What plastic materials is the BOPP extrusion melt pump suitab
The melt pump for BOPP film extrusion is primarily suited for the conveyance, pressurization, and metering of high-temperature, high-viscosity polymer melts. These polymer melts are commonly used in the manufacture of plastic products, including but not limited to the following plastic materials:
Polypropylene (PP): Especially biaxially oriented polypropylene (BOPP), which is the primary application target of the melt pump in the film extrusion process. BOPP materials exhibit excellent transparency, gloss, barrier properties, and mechanical strength, making them widely used in packaging, printing, labeling, and other fields.
Polyethylene (PE): PE materials possess good flexibility, impact resistance, and chemical stability, and are also commonly used with melt pumps in the extrusion process. PE films are widely applied in food packaging, agricultural mulching, industrial packaging, and other areas.
Other polymer materials: In addition to PP and PE, melt pumps can also be used with other types of polymer materials, such as polyvinyl chloride (PVC), polystyrene (PS), polyethylene terephthalate (PET), and more. These materials require stable melt pressure and flow rate during the extrusion molding process to ensure product quality and output.
It should be noted that the specific applicable scope of a melt pump also depends on its design and configuration. Different models of melt pumps may have different working pressures, flow ranges, and temperature ranges. Therefore, when selecting a melt pump, it is necessary to match it according to the specific extrusion process and material characteristics.
Furthermore, the application of melt pumps in the plastic extrusion industry is not limited to film extrusion; they can also be used in the extrusion molding processes of granulation, tubing, sheeting, and plank production to improve production efficiency and product quality.
