The melting temperature of POM is 165 C, and the extrusion
granulation temperature can generally be set at 175 ~ 190 C. Under
the premise of ensuring full melting, the material temperature
should not be too high. Because POM is a shear-sensitive polymer,
when the melt temperature is above the melting point, the melt
fluidity is more sensitive to the shear rate, so the shear rate can
be set higher, which is conducive to the extrusion of materials.
But considering the effect of shear heat at high speed, the main
engine speed is usually set at 260-300 rpm. Granulation
temperature: When POM is extruded by twin screw extruder, the
phenomenon of holes in the center of particles often occurs. This
is because POM is a crystalline polymer, its melt is often
accompanied by larger volume changes when it is cooled. In the
extrusion process, when the melted strip enters the cooling tank,
the surface will instantly solidify into a surface cortex, while
the core part is still in a melting state. With the continuous
hardening of the strip from outside to inside, the shrinkage force
caused by volume reduction will act on the core part which is not
yet hard. The resin, which is equivalent to an equal tension on the
core, results in continuous shrinkage along the length of the core
of the strip
