- test specimens for the test listed in Table 1 were sprayed on an Arburg 420C injection molding machine at a melt temperature of about 270 ° C. and a mold temperature of about 80 ° C.
- test specimens for the tension tests were produced according to ISO 527-2: / 1993 and the test specimens for the impact measurements according to ISO 179-2 / 1 eA.
- the MVR measurements were carried out according to ISO 1 133.
- the flame retardance of the molding compositions was determined, on the one hand, by the method UL94-V (Underwrite's Laboratories Inc. Standard of Safety, "Test for Flammability of Plastic Materials for Parts in Devices and Appliances", p. 14 to p. 18 Northbrook 1998) ,
- the glow-wire resistance GWFI (Glow Wire Flammability Index) on boards was carried out in accordance with DIN EN 60695-2-12.
- the GWFI is a general suitability test for plastics in contact with live parts. The highest temperature is determined in which one of the following conditions is met in 3 consecutive tests: (a) no ignition of the sample or (b) afterburn time or afterglow time ⁇ 30 s after the end of the glow wire exposure time and no ignition of the substrate.
