IOTA-HTV 318 Series: High-Resilience Gas-Phase Silicone Rubber for Premium Elastic Products
The IOTA-HTV 318 series is a high-performance gas-phase silicone rubber engineered for applications demanding exceptional elasticity and superior processing performance. Ideal for manufacturing premium seals, placemats, sports seat cushions, and other high-resilience products, this series ensures outstanding rebound, durability, and compliance with international standards including ROHS, REACH, and LFGB.
Each grade within the series—IOTA-HTV 31830 to 31870—offers a tailored combination of hardness, tensile strength, elongation, and tear resistance to meet diverse design requirements. Hardness ranges from Shore A 30 to 70, with elongation rates from 200% to 550%, ensuring flexibility without compromising strength. The high resilience (50–60% rebound) provides lasting comfort and performance in dynamic applications.
Cured with 1.0% peroxide at 175°C under pressure for 5 minutes, the IOTA-HTV 318 series delivers consistent, reliable results. With semi-transparency, excellent moldability, and stable physical properties, it is the material of choice for brands seeking quality, safety, and elasticity. Available in 20 kg boxes and with an 18-month shelf life under proper storage, this series supports efficient, scalable production for high-end elastic goods.
