Thermal Management Made Simple – Choose IOTA-HTV 330 for Reliable Conductivity
Designing for heat control doesn’t have to mean sacrificing mechanical properties or complicating your production line. The IOTA-HTV 330 Series of thermally conductive silicone rubbers offers a practical, proven solution for manufacturers of thermal tapes, pads, and custom-molded components.
With seven distinct grades—from 33030 to 33080—this series gives you a clear choice based on hardness, flow behavior, and thermal efficiency. The Williams plasticity values range from 30 to 79, while thermal conductivity increases steadily from 0.5 up to 2.0 W/(m·K). Density varies between 1.0 and 2.5 g/cm³ depending on the filler system, allowing you to balance weight, cost, and heat transfer performance.
Mechanical robustness is not an afterthought: tensile strength remains high across the board, and tear strength holds steady at 0.8–0.9 MPa, ensuring durability during assembly and in-service use. The DBPMH cure system delivers excellent heat aging resistance, making these materials suitable for long-term applications where thermal cycling is common.
We understand that production efficiency matters. The IOTA-HTV 330 series processes cleanly in compression molding, with fast cure response and minimal mold fouling. Our recommended cure conditions—175°C for 5 minutes at 15 MPa with 1% curative—are easy to integrate into existing manufacturing workflows.
All grades are produced with strict quality controls and meet RoHS and REACH standards, so you can confidently ship your finished products into regulated markets. Packaging is designed for shop-floor convenience: 20 kg per carton, with clear labeling and batch traceability.
Storage is simple—keep unopened cartons in a dry, cool environment away from sunlight, and the material stays stable for up to one year. Even if stored longer, a simple remilling step restores its processing characteristics.
