Abstract:
Temperature scanning tests and uniaxial tensile tests at room temperature under different strain rates for three kinds of existing low-temperature outside fixed thermoplastic medical polymer resin materials (A, B and C) were conducted on dynamic mechanical analyzer and micro material testing machine to contrast their mechanical properties. It is shown that the glass transition temperatures of these three materials are all around 65 degrees C, but material C has the widest range of shaping temperature. Stress-strain responses of the three materials are rate-dependent and material C shows better plasticity.
