2021-12-09
1, hand tear. You can take 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 comprehensive performance is good, you can consider buying it.
2, hand pull. Pull the door and window sealing strip by hand to see if it 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.
3. Scrape the sealing strip with nails. You can use your fingernails to scratch the sealing strip to see if the surface is easy to be white, 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 "break the image", which is very unsightly.
4. Intuitive observation of the sealing strip. You can observe the joint of the sealing strip section to observe whether the brightness is close to the color of the sealing strip surface. If it is close, the quality is better.
5. Smell the taste of the sealing strip through the nose. You can smell the door and window sealing strip smell, high-quality sealing strip is tasteless or with a little natural rubber smell.
