Introduction of quality related parameters for the use of aluminum plastic composite belt
Apr 18, 2018

The application of aluminum plastic composite belt is widely applied in modern communication optical cable and communication cable. Generally speaking, when judging the quality of aluminum plastic composite belt, it is mainly judged by several parameter indicators.

 

1. Mechanical properties:

For the aluminum plastic composite belt, its mechanical properties are mainly judged according to the three indexes, which are tensile strength, RP0.2 (non proportionate extension strength) and elongation at break. In fact, these indicators are mainly determined by the metal baseband used for the aluminum plastic composite belt, reflecting the performance of the baseband. Usually, the tensile strength of the high quality aluminum plastic composite belt can reach 97.56Mpa and RP0.2 (non proportional elongation strength) to 70.84Mpa, and the elongation at break reaches 32.74%.

 

2. Adhesive properties:

 

The so-called bonding performance usually refers to the peel strength of the aluminum plastic composite strip, that is, the index to measure the bonding performance between the aluminum plastic composite belt and the base film. The bonding properties of the aluminum plastic composite belt are mainly related to the properties of the materials used in the film, which are related to the manufacturing level of the manufacturers and the quality of the metal baseband. From the analysis of the test data, the products with excellent performance are imported chromium plated steel baseband, high quality cable aluminum base belt, and their copolymers and their technological level are excellent.

 

3. Compatibility:

 

Due to the practical application of aluminum-plastic composite strip, it needs long-term contact with ointment in optical cable. Therefore, in order to ensure its service life, we should also consider its compatibility with ointment. The test of the resistance to fill complex is to observe in the ointment, where the metal base band and the copolymer film will not be bubbling or stratified, that is, to examine the compatibility of the use of the aluminum plastic composite belt and the cable filled ointment.

 

In addition to the above indicators, when judging the quality of the aluminum plastic composite strip, we should also take into account its corrosion resistance and dielectric properties. The corrosion resistance mainly means that the aluminum plastic composite belt is used in the acid or alkaline environment. The polymer film and the metal base band will not be stratified and will not cause corrosion to the metal base band.http://www.copolymercoatedaluminumtape.com/
