Natural color Light ivory, opaque Colors In addition to uncolored and black material, a series of opaque standard colors is available. Special colors are also possible Surface finish High-gloss, good mold surface reproduction Stiffness High to very high; tensile modulus = 1,700 to 17,000 MPa Impact and break resistance High, but notch-sensitive; elastomer-modified grades have good low-temperature impact strength Resistance to dynamic loading High Stress crack resistance Good Heat resistance High; short-term peaks from 160 to 210 °C (up to approx. 240 °C with selected glass fiber reinforced grades); Permanent service temperature 90 to 140 °C Dimensional accuracy and stability Good, but not quite on the same level as amorphous thermoplastics Abrasion resistance Good Chemical resistance Good; particularly resistant to fuels, lubricants, solvents and cleaning fluids Electrical insulation Good: dielectric strength = 20 to 35 kV/mm; Volume resistivity = 1014 to 1016 Ohm • cm; Comparative Tracking Index: 175 to 600 Processability Easy flow, rapid solidification (fast cycles) Other properties Low moisture absorption, low surface friction
