Aluminum Mylar Foil for Cable Shield

2018-03-28

Aluminum mylar foil for cable shield is a type of composite foil obtained by coating one side or both sides of aluminum foil with plastic film. Covering the signal delivering wire, mylar foil serves as protector of signals and electric wire. Usually made of aluminum alloy 1145, the foil goes through continuous casting & rolling, cold rolling, separating cutting and complete tempering before being cut into needed lengths and width. Then manufacturers of aluminum mylar foil for cable shield coat the coils with requested colors and send them to cable making factories.

Generally speaking, manufacturers have stricter quality control in length and strength of aluminum mylar foil for cable shield than in surface state. Mylar foil is regarded as qualified as long as there is no oil or holes. However, length must be calculated strictly in processing period. Casting stock must be ten to twelve times longer than requested by clients and another three percent error should be included. This guarantees that the eventual length of the foil will be longer than needed, which makes further processing steps more convenient and easier. As for strength, the industry of aluminum mylar foil for cable shield has a rule saying the strength should be more than 80MPa. After being coated, the foil has to be cut into strips, the width of which can reach as narrow as 12mm. If it’s not strong sufficiently, it cracks easily or leaves rags on the edges. In addition, weak foil may crack while being winded with force around cable wires. Therefore, length and strength must be controlled strictly in production process.

Haomei, professional aluminum supplier with decades of manufacturing experience and over ten years of export history, provide aluminum mylar foil for cable shield of various specifications. Customization is also acceptable. Welcome to contact us at april@aluminumhm.com or wechat/mobile 008615838029491 for more information.
