Engineered for Precision – IOTA LSR 3250HG, The High Tear Strength Liquid Silicone Rubber
When your injection molding application demands both clarity and durability, IOTA LSR 3250HG delivers. This two-component, addition-cure liquid silicone rubber is formulated for high tear strength and fast thermal curing, making it an ideal choice for complex parts, baby bottle nipples, and a wide range of precision-molded components.
Why choose IOTA LSR 3250HG?
With a straightforward 1:1 mix ratio (A:B by weight), this transparent silicone offers excellent processability. At 23°C, the mixed viscosity is 300 Pa·s (ISO3219), ensuring smooth flow and mold filling. After curing at 125±2°C for just 5 minutes, the material achieves outstanding mechanical performance: 50 Shore A hardness (DIN 53505), 10 MPa tensile strength (DIN 53504), 550% elongation, and a high tear strength of 40 kN/m (ASTM D624B).
Reliable and compliant – IOTA LSR 3250HG meets BfR, FDA, and RoHS requirements, supporting use in food contact and sensitive applications. It also provides excellent release properties, reducing cycle time waste and improving productivity.
Storage and usage tips – Store below 23°C in unopened containers for up to 12 months. Always mix components from the same batch number, and stir thoroughly before transferring to your dispensing equipment. As a platinum-catalyzed system, avoid contact with substances that may interfere with catalyst performance.
From everyday seals to geometrically complex injection molded products, IOTA LSR 3250HG combines strength, transparency, and reliability. Contact your IOTA representative to request samples or technical support.
