What is pi? Polyimide resin (PI) is a raw material with high temperature resistance and wear resistance.

One-stop supplier of special plastics solutions-Ye Zi, a manufacturer of special plastics in Zheng Hao, reveals your secrets:

Polyimide materials (chemically called polyimides) are manufactured in standard blank shapes for processing and are produced in the form of plates, rods and tubes. In addition to the sintering process used to produce blanks, the direct molding process can also be used to produce finished parts on a large scale in a cost-effective manner.

PI plastic is a kind of high temperature polymer that will not melt. Even at the temperature above 260℃, the strength, dimensional stability and creep resistance are still very high. Low wear rate, working ability without lubrication and high pV rate make it an ideal material for challenging friction and wear applications, prolonging service life and reducing maintenance costs.

Applications in vacuum, aerospace and semiconductor industries require high purity and low outgassing. To sum up, the advantages of polyimide include:

Non-melting high temperature polyimide

Long-term thermal stability at 300°C (up to 400°C in short term)

Heat resistance up to 470 c (HDT/year)

Good low temperature performance as low as-270 C.

It also has high strength, modulus and stiffness at high temperature above 260℃

Excellent thermal insulation and electrical insulation.

High purity, low degassing under vacuum condition

Good machinability

Inherent flame retardant
