PVC Twin Screw Extruder

PVC Twin Screw Extruder

PVC is a non-crystalline polymer of polyvinyl chloride. Its glass transition temperature is 105℃-75℃ depending on the molecular weight. It has flame retardancy, high rigidity, excellent chemical resistance, and electrical insulation, but it is a heat-sensitive resin.

Its processing temperature is higher than the decomposition temperature, so it cannot be processed without modification. Modified PVC is the plastic with the most additives. According to needs, PVC can be modified to produce soft, hard, transparent and opaque products by PVC twin screw extruder machine.

PVC Twin Screw Extruder Application

PVC plastic pipe, PVC plastic tape, PVC toys, PVC wire, PVC plug, PVC injection molding, container PVC accessories, food, medicine packaging, color chaotic PVC plastic bottles, supermarkets have a dazzling array of PVC packaging bags.

It is suitable for the production of profile, PVC pipe, PVC profile, wire, and cable insulation, PVC plugs, and has a low sealing softening point. Pieces, toy figures, profiled materials, etc.

PVC Twin Screw Extruder Performance and Advantages

Flexible operation. The conical twin screw extruder PVC is a twin screw compounding machine running at high speed, with forced conveying, high efficiency plasticizing mixing and shearing dispersion, and no head back pressure reflux, avoiding high shear overheating. The lower step extruder is a large diameter single screw extruder running at low speed, with separate temperature control and low.

Speed running shear force is small, screw internal cooling to avoid the decomposition of plasticized materials, single screw extrusion to ensure the establishment of pressure, stable extrusion. Application: thermal sensitive polymer processing, large capacity exhaust devolatility processing.
