IOTA HTV 329 – Redefining High-Temperature Silicone Rubber
In the world of industrial manufacturing, performance isn't just about meeting standards—it's about exceeding them under pressure. Introducing the IOTA HTV 329 Series, a premium range of high-temperature silicone rubber engineered to perform reliably at extreme conditions up to 350°C. Whether you're producing heat-resistant seals or high-temperature extruded tubing, IOTA HTV 329 is the material of choice for demanding environments.
This series offers excellent processability with compatibility for both compression and extrusion molding. For applications involving food contact, a simple post-curing step at 200°C for four hours ensures full compliance and safety. With hardness options ranging from 40 to 70 Shore A and densities from 1.14 to 1.20 g/cm³, the IOTA HTV 329 Series provides flexibility in design without compromising durability.
Mechanically robust, these grades deliver tensile strengths between 8.5 and 9.5 MPa and exceptional elongation at break—up to 700% in softer grades. Even after 72 hours of thermal aging at 300°C, the material retains impressive integrity, with tensile strengths remaining near 5.0 MPa. That's the kind of resilience your high-heat applications demand.
Choose IOTA HTV 329 for consistent performance, easy processing, and long-term reliability—even when the heat is on.
