In the field of fire protection, material performance directly determines the reliability of the safety defense line. An addition-cure silicone material developed specifically for high-strength fire-resistant cloth, with outstanding performance, has become a core driving force for improving the quality of fire-resistant cloth, building a stronger safety barrier for various protection scenarios.
The most prominent advantage of this material lies in its "combination of rigidity and flexibility" in protective properties. The white protective layer formed after curing has moderate hardness—it will not be brittle like hard plastic, nor lose support due to being too soft. Test data shows that it can withstand a tensile strength of 5.5MPa, equivalent to bearing 55 kilograms of pull per square centimeter, and can maintain structural stability even in high-temperature environments. An elongation rate of 250% endows it with excellent flexibility, allowing it to stretch with the deformation of the cloth, avoiding cracking caused by excessive rigidity. Moreover, a tear resistance of 16KN/m ensures it will not be easily damaged in emergency situations.
For production enterprises, construction convenience directly affects production efficiency. The material has excellent "shaping wisdom"—thixotropy. During construction, it can easily and evenly cover the surface of glass fiber cloth through scraping or dipping; after stopping operation, it can quickly set without flowing, significantly reducing material waste and rework costs. More importantly, it has extremely strong adhesion to glass fiber cloth, and can closely bond with the cloth after curing without delamination or falling off, improving product qualification rates from the source.
The use and operation are also convenient and efficient. The material adopts an A/B two-component design, which can be used after mixing in a 1:1 weight ratio without complex measuring tools. The mixed material has stable viscosity, which can adapt to different coating equipment and ensure production continuity. Storage conditions are also very friendly: unopened products can be stored for 12 months at temperatures below 23℃, with clear labels on the packaging indicating the best use date. Even if it exceeds the shelf life, it can still be used after passing performance testing, providing flexibility for enterprise inventory management.
In addition to its core application in fire-resistant cloth, this material also performs excellently in products requiring scraping or dipping processes, such as industrial pipeline protection and equipment heat insulation sleeves. With stable flame retardancy and protective performance, it has become an ideal choice for safety upgrading in multiple fields.
