Enhance clarity and performance of crystalline polymers such as polypropylene.

Nucleating masterbatches contain organic compounds that during the cooling phase of the melt, facilitate the crystallization of polymer chains.

Higher crystallinity offers rigidity, increases the softening temperature, imparts improved clarity, and helps achieve faster production cycles.

Nucleating/Clarifying masterbatches are commonly used to enhance the properties of Polypropylene materials.

Typical applications: polypropylene packaging and containers.

Improve light stability of polymers against UV radiation.

Light-induced degradation of polymers is a result of the combined action of oxygen and UV radiation. Exposure of polymeric materials to UV can lead to deterioration of morphological and physicochemical properties.

Usual results are yellowing, cracking, chalking, and inferior mechanical properties due to the changes in the chemical structure of the molecules.

Light stabilizers are employed in order to inhibit photodegradation by either absorbing the harmful part of radiation or by interfering with the chemical reaction of photooxidation and preventing its propagation.

Various blends of UV stabilizers are available, suitable for each specific application and material type.

Typical applications: greenhouse and mulch film, construction and insulation materials, fibers, tapes, exterior furniture and equipment, automotive parts, engineering plastics.

Improve stability of polymers against thermal degradation and aging.

The constant exposure of polymers to oxygen during their production, processing, and use leads to gradual oxidation.

This is especially the case for post-consumer recycled materials or regrinds that can be subjected to intense heating and mechanical stresses multiple times.

Oxidation affects the chemical structure of polymers and can lead to poor mechanical and optical properties. Certain types of plastic are more susceptible to oxidation than others and require specific additives in order to be processed successfully.

Such additives are primary and secondary antioxidants that inhibit oxidation during the life cycle of the finished good as well as during thermal processing and thus protect the plastic from aging.

Typical applications: containers, packaging, films, fibers, tapes, construction and insulation materials, exterior furniture and equipment, automotive, engineering plastics.

Promote dispersion by enhancing material compatibility.

Polymers are often blended with various types of fillers, additives, reinforcing materials and other type of polymers. Τhis is especially the case for recycled materials.

Because of their different chemical structure, those materials are usually immiscible.

This behavior can lead to phase separation during melt processing, poor dispersion and inferior mechanical properties affecting the quality of the final product.

Compatibilizers promote interfacial adhesion and facilitate the dispersion of the immiscible phase, thus enhancing the performance of the finished good.

Typical applications: highly filled polymers, polymer blends, recyclates.

Inhibit bacterial growth on polymer surfaces.

Antibacterial masterbatches contain metal ions that are released within the polymer mass.

Those ions are attracted to cellular walls of bacteria that come in contact with the plastic and inhibit their enzymic activity, hence preventing them from multiplying.

Typical applications: food and beverage containers, kitchenware, trash containers, and disposable medical equipment.

Reduce contact between polymer films.

Antiblock masterbatches implement inorganic synthetic or natural minerals that modify the surface properties of polymers.

At low dosages the additive helps form air pockets between film surfaces that prevent adhesion and blocking during processing and handling.

The main component does not affect the transparency of the film, is non silicotic, and has food contact compliance.

Typical applications: film, flexible packaging.

Enhance clarity by eliminating droplet formation on polymer surfaces.

Intrinsic hydrophobicity of most common polymers leads to droplet formation on their surface when in contact with humidity.

Reduced clarity has an unpleasant aesthetic result and can create performance issues, especially in the case of agricultural film.

Antifog masterbatches facilitate the formation of a water-thin film on the polymer surface instead of droplets.

This helps the material retain its clarity and enhances its performance in humid environments.

Typical applications: greenhouse film, transparent food containers, packaging.

Used for moisture absorbing during processing and product life cycle.

Desiccant masterbatches incorporate hydroscopic inorganic substances, that are able to adsorb and retain moisture even in low levels of relative humidity.

They offer easier processing for hydrophilic polymers and PCR materials with high water content and eliminate problems related to moisture.

Additionally, desiccant masterbatches are employed in packaging applications for when dry atmosphere during storage is critical for content preservation.

Typical applications: processing polymers with high water content, containers.

Eliminate unpleasant odors.

Odor absorbers contain special organic agents that help eliminate unpleasant odors released during processing and decomposition.

The molecules of the odor absorber attach to volatile compounds and deactivate them rather than just covering them.

Typical applications: recyclates, trash bags, and containers.

External and internal lubricants that promote material flow and reduce friction.

Slip and Mold release additives are vegetable-derived compounds that act as external lubricants by migrating to the polymer surface and modifying its properties.

They offer benefits such as faster processing, improved melt flow, lower coefficient of friction, anti-scratch properties, and facilitating the release of injected items from the mold.

Typical applications: film, flexible packaging, caps, containers, and engineering plastics.

Reduces polymer to metal friction and facilitates material processing.

PPA act as a lubricant in very low concentrations, by forming a thin film on the equipment surface.

By doing so it creates a lubricating layer that reduces the polymer to metal friction.

They help improve the melt flow, reduce required torque, prevent die buildup, and eliminate melt fracture and shark skin on film surfaces during extrusion.
