Silicone (VMQ) Chemikalienbeständigkeitstabelle

Silicone rubber (VMQ) ist bekannt für its exceptional Temperaturbereich and flexibility. It's FDA-compliant for food contact and weit verbreitet in medical, food processing, and high-temperature applications. However, it has limited Chemikalienbeständigkeit compared to other elastomers.

Limited data 20°C & 50°C data FDA compliant

Wann verwenden Silicone

Silikon vs Viton® vs EPDM

Silicone wins on Temperaturbereich and food safety but loses on Chemikalienbeständigkeit.
Viton® handles fuels and oils but costs more and isn't food-safe.
EPDM excels with water and steam but can't match silicone's Temperaturbereich.
