All rights reserved. - Date of issue revision 05072023 Electrical Properties Mechanical Properties 6 Thermal properties 1 Melting temperature DSC 10C 50F min Miscellaneous PRODUCT DATASHEET Ertalyte PET is an unreinforced semi-crystalline grade produced from our proprietary resins and characterized by its excellent wear resistance low coefficient of friction high strength and resistance to moderately acidic solutions. This grade is capable of sustaining high loads and retains more of its original strength up to 180 F 85 C than nylons or acetals. Due to these characteristics Ertalyte PET components are a favored solution for bearing and structural applications throughout the pharmaceutical food processing and packaging and oil and gas industries. ISO ASTM Notes see datasheet on page 1 1. The figures given for these properties are fo
r 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.
