Aluminium Foil Prices
At present, the main composite air ducts on the market are phenolic, polyester and extruded. They are all in the form of embossed aluminum foil on the outer layer and foamed interlayer. These types of ducts do not require any heat preservation treatment. The connection method is all PVC flange connection, this kind of flange has better heat insulation performance, so there is no need for additional heat insulation.
The aluminum foil duct is made of stretched pure aluminum foil, which is continuously tightly clamped through a spiral. Due to the oxidizing nature of aluminum material, a layer of glue is usually applied during production to insulate the aluminum material from the oxidation reaction of oxygen in the air.
The main purpose of the aluminum foil duct is to ventilate the duct at the end of the fresh air system.
The thickness of aluminum foil duct products is generally between 0.08 and 0.2MM, and customers can customize them according to customer needs. According to the size of the spinning tool, theoretically an infinite diameter aluminum foil duct can be made. However, according to the actual application, the inner diameter is generally within the range of 60 to 200MM, and the length is within 10 meters.
Double-sided composite embossed aluminum foil, the sandwich is a plate made of non-combustible phenolic foam insulation board.
The aluminum foil phenolic composite air duct is composed of coated aluminum foil with concave and convex patterns on both sides and sandwiched phenolic foam. The outer coating aluminum foil, its film material is a high-temperature solidified polymer film, which can effectively resist the corrosion of ultraviolet rays and gas, and can not only be firmly combined with the aluminum foil, but also form an interpenetrating network copolymer with phenolic foam. The first choice for processing various direct forming air ducts. The thermal insulation and ventilation ducts made from it are environmentally friendly, heat-insulating and durable, light-weight and energy-saving, safe and non-toxic, beautiful and clean, airtight and soundproof, fire-resistant and waterproof, simple and labor-saving, etc. Excellent performance
