Corrosion Resistant Insulating Paper For Transformer

Product Description:

Motor film is a high-grade film made of polyethylene terephthalate as raw material and special polyester masterbatch mixed in a certain proportion, and then dried, melted, extruded, cast and stretched vertically and horizontally.

 

Application of 6021 insulating paper:

Blister, folding box, packaging, printing, card making, high and mid-range tapes, labels, office supplies, collar linings, electronics, insulation, flexible circuit printing, monitor screensavers, membrane switches, film windows, printed films, Imposition film base, self-adhesive backing paper, glue coating, silicon coating, motor gasket, cable tape, instrument panel, capacitor insulation, furniture stripping film, window film, protective film inkjet printing, decoration, printing film base, advertising film Base, digital inkjet, magnetic card, light box, tape leader, IC card, signage, composite, printing, gluing, coated glass, reflective sheet, electronic board, die-cutting, printing industry, packaging industry, advertising industry, electronic industry, etc. The application is very wide.

 

advantage:
1. The color is uniform, the surface is smooth and flat, and the color does not fade.
2. Odorless, tasteless, non-toxic, smooth surface, good flexibility, no water ripples on the surface, no crystal points, no double phase whitening, good impact resistance strength (good impact resistance strength at low temperature).
3. Corrosion resistance, excellent insulation, excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, small thickness tolerance, low thermal shrinkage rate, firmness, low shrinkage, low water absorption, smooth and shiny surface , Creep resistance, fatigue resistance, friction resistance, dimensional stability are very good, high temperature and low temperature resistance, high chemical resistance, oil resistance, good air tightness and fragrance retention, and is also a commonly used barrier property One of the composite film substrates.
