Product Details

ISO 11443:2005 specifies methods for determining the fluidity of plastics melts subjected to shear stresses at rates and temperatures similar to those arising in plastics processing. Testing plastics melts in accordance with these methods is necessary since the fluidity of plastics melts is generally not dependent only on temperature, but also on other parameters, in particular shear rate, shear stress, molecular weight, filler content. The shear rates occurring in extrusion capillary rheometers range from 1 s-1 to 10s-1, and the capillary rheometers are able to cover the full range of processing conditions including extrusion and injection moulding.
