Food-Grade Liquid Silicone for Squishy Toys – IOTA LSR 3100 Series
Introducing the IOTA LSR 3100 Series, a premium food-grade liquid silicone developed by IOTA Corporation Ltd. Specifically designed for the production of squishy toys and DIY crafts, this two-component platinum-catalyzed elastomer delivers an ultra-soft, airy texture that is both resilient and satisfying to touch.
The IOTA LSR 3100 Series is formulated to provide an exceptional balance of softness and durability. With a compression set exceeding 30 times its original volume, it offers a unique "air-filled" feel and moderate rebound speed, making it the ideal material for stress-relief toys. The cured product remains dry to the touch, leaving no oily residue, while maintaining a tensile strength elongation rate of over 500%.
One of the standout features of this silicone is its ease of use. It boasts extremely low viscosity and excellent self-degassing properties. After simply mixing the A and B components in a 1:1 ratio, the mixture naturally releases trapped air without the need for specialized vacuum equipment, allowing for a smooth, bubble-free finish. It also demolds easily, making it perfect for both industrial production and home-based DIY projects.
Curing is efficient and adaptable: at room temperature (25°C), the material sets within 2-3 hours, with adjustable curing times available to meet specific production needs. The silicone is also compatible with custom color pastes, offering a semi-transparent base that can be tinted to any shade.
Whether used in automated manufacturing lines or small-batch handmade crafts, the IOTA LSR 3100 Series guarantees consistent performance, a food-grade safety profile, and a luxurious tactile experience—making it the top choice for next-generation squishy toys.
