In modern cable manufacturing, protecting sensitive conductors and optical fibers from electromagnetic interference (EMI) and moisture ingress is critical for long-term network reliability. Copolymer Coated Aluminium Tape<\/strong> <\/a>(also known as EAA Coated Aluminum Tape or Copolymer Aluminium Tape) from RLB delivers a high-performance, dual-function solution that combines excellent electrical shielding with superior waterproofing and adhesion properties.<\/p>\n

This composite material consists of a high-quality aluminum tape coated on one or both sides with an ethylene acrylic acid (EAA) copolymer layer. It has become an essential component in communication cables, coaxial cables, fiber optic cables, and power cables where both EMI protection and environmental sealing are required.<\/p>\n

What is Copolymer Coated Aluminium Tape?<\/h2>\n

Copolymer Coated Aluminium Tape (also known as EAA Coated Aluminum Tape) is a semi-flexible composite shielding material consisting of a high-purity aluminum foil base coated on one or both sides with an ethylene acrylic acid (EAA) copolymer layer.<\/p>\n

The aluminum layer delivers outstanding electrical conductivity for effective EMI\/RFI shielding, while the EAA copolymer coating ensures excellent heat-seal adhesion to polyethylene cable sheaths (LLDPE, MDPE, HDPE) and forms a robust, long-lasting moisture barrier. This integrated design eliminates the need for separate shielding and waterproofing layers in many cable constructions, simplifying production and improving reliability.<\/p>\n
