From Kitchen to Pool – One Silicone Series That Does It All
Versatility without compromise—that is the promise of the IOTA HTV 312 high‑strength molding gum. Whether you are producing flexible baking mats, durable swim fins, or precision industrial grommets, this seven‑grade series (31220–31280) adapts to your tooling, your cycle time, and your end‑use environment with remarkable consistency.
What sets this series apart is its balanced property profile. At lower hardness (20–40 Shore A), elongation exceeds 650% and tear strength starts at 16 kN/m, giving soft goods excellent flex‑fatigue resistance. Mid‑range grades (50–60 Shore A) offer the sweet spot of 8–9 MPa tensile and 20 kN/m tear, ideal for structural sealing elements. The hardest grade (80 Shore A) maintains 7 MPa tensile with only 150% elongation, providing rigidity for snap‑fit or wear‑surface applications. Density ranges from 1.08 to 1.22 g/cm³, allowing lightweight design without compromising feel or barrier properties.
The processing window is wide and forgiving. Using 1.0% of a 50% active bis‑2,4‑dichlorobenzoyl peroxide catalyst, the compound cures fully in 5 minutes at 175 °C under 15 MPa, producing 2‑mm test plaques with smooth surfaces and minimal flash. This rapid vulcanization reduces cycle times, lowers energy costs, and increases cavity utilization—especially valuable for multi‑impression molds common in houseware and sporting goods production.
Compliance is built in, not bolted on. With ROHS, REACH, and FDA clearances, this silicone allows seamless market access for food‑contact articles and consumer goods in regulated regions. The 20‑kg carton packaging is logistics‑friendly, and the 18‑month shelf life (under 50 °C storage) ensures material freshness across production campaigns.
Whether you are scaling up from prototyping or optimizing an existing molding line, the IOTA HTV 312 Series delivers predictable performance, exceptional finish, and the technical support needed to tailor specifications to your exact part requirements. It is more than a compound—it is a reliable partner in your manufacturing success.
