seal
Sealant strips are widely used in doors and windows, whether it is the contact between the door and window sash and the frame, or the contact strip between the glass and the fan.
The sealing strip has the functions of shock absorption, elimination, sealing, sound insulation and dustproof, and its function can not be ignored. When choosing a sealing strip for your home's doors and windows, pay attention to the strength, resilience, stretchability and surface gloss of the sealing strip. PVC rubber strips are rarely used. Some of the products are made of unhealthy reclaimed oil (to maintain the softness of plastic PVC). Because the regenerated oil is volatile and has odor, it has an impact on human health. Aluminum is attached, which affects the smoothness of the door and window switch. The door and window glue strips have poor sealing and easy aging, and the service life is only 2-3 years.
EPDM has become synonymous with high-grade sealing strips due to its superior physical properties and good aging resistance.
