Plastic & Polymer Sorbents

Sorbents for Plastics & Polymer Processing

Enhance plastic and polymer manufacturing with sorbents that improve stability, flow, and filtration. Our products support extrusion, injection molding, and compounding - helping manage moisture, remove trace impurities, and act as carriers for additives. Ideal for thermoplastics, resins, and specialty polymers.

Applications & Functional Benefits

Moisture control: Silica gel, molecular sieve, and alumina reduce hydrolysis and splay in hygroscopic resins.
Flow & dispersion: Silica/clay carriers aid uniform distribution of pigments, stabilizers, and performance additives.
Filtration & clarity: Mineral sorbents capture fines, gels, and polar contaminants to protect screen packs and improve finish.
Odor/VOC reduction: Activated media and mineral blends help adsorb residual monomers and processing odors.

Why Choose Sorbents Direct

Targeted grades: Powder, granular, and pellet formats to suit dosing systems and compounding lines.
Process alignment: Mesh/particle-size options to tune melt flow, filtration efficiency, and dispersion.
Documentation & quality: SDS/TDS/COA available with lot traceability for QA programs.
Scalable supply: From lab trials and masterbatch runs to bulk packaging and nationwide freight.

Example Application

A film extruder introduced a silica-based carrier in a masterbatch to improve additive dispersion and added a moisture scavenger for a hygroscopic copolymer. The line saw fewer screen changes, reduced haze, and more consistent gauge without altering screw design.
