1. Oil leakage and segregation occur. Waste oil does not dissolve in PVC at all. The appearance of the seal is very simple, showing grease, and the appearance of the outline is also marked with yellow. Even if it is not environmentally friendly, there are many transpiration substances that pollute the air.
2. When the so-called plasticizer sweats or oozes, the seal will lose its original softness, become very hard, and rapidly age and shorten. In this way, some doors and Windows will have large gaps, and the tightness will become very poor (water leakage and dust leakage). In addition, the steel lining in the plastic steel doors and Windows will soon be corroded, many users often find that in the dry season, a large number of red liquid flows from the slats in the window, very dirty, that is, the doors and Windows leak, the steel lining is corroded prematurely, the service life of the doors and Windows will be greatly shortened.
