Silicone Tabla de Resistencia Química

Silicone (VMQ) Tabla de Resistencia Química

Silicone rubber (VMQ) es conocido por its exceptional rango de temperatura and flexibility. It's FDA-compliant for food contact and ampliamente utilizado in medical, food processing, and high-temperature applications. However, it has limited resistencia química compared to other elastomers.

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

Cuándo Usar Silicone

✅ Excelente Para

• Extreme temperatures (-60°C to +230°C)
• Food and beverage contact (FDA)
• Medical/pharmaceutical applications
• Water and dilute salt solutions
• Ozone and UV exposure
• Electrical insulation

❌ Evitar Con

• Concentrated acids and bases
• Most solvents (acetone, toluene, etc.)
• Fuels and oils
• Steam (causes reversion)
• Abrasive environments (low tear strength)
• Hydrocarbon gases

Silicone vs Viton® vs EPDM

Silicone wins on rango de temperatura and food safety but loses on resistencia química.
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 rango de temperatura.
