Discussion on how to distinguish between high quality high-temperature resistant casing by manufacturer of emergency repair belt
First, when we receive the heat-resistant casing, we first take out a piece and observe its surface silicone coating. The high-quality heat-resistant sleeve has a generally smooth surface, no impurities, no papules, bubbles, scratches, etc..
Secondly, it is observed that the color of the internal glass fiber knitting tube is normal white or milky white and light yellow, and the internal glass fiber is prepared more regularly and there is no disorder phenomenon.
You can also try to use a lighter or spray gun for testing. In the experimental test, after a 10-15 minute open fire burns, the surface silica gel is carbonized, but there is no significant change in the internal glass fiber. High quality high temperature casing working temperature 260 degrees, instantaneous temperature up to 1650 degrees. When encountered with continuous high temperature or open fire, it can protect the safe and normal use of cable, pipeline, wire harness and other equipment.
