Whether it is in life or in work, it is inseparable from insulation materials. It not only brings a lot of convenience to our lives, but also plays a key role in the electrical and electrical industry. So what are polymer insulation materials? Which are polymer insulation materials?

Polymer insulation material, also known as polymer dielectric, is mainly used to isolate charged or different potential conductors, so that the current can flow in a certain direction of the polymer material. Its volume resistivity is generally greater than 109 Ω·cm. Most of the polymer materials have excellent insulation properties, a wide variety, a wide range of raw materials, easy processing, and reliable performance, so the application is very extensive.

Polymer insulation materials can be divided into two categories from the use, namely electrical insulation materials and electronic insulation materials, of which electronic insulation materials are mainly used for insulation protection of semiconductor components and their electronic equipment. For example, a printed circuit board often uses resin plates such as epoxy resin plate or phenolic resin plate; the substrate is a polymer film or a single-layer heat-resistant glass varnish, which is made of a polyester, a polyimide, or a fluoropolymer film.

There are also packaging materials, mainly used to prevent the influence of external moisture and impurities on the parameters of semiconductor components. The insulating film for a semiconductor device is a surface protective film and an interlayer insulating film of a semiconductor component such as a large-scale film integrated circuit.

Electrical insulation materials are mainly used for electric motors and electrical appliances, such as insulation of armature wedges, stator windings and rotor windings in generators and motors. According to the shape, it can be divided into six categories, which are known as insulating varnish, resin and adhesive; impregnated fiber products; laminates; plastic products; rubber products.

In fact, we have been exposed to similar products in the past, but we don’t know that they are so-called polymer insulation materials. In fact, insulation materials are really ubiquitous, and our lives will be better because of it, our work will  also become safer.
