Injection Molded Fluorosilicone Grades Comparison
Fluorosilicone is chosen for injection-molded parts when exceptional resistance to extreme temperatures, fuels, and chemicals is required. To select the suitable grade, consider factors like temperature range, exposure to fuels or oils, and specific chemical resistance requirements.
High-temperature fluorosilicone suits extreme heat, while fuel-resistant or oil-resistant grades are ideal for parts exposed to these substances. Aerospace-grade fluorosilicone meets stringent aerospace standards and is essential for critical aircraft components. The choice depends on the specific environmental and performance demands of the application.
