Double Side Copolymer Coated Steel Tape 0.20mm EAA For Optical Fibre Cable
Copolymer Coated steel tape 0.20mm EAA Double Side For Optical Fibre Cable
Measure the advantages and disadvantages of the steel plastic composite tape coating measure is the bonding performance of the composite tape, bonding performance usually refers to three aspects: one is the metal substrate and coated material performance, the second is the bonding performance between the composite tape, the third is the bonding performance of the composite tape and sheath material.At present, the ideal material is ethylene acrylic acid copolymer (EAA) or methyl ethylene acrylic acid copolymer (EMAA), which is a kind of polar material, it can bond with metal very well, but also has a good compatibility with the sheath material, but the price is relatively high.In recent years, with the continuous progress of metal and plastic composite tape technology, hot adhesive film has been developed from the past PE film, EAA(EMAA) monolayer film to today's EAAIPE/EAA /PE/PE structure film.Using this method, it does not affect the adhesive property of the film, but also reduces the production cost.
