Toys Toys: latest news

Toys Toys: latest news lower (but constant) to that of ABS, and may cause an issue if there is no opportunity to adjust molds for parts assembled with very tight tolerances. However, normal industrial tolerances should accommodate most slight shrinkage differences. Specific density is also higher at 1.18 g/m³ compared to 1.04 g/m³ for ABS. However, the combination of high strength and rigidity means that some wall-thinning can be considered. Testing bars, of course, are always injected under highly controlled conditions to obtain optimum properties, but injecting real parts is not always that simple. Injecting intricate parts with ribs, openings and other design features can always bring potential knit or welding lines issues where two material flows meet at a precise point in the part. In such cases, lower impact values can be encountered, especially with less miscible polymer-additive combinations. In fact, impact welding line resistance became a major focus of Solegear’s later-stage research to address conditions under which only 25 to 35% of the IZOD value was obtained. With further iterative testing and a number of modification to conditions at laboratory and semi-industrial scale, Solegear’s research team devised a proprietary solution that exceeded the Izod target value without scarifying other properties. An optimized and patent protected family of highly bio-based formulations has been created and added to the Solegear’s existing portfolio of durable bioplastics. The Traverse XD family includes XD1000, an extremely high bio-based (98%) formulation with high mechanical resistance, ductility and high heat resistance. Traverse XD1010 delivers the super tough performance with slightly lower bio-based content (85%). For more cost-conscious applications, Traverse XD1020 is an entry level formulation with lower bio-based content (55%). All bio-based content has been independently tested using ASTM D6866 standards or ISO 16620. After intense development in lab-scale and on small industrial compounding lines, Solegear’s XD formulations are commercially ready for production environments where specific parts and applications can be evaluated for processing stability and performance at full scale. Having met the most stringent demands within the toy industry itself, these formulations can be applicable to other high performance markets where stakeholders are thinking of making a significant breakthrough toward sustainability. A new generation of extra durable bioplastics with high bio-based content to replace fossil fuels is no longer only in our imagination; it is becoming a reality for visionary companies who are ready to take the next big step towards a bio-based economy. www.solegear.ca Innovation award for Bioblo Bioblo a young startup – company fromTulln, Lower Austria, recently received the International Green Product Award. The product: Bioblo, a novel play and construction brick made from 100 % renewable resources that is meant to capture the imagination of young and old. More than 400 submissions from 21 countries were judged by an international jury according to the criteria design, innovation and sustainability. At the end, the three young entrepreneurs from Tulln were in the lead as a newcomer in the category Kids. As justification for the top position, the innovative material, the unique design and the high educational value of Bioblo blocks were cited. Bioblos are made of mixture of wood and 100% renewably sourced Green PE (by Braskem). The material is thus 100 % free of oil, CO 2 -neutral and fully recyclable. The compound was developed at the Institute of Natural Materials Technology if the IFA Tulln (Department of Agrobiotechnology at the University of Natural Resources and Life Sciences, Vienna, Austria) and sets new standards in the field of ecological toys. The compound consists of 60 % wood chips from local, PEFC certified forestry and either 40 % biobased Green-PE or recycled polypropylene from recycled beakers. The plastic content is limited to the minimum necessary amount in order to fulfill the legal requirements on stability and water resistance. The TÜV certified colorant masterbatches are added directly during injection molding, which replaces a subsequent dyeing or painting, and eliminates the problems associated with such decoration methods (staining, chipping). The design of Bioblos resembles a perforated honeycomb shape which is a resource-efficient but at the same time very stable and visually appealing design. The size of the blocks is selected so that there are no swallowable small parts, and high towers can be built in a short time. Unlike wooden blocks are Bioblos washable and therefore suitable even for intensive and long time use (for example, in nurseries and schools). www.www.bioblo.com References: [1] N.N.: Proposition 65, Safe Drinking Water and Toxic Enforcement Act of 1986 (http://oehha.ca.gov/proposition-65/law/proposition-65-law-andregulations) [2] http://www.lego.com/en-us/aboutus/news-room/2015/june/ sustainable-materials-centre [3] N.N.: PHA for safer toys, bioplastics MAGAZINE, issue 01/2016 [4] New PLA formulations to replace ABS, bioplastics MAGAZINE, Issue 03/2015 34 bioplastics MAGAZINE [04/16] Vol. 11
