Our experimentation that PET resin of 0 76[n] [n] value increase 0 01 pitch as moisture retained in the melted PET resin increases 16 ppm Drying PET resin is the reverse phenomenon of the moisture absorption process Absorbed moisture defuses to the center a pellet In order to get the reverse effect of this process a pellet which has absorbed moisture shall be exposed to extremely dry

Drying and Crystallization of PET to 150 ppm The challenge Processing of PET material with initial moistures of up to 13 000 ppm (PET bottle flakes) or 6 000 ppm (PET sheet flakes) for processing on single-screw extruders or twin-screw extruders with vacuum degassing The goal Achieve moisture content of 150 ppm Prevent sticking and clumping of the material in the extruder intake and

For instance with PET processing it is generally assumed that if there is 4-6 hours in the drying hopper at 325-350 F the moisture will be reduced to less than 50 ppm Husky machines rely on the heat from drying to process the material to achieve the cycle times
