In demanding industries such as automotive, aerospace, marine, electronics, and industrial equipment, elastomer materials are required to withstand extreme temperatures, fuels, oils, and harsh chemical environments while maintaining long-term reliability.
Traditional silicone rubber offers excellent temperature resistance and flexibility, but its resistance to fuels and hydrocarbon oils can be limited. To meet the requirements of more challenging applications, IOTA FLSR3400 Series Addition-Cured Liquid Fluorosilicone Rubber provides a high-performance solution combining excellent oil resistance, wide temperature stability, and efficient liquid molding technology.
IOTA FLSR3400 Series is a two-component addition-cured liquid fluorosilicone rubber system. It is based on vinyl-containing fluorosiloxane polymer as the base material and hydrogen-containing fluorosiloxane oligomer as the crosslinking agent.
Through a platinum-catalyzed addition curing system, the material rapidly forms an elastic silicone network without producing curing by-products.
The A/B components are mixed at a 1:1 ratio, providing excellent processing flexibility for injection molding, compression molding, and coating applications.
The outstanding advantage of fluorosilicone rubber is its superior resistance to oils, fuels, and chemical media.
IOTA FLSR3400 Series maintains excellent dimensional stability and mechanical performance after exposure to various fluids, including:
Compared with conventional silicone rubber, fluorosilicone rubber provides significantly improved performance in fuel-contact and oil-resistant applications.
With the unique fluorosilicone molecular structure, IOTA FLSR3400 Series delivers reliable performance under extreme temperature conditions.
Main benefits include:
