1 PA 2200 PA 2200 is a non-filled powder on basis of PA 12. General Properties Property Units Water absorption ISO 62 / DIN C, saturation in water % C, 96% RF % C, 50% RF % 0.52 Property Unit Coefficient of linear thermal expansion ISO / DIN A x10-4 /K 1.09 Specific heat DIN J/gK 2.35 Thermal properties of sintered parts Property Unit Thermal conductivity DIN vertical to sintered layers W/mK parallel to sintered layers W/mK Robert-Stirling-Ring 1 D Krailling / München Telefon: +49 (0)89 / AHO / Telefax: +49 (0)89 / PA2200_Product_information_03-10_en.doc 1 / 10 Internet:
2 Short term influcence of temperature on mechanical properties An overview about the temperature dependence of mechanical properties of PA 12 can be retrieved from the curves for dynamic shear modulus and loss factor as function of temperature according to ISO E+10 PA 2200 dynamic mechanical analysis (torsion) Temp.: bis 188 C G' G" tan_delta 1E+03 1E+09 1E+02 storage modulus G [Pa], loss modulus G [Pa] 1E+08 1E+07 1E+01 1E+00 1E-01 tan_delta 1E+06 1E-02 1E+05 1E Temperature [ C] In general parts made of PA 12 show high mechanical strength and elasticity under steady stress in a temperature range from - 40 C till + 80 C. Short time loading of parts made of PA 12 without stress is possible up to 160 C. Long term properties under mechanical load and temperature In general thermoplastics have higher mechanical strength under short term load then under long term load (> 1000 h) as result of creep. This occurs mostly at higher temperatures and leads to a reduction of modulus (creep modulus). Usually the creep resistance (mechanical properties under continuous load) is determined with the uniaxial tensile creep test (DIN 53444) under different loads and temperatures.
