BIO-BASED POLYMERS | MATERIALS


fibre from the original production. LNP Thermocomp DC0041PE-7M1D145W is


produced in Asia Pacific, with plans to expand local production to other geographies, as needed, says SABIC. Durabio, developed by Mitsubishi Chemical


Corporation (MCC), is a partially bio-based polycarbonate made from plant-derived isosor- bide. The supplier says it features excellent performance, offering higher resistance to impact, heat and weather than conventional polycarbon- ate. Additional benefits include: ease of colouring, to create glossy, highly reflective, and rich-hue surfaces; and hardness, enhancing durability and scratch resistance. These advantages eliminate the need for painting or coating, thus cutting costs and VOCs. MCC says the results of a recent life cycle assessment for Durabio resin suggest that by using Durabio, Global Warming Potential is reduced by 30% compared with polycarbonate, by 35% compared with PMMA, and by 60% compared with PA6. MCC launched Durabio in 2013 and says that since then it has been adopted in many Japanese and European cars, for both interior and exterior parts. Keiichiro Kanatani, Business Development Manager, America, for Durabio, says: “Recently, Durabio has also been used in the large front grilles. Furthermore, MCC is developing various technologies in cooperation with customers [and] Durabio is beginning to be used for high-value- added decorative parts such as two-colour mould- ed parts, silver metallic parts, and matte parts.” Kanatani also expects Durabio to be used for sensor covers, owing to its high radar transmittance as well as high weather and scratch resistance. In fact, it has already been adopted for radar covers on three trucks produced by Isuzu. MCC is also


working with customers on development of transparent exterior panels to replace heavier glass panels. Arkema says that it is on track to begin produc-


tion of Rilsan PA11 at a new plant in Singapore in the first half of next year. The plant, for which production will be 100%-derived from renewable castor beans, represents a 50% increase in Arke- ma’s global PA11 capacity. “When complete, this will represent the biggest integrated bio-factory in the world dedicated to high performance poly- mers,” says Arkema. End-use sectors for PA11 include EVs, consumer goods, electronics, sports and lifestyle markets. Arkema has announced plans to buy Agiplast in


Italy, a leader in the regeneration of high perfor- mance polymers, in particular specialty polyamides and fluoropolymers, and its historical partner in recycling operations. “With this acquisition, Arkema will be the first fully integrated high performance polymer manufacturer offering both bio-based and recycled materials in order to address the chal- lenges of resource scarcity and end-of-life prod- ucts,” says the company. The deal is expected to close in June.


Phone accessory company PopSockets was look- ing for a way to make its products more sustainable and in April, it launched a new line, PopGrip Plant, made with DSM’s bio-based Arnitel Eco copolyes- ter TPE and EcoPaXX PA410. “Arnitel Eco delivers high performance, through a wide portfolio of grades that thrive in extreme conditions, while EcoPaXX delivers performance, aesthetics and sustainability, which are all key features of the PopGrip application,” says DSM. The application is a small retractable grip that fits on the back of a mobile phone. “It seems very simple at first glance, but not just any sustainable material would work,” says Geert Vanden Poel, the project’s application development engineer. “The grip contains multiple parts that must expand and
