Product Description

Polyimide PI has high and low temperature resistance (-269~400℃), high friction resistance, self-lubrication, high strength, high insulation, radiation resistance, corrosion resistance, small coefficient of thermal expansion, resistance to organic solvents, self-extinguishing, non-toxic, and other comprehensive properties.PI part of the category of long-term working temperature of more than 350 ℃, and short-term can be up to 450 ℃, is the current engineering plastics in the temperature of engineering plastics is better, and its comprehensive performance is unmatched by other special engineering plastics, is widely used in aviation, aerospace, machinery, electrical, atomic energy, microelectronics, thin film, liquid crystal display and other high-tech. Its comprehensive performance is also incomparable to other special engineering plastics, known as the “problem solver”, widely used in aviation, aerospace, machinery, electrical, atomic energy, microelectronics, thin film, liquid crystal display and other high-tech fields.

After years of market cultivation, polyimide as sealing materials, structural materials, heat Insulation Materials, friction materials, high-temperature coatings in the aerospace, military, automotive, compressors, large motors, pumps, tobacco machinery, textile machinery, construction machinery, office machinery, electronic products, mold industry as high temperature, wear-resistant, self-lubricating or sealing parts and components have been widely used, and won a high degree of praise from users. Highly praised by users.

Polyimide Gasket

As a member of high-performance engineering plastics, polyimide PI is not only known for its excellent heat resistance, chemical resistance, excellent mechanical strength and good electrical insulation properties, but also shows its irreplaceable value in the tiny but critical part of gaskets.

Characteristics of polyimide gaskets

Excellent heat resistance: polyimide can maintain stable physical and chemical properties in extreme high temperature environments, long-term use of temperature up to 300 ℃ or more, and even some of the special varieties can work at higher temperatures, which makes it in the high temperature conditions of the sealing application of outstanding performance.

Excellent chemical resistance: almost resistant to all known organic solvents and strong acid and alkali erosion, this feature makes the polyimide gasket in the chemical, petroleum, pharmaceutical and other industries, in the face of complex and changing media environment, still be able to maintain a reliable sealing effect.

Excellent mechanical strength: polyimide gasket has high tensile strength, compression strength and fatigue resistance, can withstand greater pressure and mechanical stress, to ensure long-term stable operation in harsh working conditions.

Good electrical insulation: polyimide gaskets also have excellent electrical insulation properties, suitable for the strict requirements of the electrical performance of the occasion.
