Corrosion Resistant Insulating Paper For Transformer

Model :NDPJ-JYZ-6021

Brief Introduction : We can produce different dimensions of insulation material for stator and armature slot.

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.

We can produce different dimensions of insulation material as per customer's requirement.There are different insulation material, DMD B/F class, Red Polyester film,Class E, Red Vulcanized Fiber, Class A.

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.
