  2. To avoid direct sunlight for a long time, too strong sunlight is fatal to the aging of rubber. Rubber is generally black and has strong heat absorption capacity, so it will cause the temperature to rise, thereby changing its physical properties, and the direct result is softening. .

  3. Avoid high temperature environment. As mentioned above, direct sunlight will cause high temperature deformation. Another harm of high temperature is that it will cause the rubber to melt.

  What are the identification methods of timing window seals from China?
