Product Description

Polytek co-rotating twin-screw extruders are designed for maximum reliability, ease-of-use and flexibility. We offer turn-key solution for all types of material compounding applications.
we are proud to introduce our PTH series extruder which equiped with high torque and high speed gear box, desinged with specific torque of12Nm/cm3 to achieve high screw filling rate, which results in a decrease of melt temperature, thus improving compound quality.

what is twin screw extruder Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, one screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from one screw turns to the other screw and advances in a "∞" shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .
Polytek also have two stage extruder for PVC compound and high filler masterbatch extrusion.

Construction :

The Applications of Co-rotating Twin Screw Extruder
1.Glass fiber reinforced, fuel barrier palletizing (For example PA6, PA66, PET, PBT, PP, and PC reinforced flame retardant)2.Highly filled material granulation (For example PE, PP filled with 75%CaCo)3.Granulation of heat-sensitive materials (For example PVC, XLPE cable material)4.Intense color masterbatch (For example filled with 50% color powder)5.Antistatic masterbatches, alloys, coloring, low-fill co-mingling granulation6.Cable material granulation (For example sheathing material and insulation material)7.XLPE pipe material granulation (For example masterbatches for hot water crosslinking)8.Thermoset plastic compounding and extrusion (For example phenolic resin, epoxy resin, and powder coating)9.Hot melt adhesive, PU reactive extrusion palletizing (For example EVA hot melt adhesive and polyurethane)10.K resin, SBS de-volatile granulation
