Millad® NX® 8000 ECO is an additive that delivers crystal clear glass-like clarity, while extending sustainability benefits in the production of clarified PP parts, by offering faster production rates and average energy savings of 10%. Brand owners using PP clarified with Millad NX® 8000 ECO can display a UL Environmental Claim Validation label on their injection molded parts.
Consistent look in modern lighting
In retail, there is a continuing rapid shift to LED lighting, a trend that impacts how products look to customers. Millad NX® 8000 ECO maintains a consistent, fresh appearance in all retail lighting, regardless of the presence of UV light from the light source.
Good for Recycling
Millad NX® 8000 ECO is recognized by the US Association of Plastic Recyclers for its compatibility with plastic packaging recycling. Suitable for all conversion processes, it makes clarified polypropylene a viable alternative to glass or amorphous polymers like PC, PET, PVC, and PS.
- UL Environmental Claim Validation label
- Certification for plastic packaging recycling by RecyClass
- Faster production and up to 10% energy savings
- Suitability for food contact applications
How Millad® NX® 8000 Works
As the polypropylene crystallizes from the melt, complex macro-structures known as spherulites form. These are responsible for scattering light and their size dictates the polymer’s optical and physical characteristics.
To improve clarity, the spherulite size must be reduced. Insoluble nucleating agents are used, but their effectiveness is limited as the nucleator itself causes a haze and their insolubility leads to non-uniform dispersion.
Millad NX 8000, clarifying agent solubilizes in the molten polypropylene and precipitates from the melt upon cooling, to form a fibrous network whose surface becomes the nucleation site for the PP. This surface creates a very high nucleation density, forming tiny crystallites that are too small to scatter light. The fibers themselves are also too small to scatter light.
Why choose Millad NX 8000?
Traditional clarifiers require a minimum temperature of around 220°C before they will dissolve in PP. At this temperature, the fibrous network is not properly formed, preventing high transparency. Millad NX 8000 has improved solubility characteristics in PP which allow processing at lower temperatures. This creates a broader, more robust processing window and a dramatic improvement in the clarity of polypropylene.
