The Danish company Plastix recycles old fishing nets and ropes. The granules produced are used by JSP International, among others, to manufacture expanded polypropylene (EPP).

11 % of the plastic waste in the sea comes from the maritime industry. For the recycling of old fishing nets and ropes, accurate sorting is very important

Weight reduction is one of the major requirements of automotive components. Regardless of the vehicles in which they are used. One of the lightest materials that can be considered is polypropylene (PP).

Higher mechanical properties with lower density make polypropylene an interesting alternative to polyethylene for a large number of applications. New catalysts and production processes offer a wider range of products. Monolayer films and recycling are under development. In the meantime, China consumes almost one-third of the PP produced worldwide.

The ReOil pilot plant at OMV AG in Schwechat, Austria, converts plastic wastes with poor recycling properties into cracker raw material, and hence into potential monomers

Polypropylene (PP)

To ensure better stability of expanded polystyrene insulation panels on the house wall, they are fastened with an additional polypropylene (PP) anchor. However, the fact that two different materials are used results in thermal bridges due to different thermal conductivities (TC), which can be seen visually as the formation of mold and algae, but also cause energy losses. The motivation for this work was to adjust the WLF of the two materials by using a filler, but not to negatively influence the mechanical strength of the anchor.

Milliken & Co., Ghent, Belgium, has developed a new variant of its well-established Millad NX 8000 clarifying additive for polypropylene that it has tailored for use in the extrusion blow molding (EBM) process. This new additive performs significantly better in higher melt-flow-rate (MFR) grades of PP, and yields excellent results in both optics and productivity.

After the explosion of developments in polymer formulations over the last year, it is worth taking a closer look during Fakuma at details such as functional additives or application-specific modifications. Overall, lightweight design continues to spur development but defined surface characteristics are also in demand. The reported innovations do not just follow current consumer trends but also provide ideas for advanced product and process developments.

Polymers Can Be Expected Everywhere 

Lightweight is no longer just a matter of replacing metal. More and more often, plastics already in use are substituted by lighter weight polymers. New low-density compounds exhibit not only good materials and processing properties. On top of that, they offer various secondary advantages, such as are illustrated by an engine room bulkhead cover and a car door sill.  

Reducing Density and Part Weight via the Material without Altering Existing Processes 

Strong Flyweights 

The many different additives in plastic compounds make their composition extremely complex. Special stabilizers help to prevent the generation of volatile organic compounds (VOCs) resulting from the interaction of components in subsequent, long-term automotive applications.

Whether it was the motto presented by the trade fair’s committee or threatened prohibition proceedings: material producers are getting more involved with sustainability. While some are participating in campaigns and initiatives, others are investigating more closely the basis of their raw materials and their products. In view of the challenge to create a circular economy for plastics, all other topics take second place this year.

About Drivers and the Driven

Milliken & Company will begin production at its new clarifier plant in Blacksburg, SC/UDS, in the fall.

With increased production capacities, Milliken considers itself well equipped to meet increasing demand for clarifiers.

Milliken Increases Clarifier Capacity

Milliken & Company will be showcasing its product portfolio of polymer additives and colorant capabilities at booth 01/A22 at Interplastica 2022 in Russia.

Milliken & Company, a manufacturer of polymer additive and colorant capabilities, continues to broaden the range of sustainable solutions it offers to help customers improve their resin formulations, compounds and end products. The company will be showcasing this growing product portfolio at booth 01/A22 at Interplastica 2022 in Russia.

Milliken’s Millad NX 8000 ECO clarifier is the latest addition to its market-leading Millad NX 8000 product range, used to produce the durable, fully transparent, highly recyclable material known as NX UltraClear PP. Millad NX 8000 ECO offers the added benefit of faster production rates, contributing to average energy savings of 10% for the production of clarified polypropylene (PP) parts – independently certified by Underwriters Laboratories (UL). The U.S.-based Association of Plastic Recyclers also recognizes the ECO grade for its compatibility with plastic packaging recycling. The technology is fully compatible with PP recycling processes in Europe and poses no recyclability issues, according to RecyClass, a cross-industry initiative that works to advance plastic packaging recyclability.

Several Milliken additives reportedly serve to enhance polypropylene’s performance properties. One such product is its Hyperform HPN family, certain grades of which will be on display at Interplastica.

<ul><li> Hyperform HPN 715 maximizes stiffness without sacrificing impact, offering convertors a viable option to replace engineering plastics with cost-effective PP materials in demanding applications such as automotive components and appliance parts.</li><li> Hyperform HPN 909ei offers improved aesthetics for thermoformed parts made in PP homopolymers and mini-random copolymers. It is also developed with a cleaner chemistry to address concerns related to migration, especially in food-contact applications such as food trays and drink cups. Moreover, it has one SML (Specific Migration Limit) less than the previous generation of product.</li><li>Hyperform HPN 500ei not only provides high stiffness but also improves optics to thermoformed homo-PP products (i.e., drink cups and lids etc.), making these parts looking cleaner, fresher and clearer.</li></ul>

Enhancing the Impact Strength of Recycled Polypropylene

The DeltaMax Performance Modifiers for PP contribute to a circular economy by enhancing the impact strength and melt-flow properties of recycled polypropylene (rPP) resins, blends and PP impact copolymers (ICPs), in many cases elevating them to the levels of virgin resins, or beyond. In particular, DeltaMax 5000a allows resin producers to balance the properties of ICP resins more effectively and thereby increase their overall performance. DeltaMax-modified resins can maximize impact strength and melt flow without compromising stiffness performance. This enables compounders and converters to incorporate up to 100% recycled PP without sacrificing performance or processing.

The DeltaFlow Viscosity Modifiers, meanwhile, specifically help recyclers by increasing rPP’s melt flow rate for the extrusion and injection molding processes, thereby enabling converters to reduce cycle times, boost productivity and improve processability.

Milliken’s KeyPlast colorants for plastics are versatile products that can be used by liquid and solid masterbatch producers, resin producers and compounders, and are suitable for use with a wide range of polymer and resins systems. Of particular note is the FDA-compliant KeyPlast colorant range for polyethylene terephthalate (PET), which can be used to create distinctive shades in both transparent and opaque applications. Ideal of food-contact applications, this range is well suited for beverage bottles, pharmacopeia containers, and for products that require differentiated design.
