Kenrich mixes waste plastics with cement
Salvatore Monte, President of Kenrich Petrochemicals, a company that for many years has been a prominent developer of compatibilising tech- nologies, continues to plough a particular furrow. In March of last year, at a German plastics recycling forum, he presented a paper called “Repoly- merisation and compatibilisation of thermoplastics in post-consumer recycling processes by using titanate ester catalysts.” On the same day, he was issued with US patent application 0071230, “Construction materials, compositions and methods of making same” in which he demonstrates compatibilisation of ordinary Portland cement and water with hydrocarbons. Monte and several partners are

working on the application of waste plastics in asphalt roads. In another project, Monte is working with Patrick K Simpson, President of PKS Consulting, under an NDA to develop a sound approach to converting plastics ocean waste into useful products. Monte says he sees
compared to virgin material.” A new grade, Acti-Tech compatibiliser 16MA11F with food contact compliance, will be commercial- ised this year to enlarge applications for packaging and recycling industries. It can be added to polyole- fin-based formulations. Le Piouff adds: “We are still exploring new applications fit for our product range.” NGC recently expanded in the Asia-Pacific area,
via Nordic Grafting & Compound Solutions (NGCS), a production and commercialisation joint venture set up in late 2019 together with its sister company, Customised Compound Solutions (CCS) and Chongqing Techxanadu Industrial. Polyscope Polymers, which specialises in
styrene-maleic anhydride (SMA) polymers, offers compatibilisers, as well as chain extenders and other functionalities, within its Xibond blend optimiser portfolio. It also includes viscosity modifiers, coupling agents, and surface modifiers. “Xibond additives are like the luxury spices of a polymer recipe,” says Ardy Doelen, Sales and Business Development Manager. Xibond compatibilisers optimise surface tension and blend morphology to prevent phase separation in mixes of different polymers. “This is particularly useful for returning recycled PC/ABS – a plastic blend widely used in automotive and electronics applica- tions – to its original state,” says Doelen. Similarly, Xibond chain extenders connect polymer chains to increase a material’s molecular weight, which improves viscosity, processability, and melt strength.

PCR still struggling on many fronts, but the prospect in the USA of “mandated content [is] a ray of light. However, PIR continues to gain traction in the area of polymer blends and adding known recycle content to virgin polymer.” Monte will be inducted into the Plastics Hall of Fame in October.
To help R&D managers choose the right Xibond
product for their needs, Polyscope offers an online selector tool that provides instant recommenda- tions based on the required functionalities. In the near future, it plans to add a dedicated functional- ity page on its website. Polyscope also recently launched Xibox, a pre-screening service that trials different Xibond formulations for its customers, helping accelerate their development processes. Doelen says Polyscope views its initial portfolio
as a starting point and hopes to expand it in the near future. “Our long-term goal is to offer solu- tions for a wider range of materials, such as polyolefins. To achieve this, we’ll keep working with our customers – through partnerships, mergers and acquisitions, and joint ventures – to add new products that support their needs.”
