PEI GF SHEET AND ROD

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.

(polyetherimide) PEI glass fiber rod high temperature resistance

 

 

PEI GF extruded is an amorphous polymer offering high strength and excellent flame and heat resistance. It performs continuously to 340°F (170°C), making it ideal for high strength/ high heat applications, and those requiring consistent dielectric properties over a wide frequency range. It is hydrolysis resistant, highly resistant to acidic solutions and capable of withstanding repeated autoclaving cycles. PEI glass-reinforced versions which provide even greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of basic PEI.

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).
