Immersion or spray rinsing can be followed by an optional hot air predry
for three days in a shallow, mesh-bottomed tray through a combination of sun and passive air movement.
This product line extension will enable manufacturers of tubing, insulated wire and extruded profiles to enjoy the benefit of almost instant heat-up and cool-down that manufacturers who dry and predry
technical textiles and coated webs enjoy with Glenro's infrared heaters and ovens.
We were putting materials in to dry way ahead of time, and on bigger jobs we needed two drying systems to do that: One dryer to predry
material and then, of course, a production dryer to keep it dry and running.
A laboratory twin-screw extruder, Brabender Model D6/2 was used for blending the predry
Polyolefin processors molding and extruding products for automotive, medical, and certain other markets sometimes predry
materials to remove surface moisture and, in effect, "preheat" or soften the material to facilitate melting.
The new masterbatches are based on Ampacet's Formula X PET technology platform, which eliminates the need to predry
PET colors and allows for feeding at the extruder throat--thus reducing feed-throat clogging and screw slippage, and improving color dispersion.
gives processors another option to extrude PET and PLA sheet without needing to predry
or crystallize the material.
Molders must predry
grades containing conductive fillers that draw moisture into the polymer.
