In addition to these characteristics Duratron D7000 PI offers great chemical resistance high strength and toughness and outstanding dimensional stability. For these reasons Duratron D7000 PI is often seen as an ideal solution for insulators high temperature fixtures valve seats gaskets and seals. ISO ASTM Notes see datasheet
on page 1 1. The figures given for these properties are for the most part derived from raw material supplier data and other publications. 2. Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature PBI PI. 3. Temperature resistance over a period of min. 20000 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 of rods 40-60 mm when available else out of plate 10-20mm. All tests are done at room temperature 23 73F 7.

Irrespective of any
tests that Mitsubishi Chemical Advanced Materials may have carried out with respect to any Product Mitsubishi Chemical Advanced Materials does not possess expertise in evaluating the suitability of its materials or Products for use in specific applications or products manufactured or offered by the customer respectively. The choice of the most suitable plastics material depends on available chemical resistance data and practical experience but often preliminary testing of the finished plastics part under actual service conditions right chemical concentration temperature and contact time as well as other conditions is required to assess its final suitability for the given application. It thus remains the customers sole responsibility to test and assess the suitability and compatibility of Mitsubishi Chemical Advanced Materials Products for its intended applications processes and uses and to choose those Products which according to its assessment meet the requirements applicable to the specific use of the finished product. The customer undertakes all liability in respect of the application processing or use of the aforementioned information or product or any consequence thereof and shall verify its quality and other properties. 2 of 2
