PI (Polyimide)
PI polymer has a wide range of applications, e.g., aerospace, automotive, electric and electronic fields, and so on, because of its great mechanical, thermal, electrical, and chemical properties.
PBI Advanced Materials selects the Evonik Fibres’ polyimide: P84NT1 and manufactures the stock shapes. Compared with competitor’s PI, our PI shows higher mechanical properties that makes it possible to design flexibly.
