Features:
| Inherent colour |
opaque, non-transparent |
| Colour range |
natural-coloured, black and selected colours; cadmium
and lead pigments are not employed as a matter of principle |
| Surface finish |
glossy; accurate reproduction of detail, matt effect
attainable with a grained surface |
| Stiffness |
tensile modulus = 1300 to 1900 MPa |
| Impact and fracture resistance |
very good; low temperature resistance to -40 °C |
| Chemical resistance |
resistant to a large number of chemicals and particularly
to fuels, lubricants, solvents and cleaning agents |
| Resistance to stress cracking |
good |
| Heat resistance |
service temperature for moulded parts is between that
of ABS and polyamide (depending on the grade), VST/B 120: 105 °C,
VST/A 120: 190 °C |
| Dimensional accuracy and stability |
good; low anisotropy and hence a low tendency to warp |
| Electrical insulation |
good; dielectric strength: 24 to 36 kV/mm; volume resistivity:
1012 to 10 15 Ohm • cm; tracking, CTI: rating > 600 |
| Further properties |
good acoustic damping properties, good abrasion resistance |
| Processability |
good flowability, reduced anisotropy compared with polyamide |
|
