Product Description

Introduction of Polyimide Foam Core

 

 

 

 

  Polyimide (Polyimide, PI) refers to the molecular structure of the aryl heterocyclic polymer compounds containing imide groups, the main chain of the aryl ring and heterocyclic as the main structural unit, the beginning of the research is to meet the aerospace field for heat-resistant, high-strength, lightweight structural materials for the urgent needs of the polymer materials, polyimide is the best polymer materials can be used in practice the best overall performance, is located in the polymer new material Polyimide has excellent performance.

  Polyimide has excellent performance, its high temperature resistance, low temperature resistance, strong insulation, coefficient of thermal expansion similar to that of metals, excellent mechanical properties and processing performance, non-toxic, intrinsic flame retardant and other characteristics, so that it is widely used in various fields and play an irreplaceable role.
