Instructions

If the inner bag fails to prevent moisture or has a long storage time, the material should be dried before feeding and extruding. It is better for the hot material to enter the extruder. It is better to use a low shrinkage ratio (1.25-2.0:1) for the screw. Please contact the supplier first if you use an equidistant and unequal depth single-thread screw or other screw extrusion. Recommended process conditions (for reference only)
