Polymers with high melting temperatures
WebBut the presence of solid fillers results in a dramatic increase in the melt viscosity. Thermotropic liquid crystalline polymers(LCP) have been studied because of then-inherent high stiffness and strength, high use temperature, excellent chemical resistance, low melt viscosity, and low coefficient of expansion. WebApr 14, 2024 · The physical parameters of slag and copper matte under high temperature melting state were provided by the copper smeltery. Under the initial conditions of numerical simulation, the temperature of the melt phase was 1,573.15 K, and the temperature of the primary air inlet flow was 293.15 K.
