Omnia Plastica PEI Polyetherimide
Categories:	Polymer; Thermoplastic; Polyetherimide (PEI)
Material Notes:	This high performance engineering plastic is a non-reinforced self-extinguishing amorphous polymer with high thermal, electrical and mechanical properties which are typical of a crystalline polymer. Features: Resistance to high temperature Flame resistance: self-extinguishing, low oxygen index. Mechanical properties: high tensile stress, flexural strength, E.modulus Chemical resistance Electrical properties Weak Point: The cost is higher than conventional engineering plastics. The shock resistance is not high. Application: Electrical: very good insulating and dielectric properties. It is irreplaceable in many applications in this field thanks to its self-extinguishing property and low smoke emission. Mechanical: it is used for high performance components such as bearings, precision gears, etc. at low as well as high temperatures. The dimensional stability is excellent, as is the heat resistance. Chemical: good chemical and thermal properties. Food contact: physiologically inert Information provided by Omnia Plastica s.p.a. for semifinished products such as sheet, rod, and tube.
