1. Judging from appearance
observe whether the surface of the strip is bright, clean and beautiful, without serrated marks. Filling soft PVC sealing strip has rough surface, no light and large deformation. In summer, door and window rubber steal strip is the contact surface with the profile dirty and discolored, yellow and oily.
2. Judging from hand feeling
it feels delicate and soft when touched by hand. It is moderately stretched without breaking. After bending, it can quickly restore its original shape and has good elasticity. The strength of filled PVC sealing strip is poor, it will break once folded and crack once pulled.
3. Judging from the smell
the high-quality sealing strip is made of EPDM rubber. The nose smells no peculiar smell, which is green, environment-friendly and pollution-free. However, the inferior sealing strip not only has strong peculiar smell, but also has strong irritation, which is harmful to human body. This sealing strip will soon become hard and brittle, and cannot achieve the sealing effect.
I believe everyone knows the harm of inferior sealant strips, which we can avoid. We should pay attention to these when buying doors and windows in the future; you can also check whether the sealing strip of your own aluminum alloy doors and windows is qualified, and give yourself a safe, environmentally friendly and worry-free home.
