The spinning method of polyimide film fiber is divided into wet spinning and dry spinning

Thermoset polyimides have excellent thermal stability, chemical resistance, and mechanical properties, and are usually orange in color. The flexural strength of graphite or glass fiber reinforced polyimide can reach 345 MPa, and the flexural modulus can reach 20 GPa. Thermosetting polyimide has low creep and high tensile strength. The temperature range of polyimide is very wide, ranging from minus one hundred degrees to two or three hundred degrees.

6052 polyimide film is an industrialized polymer material with strong heat resistance. Due to its superior comprehensive properties, polyimide films can be widely used in high-tech fields such as films, coatings, plastics, composite materials, adhesives, foamed plastics, fibers, separation films, liquid crystal alignment agents, and photoresists. He was called a "problem solver".

Polyimide film is a new type of high temperature resistant organic polymer film, which is polycondensed by pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in extremely strong solvent dimethylacetamide (DMAC). A film is formed and then aminated. Insulation materials in the world at present. It has excellent mechanical properties, electrical properties, chemical stability, high radiation resistance, high and low temperature resistance (-269°C to +400°C).

In 1959, DuPont first synthesized aromatic polyimide. In 1962, it was trial-produced as a polyimide film (PI film). In 1965, production began under the commodity brand Kapton. In the late 1960s, my country could produce polyimide films in small batches. Has now been widely used in aviation, navigation, spacecraft, rockets and missiles, atomic energy, electrical and electronic fields.

Polyimide is chemically stable. Polyimide prevents combustion without adding flame retardants. Generally polyimides are resistant to chemical solvents such as hydrocarbons, esters, ethers, alcohols and halothanes. They are also resistant to weak acids, but are not recommended for use in strong bases and mineral acid environments. Some polyimides such as CP1 and Corin XLS are solvent soluble, which helps develop their applications in spray coating and low temperature crosslinking. Second, the physical properties of polyimide film

The spinning method of 6052 polyimide film fiber is divided into wet spinning and dry spinning. Depending on whether the spinning slurry is polyimide or polyamic acid, there are one-step spinning and two-step spinning.

Polyamic acid fiber is obtained by wet or dry spinning of a concentrated solution of polyamic acid. The second step is the polyimide fiber obtained by chemical cyclization or thermal cyclization of the polyamic acid fiber spun in the previous step, which is called a two-step method.

Two-step spinning of polyimide fibers has been a widely used method since the development of polyimide fibers.

The drawing process of the fiber can be carried out in the first step, or in the imidization process in the second step, or a certain amount of drawing can be carried out in each step.

The reason why the glued polyimide film is trustworthy, is well used in high-tech products, and is one of the excellent insulating materials in the world, is because it can fully exert its function in the application range, because it can sometimes Works normally at ultra-high temperatures. This can be said to be the many advantages of polyimide tape, which is definitely better than other electronic products. The price definitely affects how it works. In addition, we can also purchase suitable models according to our needs, and compare whether the price is reasonable according to the above information.

Polyimide (PI) is a macromolecular backbone containing imide groups. It is one of the organic polymer materials with better comprehensive properties. It has the characteristics of corrosion resistance, fatigue resistance, wear resistance, impact resistance, low density, low noise, long service life and excellent high and low temperature performance (-269 ℃ ~ 280 ℃ long-term deformation); thermal decomposition temperature can reach 600 ℃, It is one of the varieties with high thermal stability among polymers so far. It has been widely used in aerospace, aviation, aerospace, automobile, microelectronics, nanometer, liquid crystal, separation membrane, laser, electrical appliances, medical equipment, food processing and many other high-tech fields. Known as "Problem Solving Expert" and "Golden Plastic".
