Polyimide prevents combustion without adding flame retardants.
2022-02-14 11:27:32

6052 polyimide film has stable chemical properties. 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.

Polytetrafluoroethylene film is made of polytetrafluoroethylene resin through molding, sintering, cooling, turning and calendering. The turned film is a non-oriented film, and the non-oriented film becomes an oriented film after rolling, and the non-oriented film is 1.1-1.8 times of the semi-oriented film. Films are used as conductor insulating capacitor dielectrics.

Electrical instrument insulation, sealing gaskets have high crystallinity, tight molecular orientation, and small porosity, so PTFE film has been greatly improved. PTFE film is divided into PTFE color film, PTFE activated film and F46 film. A certain amount of colorant is molded and sintered into a blank, and then turned and rolled into a 13-color PTFE directional or non-directional color film of red, green, blue, yellow, purple, brown, black, orange, and white. Adding a certain amount of colorant to the polytetrafluoroethylene color film still has good electrical insulation. It is suitable for insulation, classification and identification of wires, cables and electrical parts.

Polyimide film

Although a certain amount of colorant is added to the PTFE color filter, it still has good electrical insulation. It is suitable for adding bronze powder to insulation and classification identification products of wires, cables and electrical parts. After the activation treatment, the performance is further improved. It can be compounded with rubber and metal, and can also make special tapes that meet the design requirements. It is widely used in light industry, military industry, aerospace, oil field and other fields. F46 film has the most remarkable pressure resistance performance.

Adhesive polyimide film is also a type of tape, but its overall function has been greatly improved. First, it is a foreign production technology. Not only do we not admit that it is really difficult to reach the same level at home and abroad in various industrial technologies. This film tape shows its advantages when used, which is beyond the reach of many domestic products.

Because of this, more users also use this tape. What are the advantages of using it? First, better sealing can be achieved in use. We all know that the main function of tape is to seal. If you can't get good results, it can't be called a product. Some domestic products cannot be sealed in all aspects.
