Summary: New silicone formulation achieves long-term stability at 300°C, expanding applications in aerospace and industrial furnaces.
Detailed Content:
Traditional food-grade silicone typically withstands temperatures from -40°C to 230°C, limiting use in extreme high-temperature environments. In 2026, Chinese manufacturers achieve a significant technological breakthrough by modifying molecular cross-linking structures and adding specialized heat stabilizers, developing a new silicone grade stable at 300°C for continuous use. In thermal cycling tests, the material exhibits 40% lower degradation rates than conventional high-temperature silicone, extending service life in harsh conditions. This breakthrough enables new applications in aerospace engine components, industrial furnace seals, and high-temperature conveyor belts. Hongye Silicone’s R&D team has mastered this technology, offering customized 300°C-resistant silicone rubber and LSR products for industrial clients.
