Material News Bright colours for more green on the blue planet Sustainability is on everyone's lips, and the German company GRAFE from Blankenhain is also involved in the development of specific masterbatches for corresponding applications. "We have been working on the colouring of biobased and home-compostable materials for some time now", reports Lars Schulze, Head of Colour Development and Material Sciences. "We were able to successfully establish the first projects on the market and commercialise them. We have gained extensive experience and done a lot of development work. We will continue to push forward the projects with a sustainable character". Home compostable coffee capsules in brilliant colours Home compostable products meet the highest standards of environmental protection, according to the company. For example, the company has successfully coloured coffee capsules in a very elaborate development project. "Given the strict guidelines according to which the masterbatches may only contain certain ingredients and the pigments can only be used in limited concentrations, this is quite a demanding task. Nevertheless, we succeeded in over-colouring the dark base material, explains Schulze. In the end, the colours maroon, light grey, brilliant blue, blue-grey, petrol brilliant, olive brilliant, violet brilliant as well as beige and berry were used from Grafe's Modalen range. The certification came into effect on 14 August 2020. Sustainable developments continue "We are currently working on PHBV projects", Schulze reports. This is a home compostable, nontoxic, biocompatible plastic that is produced naturally by bacteria and offers a good alternative for many non-biodegradable, synthetic polymers. "Besides the difficulties of the biopolymers currently on offer, in terms of processing, inherent colour and temperature resistance, another major challenge is their colouring or over-colouring. Both the plastic base material and the additives should have as little impact on the environment as possible and be biodegradable in order to achieve the certification goals", explains the expert. The specialists at Grafe are guided by EN 13432 for this purpose, which severely limits the pigment selection and dosage. "That is why very brilliant colours are the current challenge for our development team. But we also want to solve these in the future", announces the Head of Colour Development and Material Sciences and lists numerous applications – such as disposable articles and everyday product packaging. We look forward to new project requests to continue contributing to more green on the blue planet". MT www.grafe.com LANXESS offers new sustainable composites LANXESS (Cologne, Germany) introduces new Tepex thermoplastic composites that are currently being developed starting from recycled or biobased raw materials. “With these construction materials, we want to help our customers to make more sustainable products that have a smaller carbon footprint, conserve resources, and protect the climate”, explains Dirk Bonefeld, Head of Global Product Management and Marketing for Tepex at Lanxess. Recently, the specialty chemicals company has launched a fully biobased composite material based on flax and polylactic acid on the market. Tailor-made for structural lightweight design Development is about to be completed, for example, on a matrix plastic based on polyamide 6 for Tepex dynalite, that is produced starting from “green” cyclohexane and therefore consists of well over 80 % sustainable raw materials. As a result, the plastic meets the requirements that Lanxess has set for its new “Scopeblue” range. It consists of products that contain a significant proportion of circular (recycled or biobased) raw materials or have a carbon footprint that is considerably smaller than that of conventional products. When the matrix plastic is reinforced with continuousfibre fabrics, the resulting semi-finished products exhibit the same outstanding properties as comparable, equivalent products that are purely fossil-based. The semi-finished products with a green matrix are therefore suitable for applications in structural lightweight design that are typical for Tepex dynalite – such as front-end carriers, seat shells, or battery consoles. Biobased alternatives to polyamide 12 Another development focus is new matrix solutions for Tepex based on recycled thermoplastic polyurethane (TPU) or polyethylene terephthalate (PET) as well as on biobased polyamide 10.10. The recycled TPU products are primarily intended for sports equipment. One of their strengths is their good composite adhesion with many other injection-moulded materials when processed using the insert moulding or hybrid moulding methods. The semi-finished products with a PET recyclate matrix are a cost-effective alternative to virgin polycarbonate and polyamide, for example. The PET comes from used beverage bottles and is also available in large quantities thanks to the closed recycling chain for these bottles. The biobased polyamide 10.10 is derived from castor oil. “The composite materials made with it are a sustainable alternative to polyamide 12 composites because they have similar mechanical characteristics and a comparable density”, says Bonefeld.

New and Sustainable BioAcetate S70 BioAcetate S70 is an eco-friendly and high-performing alternative material that is non-toxic and free from harmful phthalates. BioAcetate S70 uses renewable resources and is biodegradable according to ISO 14855. The five main ECO-Advantages of BioAcetate S70 are as follows: 1. ISCC Sustainability Carbon Certification 2. 62 % biobased according to ASTM-D6866 3. Biodegradable according to ISO-14855 4. Harmful plasticizers free (NO DEP) 5. Biocompatibility according to ISO-10993 As the primary application, the material is ideal for injection moulding applications and handmade acetate frames production that is well-suited for high-end optic and eyewear frames. Other applications include household applications, electronic cigarette parts, smartphone covers, as well as watch parts. BioAcetate S70 aims to be a material that is better for Earth and better for performance.

The expanded offering for film extrusion, thermoforming, and injection moulding is in line with Green Dot Bioplastics’ goal to achieve faster rates of biodegradability in ambient conditions, while meeting the growing sustainability demands of brand owners and consumers. These new compostable materials are an integral part of the company’s extensive bioplastics portfolio which includes biocomposites, elastomers, and natural fibre-reinforced resins all produced at the company’s newly expanded manufacturing facility in Onaga, KN, USA. “This launch culminates our extensive development of a new category of compostable materials for single-use applications and packaging markets”, said Mark Remmert, Green Dot Bioplastics CEO. “We’ve successfully developed unique materials that have a faster rate of biodegradation in ambient composting conditions and the functional performance that the market demands”. The five new film grades are compostable starch blends that require no tooling or process modifications when run on traditional blown or cast film equipment. Among them are Terratek BD3003 which exhibits high puncture resistance and tear strength and is heat sealable like linear low-density polyethylene (LDPE) film. Meanwhile, Terratek BD3300 is a stiff, highmodulus material with high heat resistance and overall properties similar to HDPE film. The film grades deliver faster rates of biodegradability for home composting, industrial composting, and soil biodegradability. They are targeted for a range of applications including produce bags, bubble wrap, agricultural films, and other lawn and garden packaging. The film materials are completing third-party certification by TÜV Austria, a leading European certifying agency. Green Dot’s new compostable offering also includes three new thermoforming grades which provide a range of properties including clarity. Other grades provide higher heat performance and greater flexibility for applications such as food service packaging, takeout containers, deli packages, and straws. The thermoforming grades are also completing final certification by TÜV Austria. Two injection moulding grades round out the new compostable offering. They deliver higher heat performance and enhanced processability (lower cycle times) for caps/closures, food service ware, and takeout containers. In a breakthrough application development effort, Green Dot worked with a customer to commercialize a living hinge design for an injection moulded package. The physical and mechanical properties of typical bioplastic resins have not previously allowed the moulding of a living hinge capable of hundreds of flexural openings and closures while delivering mechanical properties necessary for a polypropylenetype enclosure.
