Features:
1. High heat preservation efficiency: The fibers of high temperature glass wool are uniform and slender, and the fibers are arranged perpendicular to the heat transfer direction, so that it can effectively prevent heat transfer and reduce heat loss.
2. Strong shock resistance and high durability: The uniform and slender fibers ensure that they are tightly interwoven, which prevents common insulation materials from being shaken or stretched due to fiber disconnection after a period of use, resulting in voids and heat conduction. The phenomenon that the loss increases with the use time.
3. Lightweight material and easy installation: The light-weight high-temperature glass wool is extremely easy to install, and it can be cut into any size according to requirements with ordinary paper cutters during construction.
4. Chemical properties: The pH value of high-temperature glass wool is between 7-8, and its soluble chloride ion content is very small, and it has no corrosive effect on equipment and pipelines.
5. Strong Hydrophobicity: High-temperature glass wool is composed of slender glass fibers and does not contain slag balls. Compared with other types of insulation materials, it will not break due to water or rain, and its insulation performance will not change after drying.
