Dongguan to the crown Plastic Products Co., said today PU trachea oxygen permeability, pu, as the temperature rises, PU trachea hot oxygen increases. Which we should consider is PU tube has a certain oxygen permeability. PU trachea oxygen permeability and therefore more pronounced. Later, the use of oxygen barrier type PU trachea become the main solution to the problem of gas permeable tube PU, PU trachea application standards in Germany was subject to a hot water pipe at 40 degrees Celsius, the oxygen permeability of not more than 0.1mg / (L · day) , pu pipes and standard detection methods oxygen barrier properties. The production of PU pipe crown with optimal chemical and physical stability, both light and soft, pu trachea, compression, pressure, impact resistance, abrasion resistance, resistance to bending. Corrosion resistance, high temperature, low friction, long life and other characteristics, the tube dimensionally stable, smooth surface, color and diverse, safe and reliable. For the professional production of PU pipe is high-quality companies, Dongguan to the crown Plastic Products Co., Ltd. is a magical presence can not be copied!
