Sealing strips are often used in our home decoration, so there is no harm in understanding sealing strips. Today, Shanxi sealing strip manufacturers teach you several ways to identify sealing strips:

1. Smell the smell; The compliant sealing strip should be tasteless or have a little taste of natural rubber. If it smells other flavors, it means that it is not a qualified sealing strip and is not suitable for selection.

2, high temperature placement: the sealing strip tightly wrapped in the profile, placed at high temperature for a period of time. Look at whether the contact surface between the profile surface and the sealing strip is stained and discolored, whether the dust on the surface of the sealing strip is yellow and oil seepage, and whether the hands are stained and dirty.

3. Look: Look at whether the brightness and color of the cross section of the rubber strip are close to the surface brightness and color of the sealing strip. If the brightness and surface color are close to each other, it means that the sealing strip does not contain much filler, and the cheap sealing strip will have various fillers, resulting in its surface not being very bright.

4, hand tear. Take a piece of rubber strip and tear it at a thinner part. If you need to use a lot of force, it means that the rubber content is high and its comprehensive performance is good.

5, hand pull. The left and right hands in the hand are pulled outward respectively, first to see if it can be broken, and secondly to see if it can rebound to its original length. The greater the elasticity, the better, and the greater the elasticity, the greater the future installation will not be deformed due to the long-term closing pressure of the door.

6, nail scraping. The surface of the rubber strip with poor material is easily scratched white. After being installed on the door, as long as there is a hard object collision or slight scratch, it will be scratched, which not only affects the aesthetics, but also makes consumers mistakenly think that it is a door material problem, thus causing unnecessary trouble.

7, look at the weight, good sealing strip filling material is not much, the weight is relatively light, some businesses in order to obtain greater benefits, the use of talcum powder, heavy calcium and other things do filler, greatly increased the proportion of the sealing strip products, adding heavy calcium sealing strip, after many times by hand, the surface will appear a small amount of white powder.
