UPVC Profile is widely used, so after a period of use, how can UPVC Profile become white and bright?
Doors and windows are common in UPVC Profile. Plastic-steel windows are a form of window that is actively promoted by the country after wood, iron, and aluminum alloy windows. This is mainly due to its low price and good performance.
The reason why UPVC Profile can be widely used and gradually replaced wooden and aluminum doors and windows is inseparable from its unique advantages. Plastic-steel doors and windows are cheaper than aluminum and wooden doors and windows, and the price of plastic is much lower than that of Aluminum with the same strength and life; durable, reinforced section steel is added to the profile cavity, which greatly improves the strength of the profile, has the effects of earthquake resistance and wind erosion resistance; good thermal insulation performance, the same type of room uses plastic steel doors and windows in the summer The temperature is 5-7℃ lower than the room with aluminum doors and windows on average, and 8-15℃ higher in different areas in winter; the sound insulation performance is good, the plastic steel doors and windows are assembled by welding technology, and the closed multi-cavity structure can shield the noise The effect is very obvious.
UPVC Profile is based on polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, fluorescent brighteners, ultraviolet absorbers, etc., through extrusion molding. Everyone knows that most of our common door and window borders are white, mainly because the white makes the room bright and beautiful. We often encounter this problem, that is, the profile will turn yellow after UV exposure for a period of time. The reason is that the special fluorescent brightener for UPVC Profile is not used.
