Unfilled Pure Standard Flow PEI 1000 Pellets for Injection
1. High temperature resistance:
The glass transition temperature (Tg) of PEI is 215-217 ° C, with a long-term use temperature of 170-180 ° C and a short-term over 200 ° C
2. high Strength and modulus:
The tensile strength is approximately 105-150 MPa (unreinforced), and the bending modulus is 3.3 GPa
3.Resilience:
fracture elongation of 60-80%, with excellent ductility
Creep resistance and fatigue resistance: Outstanding creep resistance and excellent fatigue resistance under long-term load, suitable for cyclic load components
4. Chemical and hydrolysis resistance
Chemical resistance: resistant to most hydrocarbons, alcohols, inorganic acids, and halogenated solvents, but soluble in strong bases and some halogenated hydrocarbons (such as chloroform)
Hydrolysis resistance: After soaking in boiling water for 10000 hours, the tensile strength remains above 85%, and the performance hardly deteriorates after 2000 cycles of steam hot pressing
5. Electrical performance
Dielectric properties: The dielectric constant and dielectric loss remain stable over a wide temperature range (-40 ° C to 150 ° C) and high frequencies, with a dielectric strength of 33-35 kV/mm and a volume resistivity greater than 1 × 10 ΩΩ· cm
