Dow SILASTIC EFX60MLC10 Fluorosilicone Compound – Frequently Asked Questions (FAQ)

Q1: What are the primary performance advantages of EFX60MLC10 compared to standard silicone elastomers?

A: EFX60MLC10 offers significantly enhanced resistance to fuels, oils, and polar solvents—such as aviation kerosene, hydraulic fluids, and chlorinated hydrocarbons—while retaining the broad temperature range, compression set resistance, and low-temperature flexibility characteristic of fluorosilicones. It is especially suited for dynamic sealing applications where both chemical exposure and thermal cycling are present.

Q2: Is EFX60MLC10 suitable for aerospace or automotive fuel system components?

A: Yes—EFX60MLC10 is formulated to meet demanding requirements in aerospace and high-performance automotive applications, including O-rings, gaskets, and diaphragms exposed to jet fuels (e.g., JP-8), synthetic lubricants, and aggressive brake fluids. Its fluorosilicone chemistry provides a balanced profile of fluid resistance, mechanical integrity, and long-term stability under vibration and thermal stress.

Q3: How is EFX60MLC10 typically processed, and what curing systems are recommended?

A: EFX60MLC10 is a two-part, platinum-catalyzed liquid silicone rubber (LSR) designed for injection molding and transfer molding. It requires precise metering and mixing of Part A (base) and Part B (catalyst), followed by heat-curing at elevated temperatures. Post-cure is generally recommended to optimize physical properties and extractables profile, particularly for critical sealing applications.

Q4: Does EFX60MLC10 comply with FDA or USP Class VI requirements for medical use?

A: EFX60MLC10 is not specifically formulated or certified for direct food-contact or implantable medical applications. While fluorosilicones may be used in certain non-implantable medical device housings or fluid-handling components, end-use compliance depends on full system validation—including processing conditions, post-cure protocols, and finished part testing—against applicable regulatory standards.
