Short term influence 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 a function of temperature according to ISO 537.
Temperature analysis shows:
- Parts made of PA 12 show high mechanical strength and elasticity under steady stress in a temperature range from -40°C to +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 than under long term loads (> 1000 h) as a result of creep. This occurs mostly at higher temperatures and leads to a reduction of modulus (creep modulus). The creep resistance is determined with the uniaxial tensile creep test (DIN 53444) under different loads and temperatures.
