Similarities and differences between NHN and flexible dmd electrical insulation materials and DMDM three types of insulation materials
There are many types of insulation materials, such as NHN insulation materials, flexible dmd electrical insulation materials, and DMDM insulation materials. What they all have in common is that they all have good insulation, but some properties are different, which leads to this Various insulating materials have different applications.
NHN insulating material is characterized by low density, low friction coefficient, small elastic modulus and good corrosion resistance, because it is often used instead of metal to make general structural parts with functions such as transmission, support, buffering, installation, and protection; not only In this way, NHN insulating material can also be used for cooling, heat dissipation, sealing, moisture-proof and solid sealing.
In actual use, NHN insulating material can isolate live parts from non-live parts or live parts with different potentials; of course, it can also play a variety of roles in extinguishing arcs, isolating arcs, or limiting arcs within a certain range.
The obvious difference between DMD insulation materials and flexible dmd electrical insulation materials is their thickness. Although they are all made of polyester film and polyester fiber non-woven fabric, they are bonded with adhesives, but the three-layer It is DM insulating material, and the four-layer one is DMDM insulating material.
From the perspective of performance, both flexible dmd electrical insulation materials and DMDM insulation materials have good mechanical and electrical properties, so they are suitable for slot insulation and gasket insulation of electrical appliances. It should be pointed out that the adhesive used in flexible dmd electrical insulation materials is an acid-free and heat-resistant product, so it can absorb resin when impregnated and is suitable for mechanical end-of-line processes.
