- Note
- 1 The figures given for these properties are for the most part derived from raw material supplier data and other publications.
- 2Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature (PBI & PI).
- 3Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength - measured at 23 °C - of about 50 % as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes place and causes a reduction in properties. Note, however, that the maximum allowable service temperature depends in many cases essentially on the duration and the magnitude of the mechanical stresses to which the material is subjected.
- 4 Impact strength decreasing with decreasing temperature, the minimum allowable service temperature is practically mainly determined by the extent to which the material is subjected to impact. The value given here is based on unfavourable impact conditions and may consequently not be considered as being the absolute practical limit.
- 5 These estimated ratings, derived from raw material supplier data and other publications, are not intended to reflect hazards presented by the material under actual fire conditions. There is no ‘UL File Number’ available for these stock shapes.
- 6 Most of the figures given for the mechanical properties are average values of tests run on dry test specimens machined out rods 40-60 mm when available, else out of plate 10-20mm. All tests are done at room temperature (23° / 73°F)
- 7 Test speed: either 5 mm/min or 50 mm/min [chosen acc. to ISO 10350-1 as a function of the ductile behaviour of the material (tough or brittle)] using type 1B tensile bars
- 9 Test speed: 1 mm/min, using type 1B tensile bars
- 10 Test specimens: cylinders Ø 8 mm x 16 mm, test speed 1 mm/min
- 11 Test specimens: cylinders Ø 0.5" x 1", or square 0.5" x 1", test speed 0.05"/min
- 12 Test specimens: bars 4 mm (thickness) x 10 mm x 80 mm ; test speed: 2 mm/min ; span: 64 mm.
- 14 Measured on 10 mm, 0.4" thick test specimens.
- 15 Electrode configuration: Æ 25 / Æ 75 mm coaxial cylinders ; in transformer oil according to IEC 60296 ; 1 mm thick test specimens.
- 16 Measured on discs Ø 50 mm x 3 mm.
- 17 Measured on 1/8" thick x 2" diameter or square
- 18 Test procedure similar to Test Method A: “Pin-on-disk” as described in ISO 7148-2, Load 3MPa, sliding velocity= 0,33 m/s, mating plate steel Ra= 0.7-0.9 μm, tested at 23°C, 50%RH.

Technical Details & Test Data
- Material Selection
Handling (Machining) :
- During machining of the semi-finished products, evacuate swarf to prevent slipping or tripping hazard and observe the maximum allowable concentration of dust and
- formaldehyde levels on the workplace which apply in your country.
- Wear safety goggles during machining.
Storage:
- The products shall be stored indoors in a normal environment (air at 10 - 30°C / 30 - 70% RH) and kept away from any source of degradation such as sunlight, UV-lamps, chemicals (direct or indirect contact), ionizing radiation, flames, etc.
- Dimensional changes (camber, warpage, shrinkage …) of the products as well as slight color shifts of the external surfaces can occur with time.
- The latter does generally not pose a problem in case of semi-finished products since the surface-layer is mostly removed anyway upon machining them into finished parts.
Safety measures:
- Standard industrial safety recommendations shall be observed.
- Temperatures above the melting temperature shall be avoided.
