What is Special Engineering Plastic?

Special engineering plastics are a type of high-performance polymer with characteristics such as high strength, high temperature resistance, corrosion resistance, electrical insulation, and lightweight. Common types include:
PEEK: High temperature resistance (250 ° C), used in aerospace and medical applications.
PI: High temperature resistance (above 300 ° C), used for high-temperature insulation.
PPS: Chemical corrosion resistance, used in automobiles and electronics.
PEI: Flame retardant and low smoke, used for aircraft interior and electronics.
PTFE: Corrosion resistant, low friction, used for sealing and coating.

Widespread Use of Special Plastics in the Aerospace Industry

1. PEEK (polyetheretherketone)
Performance advantages:
High temperature resistance: Long term use can reach a temperature of 250 ° C, and short-term tolerance can exceed 300 ° C.
High strength: The tensile strength can reach 90-100 MPa, close to certain metals.
Chemical corrosion resistance: has excellent resistance to fuel, hydraulic oil, solvents, etc.
Wear resistance: low friction coefficient, suitable for manufacturing bearings and seals.
Lightweight: The density is only 1.3 g/cm ³, much lower than that of metals.
Engine components: seals, bearings, gaskets, etc., need to work stably under high temperature and high pressure.
Structural components: brackets, connectors, etc., replacing metal to reduce weight.
Cable insulation: high temperature resistant, flame-retardant, used in aircraft electrical systems.
2. PI (Polyimide)
Performance advantages:
High temperature resistance: Long term use can reach temperatures above 300 ° C, and short-term tolerance can reach 500 ° C.
High mechanical strength: tensile strength exceeding 100 MPa, high rigidity.
Low thermal expansion coefficient: Excellent dimensional stability at high temperatures.
Electrical Insulation: Excellent insulation performance, suitable for electronic and electrical applications.
High temperature insulation material: used for insulation layer and cable insulation around the engine.
Bearings and seals: operate stably under high temperature and high load conditions.
Structural components, such as brackets, bushings, etc., replace metal to reduce weight.
3. PPS (Polyphenylene Sulfide)
Performance advantages:
High temperature resistance: The long-term use temperature can reach 200 ° C, and the short-term can withstand 240 ° C.
Chemical corrosion resistance: has excellent resistance to acids, alkalis, solvents, etc.
Flame retardancy: UL94 V-0 level flame retardant, suitable for aviation safety requirements.
Dimensional stability: Low moisture absorption, stable performance in humid environments.
Sensor housing: high temperature resistant, corrosion-resistant, used for engine monitoring systems.
Electrical connectors: flame retardant, insulated, used for aircraft electrical systems.
Pipelines and valves: resistant to chemical corrosion, used in fuel and hydraulic systems.

4. PEI (polyetherimide)
Performance advantages:
High temperature resistance: Long term use temperature can reach 170 ° C, short-term can withstand 200 ° C.
Flame retardancy: UL94 V-0 level flame retardant, low smoke and non-toxic, in compliance with aviation safety standards.
High rigidity: After glass fiber reinforcement, the mechanical properties are significantly improved.
Easy to process: can be formed through injection molding, extrusion and other processes.
Interior parts: seat brackets, panels, ventilation ducts, etc., must meet flame retardant and low smoke requirements.
Electronic equipment casing: high temperature resistant, insulated, used for protecting aircraft electronic equipment.
Pipelines and connectors: resistant to chemical corrosion, used in air and liquid transport systems.
5. PTFE (polytetrafluoroethylene)
Performance advantages:
High temperature resistance: Long term use temperature can reach 260 ° C, short-term can withstand 300 ° C.
Low friction coefficient: self-lubricating, suitable for manufacturing bearings and seals.
Chemical corrosion resistance: almost unaffected by all chemicals.
Electrical Insulation: Excellent insulation performance, suitable for electrical applications.
Aerospace applications:
Seals: such as O-rings and gaskets, used for fuel and hydraulic systems.
Bearings and guides: low friction, wear-resistant, used for moving parts.
Coating: Used on aircraft surfaces to reduce friction and corrosion.
