Coated polymide film is composed of diamine diphenyl ether (DDE) and pyromellitic dianhydride (PMDA) after polycondensation in a very polar solvent, filming process and imidization. There are uniaxial stretching and biaxial stretching, and the made film is called polymide film, also known as gold film. It has no poison, and can be used safely.

Due to the excellent combination of electrical properties, heat resistance, chemical resistance and high mechanical strength, polymide film is enabled with high performance, reliability and durability to withstand extreme temperatures, vibrations and other demanding environment, becoming the industry standard. It is widely used various industries, such as consumer electronics, photovoltaic and wind power generation, aerospace, automobile and various industrial applications.

Many countries are now studying the related technologies. Polyimide is so hot, mainly due to:

1. Polyimide is a high-tech products, and its applications are extremely high-end and broad;

2. After the successful launch of new products into the market, we generally can get a higher profit;

3. Polyimide has been widely used in military and aerospace.

So if anyone can do better or can be connected, he can better reflect and obtain the corresponding value (this is also the reasons that some colleges and business is willing to develop this product).

There are many classification methods for polyimide special engineering plastic, this article only discusses polyimide used as engineering plastics, and explains only according to the physical structure characteristics and chemical structure characteristics.

According to its physical properties, polyimide can be divided into crystalline and amorphous. Most of the polyimide is non-crystalline, with only few structural polyimide is crystalline and semi-crystalline. The crystalline form has a distinct melting point, and has a relatively low melt viscosity and processability above the melting point. So it is the preferred structure type for the development of thermoplastic polyimides. Non-crystalline polyimide has no melting point, the melt viscosity is still high when above the glass transition temperature (Tg) , so molding is generally adopted.
