Product Advantages
High Strength: Tensile strength is increased to 150-200 MPa (100-130 MPa for pure PEI), and flexural modulus reaches 5-7 GPa
High Heat Resistance: Heat Deformation Temperature (HDT) is increased to 220°C (1.82MPa burden), short-term resistance to 260°C.
Dimensional Stability: Low shrinkage (<0.1%), suitable for precision parts.
Chemical Resistance: Resistant to strong acids, strong alkalis, esters, ketones and aromatic hydrocarbons.
Lightweight: Density 1.35-1.45 g/cm3, more than 50% lighter than metal.
Environmental Compliance: Halogen-free, UL94 V-0 flame retardant, and FDA medical certification.
Why choose PEI GF?
Harsh environment adaptation: automotive turbochargers and engine peripheral parts need to be resistant to high temperatures and chemical corrosion.
Lightweight structure: Replace metal parts, reduce weight, and improve fuel efficiency (automobile/aviation).
Long-term reliability: Creep resistance, fatigue resistance, suitable for long-term load parts (such as connectors, sensors).
Processing efficiency: The fluidity is better than metal, supporting complex structure injection molding.
Typical applications
Automotive sensors: High temperature environment around the engine (resistant to 150°C oil vapor).
Lithium battery components: Battery module seals (resistant to electrolyte penetration + insulation).
Aviation fuel system: Fuel pump seals (resistant to aviation kerosene + resistant to high temperature aging).
