Polymers & resins separation
Account for particle stickiness, temperature-dependent viscosity, fines and discharge behaviour. A process sample should represent the actual material reaching the separation machine.

The engineering conversation
When viscosity increases, drainage or settling can become slower under otherwise comparable conditions. However, heating is not a universal solution: crystals may dissolve, the product may degrade, seals may be affected or solvent hazards may change. Cooling can also create crystallization inside transfer lines or alter cake structure. The tested condition should represent the expected machine inlet, not merely the storage tank.
Include temperature control, insulation or heat-exchange interfaces in the scope where they matter. Ask for performance data at the agreed process condition. Do not extrapolate a catalogue capacity across a large viscosity change without a validated basis.
