Elevate Your Elastic Products with IOTA-HTV 318 High-Rebound Silicone Rubber
Meet the IOTA-HTV 318 series—a premium gas-phase silicone rubber designed for high-resilience applications such as luxury sealing components, tableware mats, and ergonomic sports cushions. Combining excellent rebound properties with smooth processability, this series passes rigorous safety and environmental tests (ROHS, REACH, LFGB), making it suitable for consumer and industrial products alike.
From soft to firm, the series includes five grades (31830–31870) with hardness levels from 30 to 70 Shore A. All variants maintain high tensile strength (up to 9 MPa), good tear resistance (up to 20 kN/m), and elongation from 200% to 550%, ensuring both flexibility and durability. The consistent rebound rate (50–60%) guarantees long-term shape recovery and user comfort.
Recommended curing with 1% peroxide at 175°C for 5 minutes under pressure, the IOTA-HTV 318 series ensures rapid, reliable vulcanization with repeatable results. Packed in 20 kg boxes and featuring an 18-month shelf life when stored unopened below 50°C, it offers both performance and convenience. Whether upgrading existing products or developing new ones, choose IOTA-HTV 318 for elasticity that lasts.
