MicroFiber High Temperature Glass Wool Insulation Hi-Temp Series

Micro Hi-Temp Micro Hi-Temp glass wool insulation is designed for high-temperature applications up to 350°C, suitable for boilers, ovens, and high-temperature machinery Thermal Conductivity In heat resistance applications, thermal conductivity is crucial. To prevent heat loss, choose insulation with low thermal conductivity – the closer to 0, the better Micro Hi-Temp Thermal Conductivity Table Mean Temperature Thermal Conductivity (W/m.K) 32 kg/m3 40 kg/m3 100 0.046 0.041 150 0.059 0.049 200 0.074 0.058 250 0.098 0.068 300 0.129 0.080 Water Vapor Absorption In industrial heat applications, water and moisture can damage thermal insulation. When water and moisture penetrate insulation, they reduce efficiency and increase weight, potentially causing detachment However, MicroFiber glass wool has been tested for water absorption according to ASTM C411 standard. Test results show water absorption of < 1%, which is very low. When water drops fall on MicroFiber glass wool, they don’t penetrate but form beads on the surface and naturally evaporate Water droplets on glass wool form beads without penetrating the glass wool. Surface Flame Spread NFPA (National Fire Protection Agency) standard NFPA 101 Life Safety Code requires material classification into Class A, B, C, tested according to NFPA 255, ASTM E84, or UL 723 Testing provides two values: Flame-Spread Index (FSI) and Smoke Development Index (SDI), and materials are classified based on these values. Material Classification Table for Surface Fire Spread According to ASTM E84 Flame-Spread Index (FSI) Smoke Development Index (SDI) Class 1 or Class A 0 – 25 450 Maximum Class 2 or Class B 26 – 75 450 Maximum Class 3 or Class C 76 – 200 450 Maximum According to the ASTM E84 surface fire spread classification table, MicroFiber glass wool insulation is classified as Class 1 or Class A with Flame-Spread Index < 25 and Smoke Development Index < 50.
