PEEK Tube Extrusion Material (Victrex PEEK 381G)

Extrusion Process of Victrex PEEK381G

When using Victrex PEEK381G for extrusion molding, the following process points need to be noted:

Drying Treatment: Since polyetheretherketone resin is sensitive to moisture, thorough drying is required before processing to prevent hydrolysis and performance degradation of the product. Typically, it can be dried in an oven at around 70°C for 4-6 hours or longer until the moisture content is reduced to below 0.05%.
Processing Temperature: Processing temperature is one of the critical factors affecting the extrusion molding of Victrex PEEK381G. Strict control of the processing temperature is necessary to ensure proper melting and plasticization of the material. Generally, the processing temperature for a screw extruder can be set between 390-420°C. Extrusion Process of Victrex PEEK381G
