In our daily lives, the use of sealing strips can be seen almost everywhere, including on cars, doors and windows, and commonly used machines. Among them, Window seal has the functions of waterproof, sealing, sound insulation, dustproof, heat preservation and energy saving. It has strong tensile strength, good elasticity and high temperature resistance. So do you know how to distinguish its quality? Let’s follow the EPDM sponge strip editor for a brief look!
One, the identification method of high-quality category
1. Smell the smell. Use your nose to smell the window seal we bought for any peculiar smell, the normal material will have a slight mellow smell.
2. Look at the profile. Wrap the window seal tightly on the profile as much as possible and leave it at high temperature for a period of time to confirm whether the surface of the profile and the contact surface of the sealing strip is stained or discolored, whether the dust on the surface of the sealing strip seeps yellow, and whether there is dirt on the hands.
3. Look at the proportion. The quality of high-quality Window seals is lighter than that of inferior ones, and the white powder will appear when the inferior seal strips with heavy calcium are placed by hand.
2. Harm of poor quality
Inferior Window seals are not only environmentally friendly, but the peculiar smell contained in them can also cause harm to our bodies, pollute the air, and reduce airtightness. Poor quality sealants may also contain inferior plasticizers or their substitutes, which are prone to aging and hardening in winter, creating gaps, causing water leakage or dust leakage. This will not only corrode the steel lining after water enters between the window and the sealing tape, but will also greatly reduce the aesthetics.
The above is an introduction by the editor of EPDM sponge strip: How to distinguish between good and bad window seal quality, I hope you can learn more about it.
