IXEF就比POM强度要好啊!
高硬度:
拉伸模量: 23 GPa at 23 °C
高强度:
挠曲强度:400 MPa at 23 °C
very low creep
Deformation of less than 1 % after 1000 hours under 50 MPa at 50 °C, for certain grades. For the same glass fibre content, the creep resistance is superior to that of most engineering polymers.
Excellent surface finish
Superb surface appearance for a reinforced product even with a high glass fibre content.
Ease of processing
Good injectability, even with a high glass fibre content, allowing the manufacture of complex or thin-walled items.
Good dimensional stability
Low mould shrinkage, highly reproducible, allowing tight tolerances to be maintained (length tolerance, as little as ± 0.05 %, when the correct moulding conditions are used).
Slow rate of water absorption
Like all polyamides, polyarylamide has a certain sensitivity to water. Even so, the semi-aromatic character of polyarylamide induces a lower and slower water absorption in IXEF compounds than that found in items moulded in PA 6 and PA 66, which are more sensitive to humidity. |
