Inject Precision, Cure Fast – Simplify Your Fluorosilicone Production
Production speed and process stability are critical in today’s competitive manufacturing landscape. The IOTA FLSR3400 series is a two-component liquid fluorosilicone rubber specifically formulated for injection molding and automated dispensing. With A and B components supplied in a 1:1 mass ratio, mixing is straightforward—whether using a three-roll mill, planetary mixer, or direct injection molding equipment. The platinum addition-cure mechanism ensures rapid crosslinking at moderate temperatures, enabling short cycle times without sacrificing final part quality.
Each grade—FLSR3430, FLSR3440, and FLSR3460—exhibits well-controlled viscosities ranging from 400 to 820 Pa·s (at 10 s⁻¹ shear rate), which ensures excellent flow into complex cavity geometries while minimizing flash and air entrapment. After mixing and degassing, the compound can be molded at 120 °C in just 10 minutes for primary curing, followed by an optional post-cure at 200 °C for 4 hours to unlock the full mechanical potential. This two-step schedule gives processors flexibility: run high-volume production with the primary cure, or add post-curing for demanding applications where compression set and heat resistance are paramount.
The material is supplied in 20 kg cartons, and when stored in a cool, dry environment away from nitrogen-, sulfur-, phosphorus-, or heavy-metal-containing compounds, the original shelf life is 12 months. This stable pot life and predictable cure kinetics reduce scrap and rework, improving overall yield. For manufacturers moving from conventional elastomers to fluorosilicones, the FLSR3400 series offers a smooth transition with proven processing latitude. Streamline your production line, reduce energy consumption, and achieve consistent part-to-part repeatability. IOTA FLSR3400 – designed for the modern injection molding floor.
