The Effect of Thermal Transformations on the Melt Mass-flow Rate and the Melt Volume-flow Rate of Abs
(Aeternitas Publishing House, 2013) Mazur, Piotr; Chełstowski, Karol
The melt mass-flow rate and the melt volume-flow rate determine the processing conditions for thermosetting plastics, and in recycled materials, they are indicators of the susceptibility of polymers to recycling and its frequency. This paper investigates the melt mass-flow rate and the volume-flow rate of ABS subject to the number of thermal transformations, including transitions to plastic state, liquid state and solid state induced by cooling. The results were subjected to mathematical analysis. The examined melt flow rates change very slowly, therefore, polymer materials can be processed repeatedly.
