Heat resistance: Melting point: hook surface 230 ℃, matte surface 180 ℃; hook surface 180 ℃ began to soften, 215-220 ℃ began to melt
Cold resistance: below minus 30 ℃ can not be used. In general, the lower the temperature, the stronger the pull, but the lower the durability
Humidity effects: When the humidity reaches 90% RH, the pulling force will be significantly reduced, and can be completely recovered after drying.
