- the polyester molding composition according to the invention may be the substrate itself or the substrate carrier or Hybrid / Bi injection parts a defined substrate area, which also by subsequent chemical (eg etching) or physical treatment (eg or LASER removal) can be brought to the surface.
- etching chemical or physical treatment
- LASER removal physical treatment
- Component A Ultradur® B2550 from BASF SE (PBT with a viscosity number according to DI N 53728 of 1 10 cm 3 / g)
- Component B aluminum hypophosphite (ex. Italmatch Chemicals)
- Component C melamine cyanurate having a mean particle size dso of -2.6 ⁇ m (Melapur®MC
- Component D / 2 short glass fiber PPG 3786 (PPG) with a diameter of 10 ⁇ m and an average fiber length of 4.5 mm.
- Component E / 1 Luwax®OA5 (BASF SE) Polyolefin wax
- the molding compositions were prepared as follows:
- the individual components A - C and E) were mixed in a side-mounted twin-screw extruder at 240 ° C and filled with a mass flow of 26 kg / h via a transition in the 255 ° C hot impregnation chamber.
- Rovings were preloaded so that the individual glass fibers did not touch each other and pulled through the polymer melt at a constant speed of 6 to 10 m / min and thereby completely impregnated with the polymer melt and then cooled to about room temperature and cut into about 12 mm long rods ,
- the long fiber reinforced rod granules obtained in this way had an L / D ratio of about 700.
- the specimens for the tests listed in Table 1 were sprayed on an Arburg 420C injection molding machine at a melt temperature of about 260 ° 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 flame retardancy of the molding compositions was determined, on the one hand, by the method UL94V (Underwriters 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 was determined in accordance with GWIT (Glow Wire Ignition Temperature) according to DIN EN 60695-2-13 and the GWFI (Glow Wire Flammability Index) according to DIN EN 60695-2-12.
- GWIT Low Wire Ignition Temperature
- GWFI Low Wire Flammability Index
- the maximum temperature is determined on 3 specimens (for example on 60 x 60 x 1.5 mm plates) with the aid of a glowing wire at temperatures between 550 and 960 ° C, and in 3 consecutive tests during the exposure time of the filament does not lead to ignition.
- the specified glow wire ignition temperature is 25K above the maximum determined temperature.
- the criterion of ignition is a flame with firing times> 5 sec. Compositions of the molding compositions and the results of the measurements are shown in the table.
