BIOPLASTICS | MATERIALS
are claimed to feature high stiffness, strength and impact resistance as well as a pleasant surface texture. This makes them particularly suitable for use in injection moulded technical parts and articles in daily use. As Biograde compounds do not contain any restricted plasticisers, they are also approved for food contact (EN 10/2011 and FDA) and for the production of toys (EN 71-3). The company has also developed Terraprene PP
grades – polypropylene compounds for injection moulding applications, which are partially based on renewable raw materials. The renewable content of the various grades is about 35% and can be demonstrated to the final customer by the 14C method. Their processing and application proper- ties are similar to those of comparable petroleum- based materials, the company says. FKuR adds that Terraprene also has applications in thermoplastic elastomers. Depending on the grade, the share of renewable resources can be as high as 80%. The performance features and resistance of these newly developed bio-based types largely correspond to those of their petro- chemical counterparts. They are suitable for both injection moulding and extrusion. The currently
available standard types of Terraprene cover a wide Shore hardness range from A 20 to D 40. In addition, individual adjustments based on the customer’s requirements are possible. Typical applications include soft touch handles, toys, tools, and sports equipment. Terraprene is also a sustain- able substitute for PVC. Italian company Bio-on has accelerated the construction of its new research hub due to rising demand for special PHA (polyhydroxyalkanoates) biopolymers. Opening is set for April 2018, several months ahead of schedule. By the end of the year,
