The sealing strip product is non-toxic, environmentally friendly, resistant to aging and high temperatures, and has stable performance. It can maintain good performance in both summer and winter

1. Steel skeleton composite, not easily deformed or contracted, assembled firmly, with good sealing performance:

2. Sealing strips are used for doors, windows, and curtain walls. The product has good elasticity, migration resistance, and can effectively isolate noise, prevent dust, and weather.

Performance and hazards of inferior sealing strips:

1. There is a phenomenon of surface oil leakage and precipitation. The waste engine oil used in the rubber strip is not compatible with PVC, and the surface of the sealing strip is prone to grease. Yellow marks are also stained on the surface of the profile, which is not environmentally friendly and contains many volatile substances that pollute the air.

2. When the so-called plasticizers evaporate or seep out, the sealing strip will lose its original softness, become very hard, and quickly age and shrink, resulting in a large gap in the sealed part of the doors and windows, and poor sealing performance (such as water leakage and dust leakage). Especially in the steel village of plastic steel door merchants, it will be quickly corroded. Many users often find that a lot of red thick material flows out from the pressure strip part of the window during the rainy season, which is very dirty. That is, the steel lining of the doors and windows will be corroded too early, and the service life of the doors and windows will be greatly reduced
