[Abstract]:

1. Tear by hand. You can use a door and window sealing strip to find the thinnest part for tearing. If you need to use force to show that the glue content is high and the overall performance is good, you can consider buying it.

2. Hand pull. Pull the door and window sealing strips by hand to see if they can be broken. In addition, if the elasticity of the sealing strip is better, it means that the sealing strip will not be deformed due to the long-term closing pressure of the door after the sealing strip is installed.

3. Scrape the sealing strip with your nail. You can scratch the sealing strip with your nails to see if the surface is easily scratched, because after the door and window sealing strip is installed, as long as the hard object collides or slightly scratches, it will cause the sealing strip to "broken", which is very unsightly.

4. Observe the sealing strip intuitively. You can observe the cross-section joint of the sealing strip and observe whether the brightness is close to the color of the surface of the sealing strip. If it is close, the quality is better.

5. Smell the seal through the nose. You can smell the door and window sealing strips, high-quality sealing strips are odorless or with a little natural rubber smell.
