application.
Temperature resistance
Viton rubber sheet and silicone sheet both have good high temperature resistance, but the working temperature range of the two are different, Viton rubber sheet can be in the temperature range of -20 ° C to 250 ° C stable work, a short period of time can also withstand higher temperatures. Silicone sheets, on the other hand, have a much wider operating temperature range of -60°C to 230°C, making them particularly suitable for use in low-temperature environments. As a result, silicone sheets perform better in extreme cold and lower temperature applications, whereas Viton rubber is more suitable for use in high temperature and high pressure conditions.
Chemical stability
Viton rubber sheets excel in chemical resistance, especially against petroleum, fuels, acids and alkalis, and other chemicals. Silicone rubber sheets are more resistant to mild chemicals such as weak acids and alkalis, but do not perform as well as Viton when exposed to strong corrosive substances; therefore, Viton rubber sheets are usually used in highly corrosive environments such as chemicals and petroleum, whereas silicone rubber sheets are commonly used in food processing and medical equipment because of their non-toxicity and hygienic properties.
Areas of application
Due to its high temperature and chemical resistance, Viton rubber sheet is mainly used as seals and gaskets in automotive, aerospace, petrochemical and other fields. Silicone rubber sheet, on the other hand, with its wide temperature resistance, non-toxic and odourless characteristics, is more often used in medical, food processing, electronics and other industries.
To sum up, Viton rubber sheets are suitable for high temperature and more corrosive applications, while silicone sheets take the lead in daily and industrial applications with their versatility and safety.
