Technical Detail

A thermo-plastic engineered and environment-friendly film, the Polyester Film is ideal for slot liners, closures and inter-phase insulation in electric motors, fans, generators, transformers and other major electronic & electrical components. It has the features of high level of safety & reliability.

The Polyester Films are also applicable in Copper Insulation, Cable Wrapping, OHP Sheet, FRP Sheets, Packaging, Industrial Film, Optical Displays, Lamination, Window Packing, Printed Electronics, Stationers, Labels, Stickers and more. We manufacture and distribute this innovative multipurpose product as per current industry trends.

Product Quality:

1) Insulation Resistance: The Polyester Film has a high degree of insulation resistance and good electrical properties. Also it has a very low rate of moisture absorption. This product is recommended for slot liners in HP and FHP ratings, in various electrical rotating systems.
2) Toughness: The films do not crack or split when sharply creased. They are easily formed into Cuffed slot closures and liners, by using semi-automatic machines. It works effectively in fully-automatic inserting & forming machines.
3) Ageing: Our top-grade polyester film has a longer life span than its general grades. It is effectively calculated by conducting Accelerated Ageing Tests at super high temperatures.
4) Chemical Compatibility: The Polyester Films provided by us are compatible with many impregnating varnishes, especially those that are based on isophthalate / terephthalate type polyester resins.
5) Brittleness: The films can be utilized at temperature of -70 degree Celcius, and without become brittle.

Some extra film improvements that can be practical during the manufacturing of polyester films cover:

1) Use of chemical treatments for better adhesion to various coatings, adhesives & inks.
2) Addition of fillers and pigments for translucency, haze or opacity.
3) Smooth texture surface can be modified to attain desired roughness.
4) Custom finishes are also achieved by co-extruding with various polyester layers.
5) Custom-made to meet a desirable product performance specifications.
6) Surface-slip, anti-stat, anti-fog, anti-glare properties can be integrated.
