Introduction about technical requirement of the use of copolymer coated aluminum tape
Dec 12, 2017

In fact, when research and analyze the use of copolymer coated aluminum tape, the quality of raw materials should be considered first. The copolymer coated aluminum tape mainly consists of two parts, aluminum tape and plastic layer. When select the aluminum tape, it must be combined with the requirement to ensure that the thickness tolerance is not more than 8 %.

In general, when produce copolymer coated aluminum tape, for the choice of the plastic layer, low-density ethylene resin is usually chosen for production, also note that heavy film material and high quality coating material should be chosen, when produce it, a layer of copolymer resin that meets the standard requirements can be placed between the polyethylene plastic layer and the aluminum tape to ensure the quality of the copolymer coated aluminum tape.

In addition, the appearance quality of the copolymer coated aluminum tape also has a strict standard, normally, the surface of the copolymer coated aluminum tape should be kept flat , smooth, even, without impurities, folds and spots, and there is no obvious mechanical damage and defects. Otherwise, it will affect the quality of copolymer coated aluminum tape. The side of copolymer coated aluminum tape which was cut should be protected by plastic film which was two millimeters to five millimeters. The side should be flat, without edge curl, notch and burr.

Meanwhile, the size, color and packaging of the copolymer coated aluminum tape also need to comply with relevant regulations. In order to guarantee the requirements of copolymer coated aluminum tape, during the inspection of copolymer coated aluminum tape, the mechanical and physical properties, dielectric properties, filling compound resistance and corrosion resistance should be tested.

In addition to these requirements, it is also important to ensure that the winding mode of the copolymer coated aluminum tape should conforms to relevant standards. Normally, the copolymer coated aluminum tape should be tightly wound round the steel or aluminum core pipe whose inner diameter is 204mm plus or minus 3mm, outer diameter is 225mm plus or minus 5mm. As long as meet these requirements, the use of copolymer coated aluminum tape can be improved.http://www.copolymercoatedaluminumtape.com/
