IOTA HTV 329 Series: Superior High-Temperature Silicone Rubber for Demanding Applications
The IOTA HTV 329 series represents a breakthrough in high-temperature performance silicone rubber, specifically engineered to withstand extreme thermal environments up to 350°C. This versatile product line is suitable for both compression and extrusion molding processes, making it an ideal choice for manufacturers requiring reliable materials under intense heat. For applications involving food contact, a simple post-curing process at 200°C for four hours ensures compliance with safety standards.
Key application areas include high-temperature seals and gaskets, as well as durable extruded tubing designed to perform reliably in thermally challenging conditions. The material's excellent thermal stability is complemented by its robust mechanical properties, ensuring longevity and reliability in critical applications.
Available in several grades—IOTA HTV 32940, 32950, 32960, and 32970—the series offers a range of hardness levels from Shore A 40 to 70, allowing for precise selection based on application requirements. Typical properties include impressive tensile strength (up to 9.5 MPa), high elongation at break (up to 700%), and strong tear resistance (up to 25 MPa). Even after extended exposure to 300°C for 72 hours, the material maintains significant mechanical integrity, demonstrating its exceptional heat resistance.
Packaged conveniently in 20 kg boxes, the IOTA HTV 329 series has a shelf life of one year when stored unopened in a cool, dry place. For consistent performance, we recommend use within three months of opening. Trust IOTA HTV 329 for high-temperature applications where failure is not an option.
