IOTA LSR 3054 Series – Fast Curing Liquid Silicone Rubber with Low Compression Set
Designed for manufacturers seeking both processing efficiency and long-term reliability, the IOTA LSR 3054 Series is a platinum-catalyzed liquid silicone rubber that offers a unique balance of low compression set, fast thermal curing, and excellent mechanical strength. Its two-component system is formulated for a straightforward 1:1 mixing ratio, supporting consistent feeding in high-volume production lines.
The low compression set characteristic of the IOTA LSR 3054 Series ensures that finished parts, such as seals, gaskets, and tubing, can endure continuous compression without permanent deformation. This is critical for applications requiring sustained sealing force over time, including automotive, industrial, and consumer product assemblies.
From a processing standpoint, the material is designed to cure quickly with applied heat, enabling shorter molding cycles. The series also exhibits good mold release behavior, which helps reduce defects and prolongs tool life. Viscosity levels remain moderate across grades (e.g., A-component viscosity ranging from 280 to 380 mPa·s at 23°C, 10s⁻¹), promoting efficient flow into intricate mold cavities.
Cured mechanical properties are application-ready. Higher hardness options, such as LSR 3054-70, provide 70 Shore A, 9 MPa tensile strength, and 340% elongation, suitable for wear-resistant parts. Softer grades, like LSR 3054-20, deliver 20 Shore A with 650% elongation and 7 MPa tensile strength, ideal for flexible sealing lips.
To avoid unwanted cure inhibition, users should follow standard handling practices for platinum-catalyzed systems. Always mix only same-batch A and B components and ensure material uniformity before use. When stored below 23°C, unopened containers maintain performance for up to 12 months. Choose IOTA LSR 3054 Series for durable, low-deformation silicone parts.
