Engineered for Complexity, Built for Speed – IOTA HTV 312 Series
When your production line demands intricate geometries, fast turnaround, and consistent mechanical performance, the IOTA HTV 312 Series delivers on every front. This high-strength molding silicone gum is specifically formulated for complex parts—kitchenware, swimming accessories, seals, and general molded goods—where flowability, cure efficiency, and finished-part durability are non‑negotiable.
The series offers seven hardness grades, from 20 to 80 Shore A (31220 through 31280), giving engineers the freedom to match material response to application needs. Softer grades provide exceptional elongation—up to 900%—ideal for flexible, thin‑wall components, while higher‑hardness versions deliver dimensional stability and wear resistance for load‑bearing profiles. Across the range, tensile strength stays between 6 and 9 MPa, with tear strength reaching 20 kN/m, ensuring reliable service life under repeated stress or dynamic loading.
Processing efficiency is a hallmark of this compound. With a recommended peroxide (50% bis‑2,4‑dichlorobenzoyl peroxide) addition of just 1.0% and a curing cycle of 5 minutes at 175 °C under 15 MPa pressure, molders achieve fast, repeatable vulcanization without sacrificing green strength or demolding properties. The translucent appearance simplifies visual inspection and color matching, while the consistent plasticity values (100–310) guarantee batch‑to‑batch stability in extrusion or injection molding lines.
Importantly, the IOTA HTV 312 Series meets internationally recognized compliance standards—ROHS, REACH, and FDA—making it suitable for food‑contact and export‑oriented applications without additional regulatory hurdles. Packaged in 20‑kg cartons and stable for 18 months when stored below 50 °C in unopened containers, this material supports just‑in‑time inventory and long‑term project planning.
For manufacturers seeking a balance of cure speed, mechanical robustness, and regulatory peace of mind, the IOTA HTV 312 Series transforms complex part production into a streamlined, predictable process. Backed by typical performance data and supported by technical sales for custom specification development, it is a versatile workhorse for today’s competitive silicone molding industry.
