A high quality of "220V Cooling Fan" fan, must have a low noise, stable and smooth, and I produced PA66 plastic materials especially for production of fan blades. PA commonly known as nylon, is the general term macromolecular main chain polymers containing repeating units of the amide group. "220V Cooling Fan" is as a flame retardant PA66, glass fiber reinforced, flame retardant glass fiber reinforced, fire-retardant mineral reinforced, mineral salts reinforced, rubber toughened, glass rubber toughening modified plastics raw materials theme, remix Other processing aids MOS2, PTFE and other engineering plastics reinforced composite made appropriate as "220V Cooling Fan" fan.
