High-Performance Silicone Solutions: IOTA HTV 329 Series for Extreme Heat Resistance
Step up to the IOTA HTV 329 series, a high-performance silicone rubber crafted to thrive in high-temperature applications up to 350°C. Compatible with compression and extrusion molding techniques, this material is a top choice for engineers and designers seeking reliability under thermal stress. For food-related uses, it can be made compliant through post-curing at 200°C for four hours.
Ideal for manufacturing high-temperature seals and extruded tubing, the IOTA HTV 329 series combines exceptional heat resistance with strong mechanical properties. This ensures that components not only survive but perform optimally in harsh operational environments.
The series includes multiple grades—IOTA HTV 32940, 32950, 32960, and 32970—each characterized by a pale yellow appearance and varying performance metrics. Key parameters such as hardness (Shore A 40-70), tensile strength (up to 9.5 MPa), and elongation at break (up to 700%) provide a wide selection to meet specific application demands. Remarkably, after thermal aging tests at 300°C for 72 hours, the material demonstrates retained functionality, proving its superior endurance.
Packaged in 20 kg boxes, the product has a one-year shelf life under proper storage conditions: cool, dry, and away from sunlight. We recommend usage within three months after opening for best results. When your project demands a silicone rubber that can take the heat, the IOTA HTV 329 series is the intelligent choice.
