Defy Extreme Heat: IOTA HTV 329 Series – Silicone That Performs at 350°C
When the environment turns hostile and temperatures soar, standard elastomers fail. The IOTA HTV 329 Series is engineered for the relentless – a high-temperature silicone rubber that maintains structural integrity and mechanical performance even at 350°C. Whether you're molding critical sealing components or extruding heat-resistant tubing, this material is built to outlast conventional silicones under prolonged thermal stress.
What sets the IOTA HTV 329 apart is its balanced property profile. Available in hardness grades from 40 to 70 Shore A, it offers tensile strengths up to 9.5 MPa and elongation at break ranging from 400% to 700%, giving designers flexibility for both rigid and resilient parts. Even after 72 hours at 300°C, the material retains remarkable performance – hardness shifts are minimal, tensile strength stays above 4.9 MPa, and elongation remains practical for real-world applications. These figures aren't theoretical; they come from standardized testing with 0.6% DBPMH peroxide under controlled curing conditions.
Beyond numbers, this silicone delivers processability. It suits compression and extrusion molding, with a recommended post-cure at 200°C for food-contact applications. Packaged in 20 kg cartons and stable for 12 months when stored cool and dry, it's a reliable choice for engineers who demand consistency. The IOTA HTV 329 doesn't just handle heat – it turns extreme temperatures into an everyday advantage. For prototypes or production, this series bridges the gap between high-temperature resistance and dependable mechanical strength.
