Characteristic
PEI has unique strength and rigidity, as well as excellent high temperature resistance, flame retardancy, electrical performance, chemical resistance, and radiation resistance.
High temperature resistance: HDT exceeding 200 ℃, UL continuous application temperature exceeding 170 ℃.
Flame retardancy: Oxygen index greater than 4.7, low smoke emission and UL94V-0/5V.
Electrical performance: It has stable dielectric constant, dielectric loss, and extremely high dielectric strength over a wide frequency and temperature range.
Chemical resistance: including resistance to most hydrocarbons, alcohols, and all halogenated solvents, resistance to inorganic acids, and short-term resistance to weak bases.
Application Area
Widely used in high-temperature resistant terminals, IC bases, lighting equipment, FPCB (flexible circuit board), liquid delivery equipment, aircraft internal parts, medical equipment, and household appliances.
