Suitable for convey/pressurizing/metering high temperature, high viscosity polymer melt and synthetic fibers. Mainly used in extrusion of polymer , such as compounding, film , pipe, plate, sheet , non-woven fabrics industry, and is usually installed between the die  and head of the extruder, can also be installed through connection pipe  used for the transfer  of the high viscosity  polymer.

Suitable materials:

PA, PB , PC , PE , PS, HIPS, , the ABS , PP , PET, PVA and other polymers, can also be used to transport rubber, asphalt, paint , adhesives , dyes , paints , lubricants , polyols and other non- particulate impurities in high- viscosity materials.
