Strength Meets Versatility – The Silicone Platform That Adapts to Your Application
No single silicone fits every product—but the IOTA-HTV 313 Series comes remarkably close. With six hardness options spanning 25 to 70 Shore A, this platform gives designers and process engineers the freedom to tailor material response to specific load cases, flex cycles, and aesthetic requirements—all within a single, proven product family.
For soft‑touch applications like wristbands and protective skins, the 31320 and 31330 grades offer low hardness (25–30 Shore A) with outstanding elongation (800–850 %) and moderate tear strength, ensuring comfortable wear and easy demolding. As part stiffness increases, the 31340 and 31350 grades (40–50 Shore A) deliver a sweet spot of 8 MPa tensile and 30 kN/m tear strength—ideal for structural gaskets and durable housings. At the higher end, the 31360 and 31370 grades (60–70 Shore A) provide rigidity and abrasion resistance for rugged industrial components, while still maintaining 400–500 % elongation.
The processing window is equally broad. The compound’s excellent flow characteristics and consistent plasticity values allow for both compression and transfer molding, with rapid cure times that maximize output. The standard cure recommendation—1.0 % peroxide, 175 °C, 5 minutes—is easy to implement and monitor, reducing the risk of under‑ or over‑cure.
Global compliance is already built in: ROHS, REACH, and FDA certificates support your supply chain requirements, whether you ship to Europe, North America, or Asia. And with a shelf life of 18 months under recommended storage conditions, you can order in economical quantities without waste.
Let the IOTA-HTV 313 Series be your go‑to material for projects that demand reliability, adaptability, and proven performance. Our application engineers are ready to help you select the optimal grade and optimize your molding parameters for first‑time‑right production.
