What materials are suitable for FDY melt pumps?

The materials suitable for FDY melt pumps primarily reside in the field of polymers, particularly those requiring the conveyance, pressurization, and metering of high-temperature, high-viscosity melts. Below are some common materials that FDY melt pumps are well-suited for:

Primary Applicable Materials:

1. Polyester (PET):

Polyester fibers are among the most frequent applications for FDY melt pumps. In the spinning process of polyester fibers, the FDY melt pump is responsible for stably conveying the high-temperature molten polyester to the spinning components, ensuring the stability of the spinning process and product quality.

2. Other Polyester Materials:

Besides PET, other polyester materials such as Polybutylene Terephthalate (PBT) and Polybutylene Terephthalate Benzene Bisol (PBTB) may also utilize FDY melt pumps for their conveyance and processing.

3. Nylon (Nylon):

Nylon, an essential engineering plastic, may also necessitate the support of FDY melt pumps during its spinning and processing procedures. The high viscosity and sensitivity to temperature and pressure of nylon melts make FDY melt pumps a crucial equipment in its processing.

4. Polypropylene (PP):

Although polypropylene has a relatively low melting point, FDY melt pumps may still be utilized in certain specific spinning or processing processes to ensure stable melt conveyance and precise metering.

5. Other Polymer Materials:

Apart from the above-mentioned materials, FDY melt pumps are also suitable for processing various other polymer materials such as Polyvinyl Chloride (PVC), Polystyrene (PS), and Polyurethane (PU). These materials, in their molten state, exhibit high viscosity and fluidity requirements, necessitating stable conveyance and pressurization support from FDY melt pumps.

Precautions:

Material Properties: When selecting an FDY melt pump, factors such as the viscosity, temperature sensitivity, and corrosiveness of the processed material must be considered. Different materials may have varying requirements for pump performance and material compatibility.

Process Requirements: Different production processes impose distinct requirements on the performance indicators of melt pumps. For instance, spinning processes demand high uniformity and stability of the melt, while injection molding or extrusion processes may prioritize melt pressure and flow rate control.

Equipment Compatibility: FDY melt pumps typically work in conjunction with upstream equipment like extruders and spinning machines. Hence, compatibility and matching with these upstream devices should be taken into account during pump selection.

In conclusion, FDY melt pumps are suitable for processing a diverse range of polymer materials. However, specific choices must be made based on comprehensive considerations of material properties, process requirements, and equipment compatibility.
