In baby products, food-contact items, and precision sealing applications, material safety and performance are equally critical. The IOTA LSR 3920 A/B series high-transparency liquid silicone rubber rises to the challenge, offering excellent processing properties, superior mechanical strength, and short curing times for demanding applications.

Comprehensive Core Performance
The IOTA LSR 3920 series covers seven hardness grades from Shore A 20 to 77, meeting diverse needs from soft pacifiers to hard sealing components. The product is a two-component transparent liquid with viscosity ranging from 2000 to 5500 Pa·s, suitable for pouring, injection, and coating. Cured tensile strength reaches up to 10.0 MPa, tear strength up to 35 KN/m, and elongation of 330%–900%, achieving an excellent balance between softness and durability. Linear shrinkage is only about 2.0%–2.1%, ensuring dimensional stability and high molding precision.

Safety and Compliance for Baby Care
This series complies with U.S. FDA 21 CFR 177.2600 and German BfR XV regulations, making it safe for food-contact products and baby items. For food-contact use, a two-stage treatment at 200°C for a total of 4 hours is required to ensure purity and no residue. High transparency gives products a clear, transparent appearance, meeting scenarios with stringent visual quality requirements.

Broad Applications, One Material, Many Uses
From baby pacifiers, teethers, and baby tableware accessories, to various sealing gaskets, diving masks and accessories, silicone kitchenware parts, and food-contact sealing rings, IOTA LSR 3920 covers a wide range of high-end applications with good weather resistance, sealing performance, and compliance. Other industrial or consumer applications can also be selected as needed.
