The most commonly GLS recommended color concentrates are based on polypropylene (PP) and thermoplastic polyurethane (TPU). Use low melt flow PP or HDPE.

The most commonly GLS recommended color concentrates are based on polypropylene (PP) and thermoplastic polyurethane (TPU). Use low melt flow PP or HDPE.

Common examples are polypropylene (PP), nylon (PA), polyketone (PK), and thermoplastic elastomers (TPE). Examples of semi-crystalline polymers are PP, polyethylene (PE), PA6, PA66, polyphthalamide (PPA), polybutylene/polyethylene terephthalate (PBT/PET), polyoxymethylene (POM) or acetal, polyphenylene sulfide (PPS), and polyether ether ketone (PEEK).

The colorant solutions are available in PP and PE (HDPE and LDPE) and produced with ingredients tested to European Pharmacopeia 3.1.3 and 3.1.5 as well as to USP chapters , including class VI (a requirement for ophthalmic and nasal drugs) and USP and (light transmission).

Suitable for use in polyethylene (PET) and polypropylene (PP) as well as in rPET and rPP applications

Available as a granular masterbatch for injection molding, thermoforming or extrusion, these new additives offer superior performance for most clear polymers, including polyethylene (PE), polypropylene (PP), polycarbonate (PC), polyethylene terephthalate (PET) and polystyrene (PS).

Additives for meltblown nonwoven PP

In addition, testing is underway to support an application for MPG recognition for the same colorants for polypropylene resin (PP).

Standard formulations in polycarbonate (PC), polyphenylene sulfide (PPS), and liquid crystal polymers (LCP) can be tailored to specific needs.

Together they developed a specially formulated pre-colored talc-filled Maxxam™ PP material incorporating OnCap™ CTR Process Optimization Additive.
