Sealing strip is a product that seals a thing so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. So do you know how to distinguish good from bad? The editor of Sponge sealing strip profile will give you a brief introduction.
1. Use your nose to smell if there is any peculiar smell. Normal PVC material will have a little bit of mellow smell, which is almost invisible.
2. Wrap the sealing strip on the profile as tightly as possible, and place it under high temperature for a period of time (on the roof or in a sunny place). Check whether the surface of the profile and the contact surface of the sealing strip is stained or discolored, whether the dust on the surface of the sealing strip is yellow (the oil is easy to absorb soil), and whether the hands are dirty.
3. There are a lot of fillers for some cheaper sealing strips, so the surface will not be very shiny, and those that are cheap and not shiny are not advisable.
The above is the editor of Sponge sealing strip profile introducing how to distinguish good from bad for sealing strips. I hope you can learn more about it.
