What material is suitable for small twin-screw granulator?

Materials suitable for small twin-screw granulator: such as glass fiber reinforced and flame retardant (such as PA6, PA66, PET, PBT, PP, PC reinforced flame retardant, etc. ); High filler (such as PE and PP filled with 75%CaCO). ); Heat-sensitive materials (such as PVC and XLPE cable materials); Concentrated masterbatch (for example, filled with 50% toner); Anti-static master batch, alloy, coloring and low filling * * * mixed granulation; Cable materials (such as sheath materials and insulation materials); XLPE pipes (such as masterbatch for hot water crosslinking); Thermosetting plastics (such as phenolic resin, epoxy resin, powder coating); Hot melt adhesive, PU reactive extrusion (such as EVA hot melt adhesive, polyurethane), K resin, SBS devolatilization granulation, etc.

Twin screw granulator

Function of small twin-screw granulator: (1)*** mixed modification? Extruding and mixing different kinds and brands of plastics to make homogeneous plastic alloy or mixture to obtain polymer materials with specific properties;

(2) Filling Modification Various inorganic fillers, such as calcium carbonate and talcum powder, are added to the plastic matrix, which greatly reduces the cost of the product and improves the physical and mechanical properties of the material;

(3) Functionalization of composite materials Various additives, such as stabilizers, flame retardants, colorants, etc. Mixing in plastics to obtain new materials with uniform dispersion and specific functions;

(4) Reinforcement modification: Reinforcing components, such as glass fiber, carbon fiber and other fillers, are added to the plastic matrix to improve the physical and mechanical properties of the composite material;

(5) Extrusion granulation The equipment can realize uniform granulation of polymers and their composites;

(6) Exhaust and devolatilization? That is, in the process of plasticizing and mixing, various volatile components such as monomer, solvent, moisture and oligomer remaining in the polymer can be quickly eliminated, and the product performance can be improved;

(7) Screw recombination By optimizing the screw combination, the instrument can be used in special fields such as mixed granulation of various powder materials and thermosetting plastics, reactive extrusion of polymers, etc.
