Due to steadily increasing requirements for cable protection, insulation and screening in industry. Gujarat polymer offers a complete assortment for flexible tapes suited to these requirements.

Polyester film is very excellent choice for cable industries for power cables, submersible, fiber, optic and jelly filled cables, due to its dielectric and insulating property, excellent mechanical and tensile strength, tear resistance and shear strength. Apart from this it also has low moisture absorption property and fungus resistance properties. Copper corrosion is also negligible. Polyester film melts at high temperatures at 255�C and shrinkage % are very low. Polyester film in normal conditions are unaffected by ageing.

Due to excellence electrical insulating properties, flexibility and ease of handling on coating machines, this film is used for interphase insulation and as a core wrap for power cables and underground cable. Polyester film alone or along with aluminum foil and other substrates from the composites and used in cable industry for different application. Polyester film or laminates composites is used for pair shielding in coaxial cables, instrumentation cables, aircraft cables, data transmission cables and LAN cables. It is also used as a protective wrapping electromagnetic or electrostatic interference. The section of material is depended on specific needs for each cable and application.

Polyester film alone and its composites are used for its dielectric insulation property while its cables are laid for its perfectly insulated electrical property and laid along term uses and required barrier properties like water vapor transmission, cables which are exposed to high which are exposed to high temperatures. Theses cables are used in public buildings, subways, trains, factories, aviation and electrical installation, petroleum filled jelly cables offshore cables, power cables, CATV trunk cable, coaxial cables. Polyester film alone or aluminum foil and other substrate of different thickness are used depending on specific needs and application.

For maximum safety and efficiency the right cables have to be used and the right cables have to be used and the right connections are to be made at all times. Polyester film can be used alone as color coded tapes for an easy identification. All installation must be faultlessly wired and errors in connections must be avoided. Code printed tapes allows us to identify each conductor. Name of the manufacturer can be also printed on this tapes. Polyester film printed and laminated with heat polymers can be used for flat cables, jumper cables, fiber optic cables, identification and binding tapes for multi pair cables.
