Desiccant Masterbatches
A simple and economical way to eliminate moisture problems in polymer processing.
Simple and economical moisture elimination.
Desiccants (moisture scavengers), are materials that will attract and chemically bind moisture and can offer a simple and economical way to eliminate moisture problems in plastics processing that can otherwise cause unattractive surface defects such as lensing, voiding, and splash marks in the finished product.
Desiccant masterbatches can reduce the need for pre-drying of materials, allowing processors to use recyclate with high moisture content and extend the processing window for moisture sensitive polymers.
How it works.
Wells desiccant masterbatches contain highly concentrated levels of a high purity, controlled particle size active ingredient. This will absorb and chemically lock in any moisture present in the system and prevent it from being released as steam during processing.
Typically, 1wt% addition of a desiccant masterbatch will absorb in excess of 3000ppm moisture.
Wells desiccant masterbatches have proven to be highly effective in reducing fish eyes and voiding in recycled films such as bin bags and eliminating surface defects in high gloss ABS sheets containing recycled material.
Due to the carefully controlled particle size of the active ingredient, Wells desiccant masterbatches are suitable for use in thin films.
Applications: Blown film, Sheet extrusion, Profile Extrusion, Blow Moulding, Injection Moulding
Polymer Carriers Available: PE
