According to the era of new material last night announcement, the company placement fund raising 365 million yuan to build high-performance insulation structure industrialization projects, that is, with an annual output of 500 tons of polyimide film production line, successfully produced qualified products, and has begun volume Availability.
Announcement shows that polyimide film products, high technical barriers, large profit margins, the market prospects.New wood using chemical imine (CIM) production of polyimide film products close to the performance of similar foreign products, small quantities of products Delivered to customers after the trial qualified, the product can achieve import substitution, while optimizing the company's industrial structure.
Times New Materials is working hard to develop new production line expansion plans and plans to address the current market demand for the product in short supply.
Encyclopedia: What is the stuff of polyimide?
Polyimide English name Polyimide, referred to as PI. Polyimide film, including both benzene-based polyimide film and biphenyl polyimide film two types.
Application areas
film: Polyimide film is one of the earliest polyimide products used in motor slot insulation and cable wrapping materials. Transparent polyimide film can be used as a soft solar cell substrate. At present, the only solar sail that Japan IKAROS (Icarus) sail is made of polyimide film and fiber.
coating: Used as insulating paint for magnet wire or as a high temperature paint.
Advanced composite materials: for aerospace, aircraft and rocket components is one of the most high temperature structural materials.For example, the United States plans for the supersonic airliner designed speed of 2.4M, flight surface temperature of 177 ℃, the required life of 60000H, it has been reported that 50% of the structural materials have been identified as carbon fiber reinforced composites based on thermoplastic polyimide as a matrix resin with an approximate use of 30 tons per aircraft.
fiber: Second only to the elastic modulus of carbon fiber, as high temperature media and radioactive materials and bullet-proof filter material, fire-retardant fabric.
Foam: For high temperature insulation materials.
Engineering plastics : Thermoset and thermoplastic, thermoplastic can be molded or injection molded or transfer molded, mainly for self-lubricating, sealing, insulating and structural materials.
Separation membrane: For a variety of gas pairs, such as hydrogen / nitrogen, nitrogen / oxygen, carbon dioxide / nitrogen or methane separation, but also as a pervaporation membrane and ultrafiltration membrane.
Electronic Components and Semiconductor Industry
Photoresist: Certain polyimides can also be used as photoresists, negative and positive matrices with sub-micron resolution, and pigments or dyes for color filters that greatly simplify the manufacturing process.
Applications in Microelectronic Devices: As a dielectric layer for interlayer insulation, as a buffer layer can reduce stress and improve yield. As a protective layer can reduce the environmental impact of the device. The semiconductor industry uses polyimide as a high temperature adhesive, can play the metal layer And a variety of external environment isolation.
Orientation aligning agent for liquid crystal display: Polyimide occupies a very important position in TN-LCD, SHN-LCD, TFT-CD and alignment material of ferroelectric liquid crystal display in the future.
Electricity -Light material: Used as optical switch material of passive or active waveguide materials, fluorine-containing polyimide is transparent in the communication wavelength range, and using polyimide as chromophore matrix can improve the stability of materials.
Humidity sensitive material: Using its principle of hygroscopic linear expansion can be used to make humidity sensor.
