Welcome to Imerys Performance Minerals PLASTICS Home Plastics Expertise Environmental Benefits News & Events Breadcrumb Home Your Market Plastics Biopolymers BIOPOLYMERS Imerys minerals boost the performance of bioplastics for durable applications Imerys provides a wide portfolio of engineered minerals to meet bioplastic requirements. Imerys minerals are 100% natural and inherently biocompatible making them the ideal agents for boosting the mechanical properties of rigid biopolymers, allowing them to be used in demanding applications such as durable packaging, automotive parts and electrical applications. They make excellent nucleating agents, allow density reductions and opacity in bioplastic films, and improve compostability. Rigid bioplastics Biopolymer reinforcement filler Imerys minerals make ideal reinforcement fillers in rigid bioplastics such as polylactic acid (PLA) and polyhydroxyalkanoate (PHA). Imerys minerals: Increase biopolymer stiffness Improve biopolymer dimensional stability, reducing shrinkage and thermal expansion Increase heat deflection temperature Improve barrier properties Are food contact approved Lower the carbon footprint of the final product For rigid plastics, we particularly recommend: High performing HAR®, Jetfine® and Steamic® talcs Suzorite® and MU101 mica products Biopolymer nucleating agents Imerys talcs such as our Steamic® grades are ideal nucleating agents in PLA, where they speed up crystallization, reduce molding time and production costs, whilst maintaining dimensional stability. Biopolymer films In BOPLA film applications, our Supercoat® 70S engineered calcium carbonate is an excellent solution for achieving density reduction and high opacity due to its ability to promote cavitation and microvoid formation during orientation. Compostable PHA Our engineered calcined kaolin product, Eco-Delink™, has proved effective for accelerating biodegradability of PHA. Eco-Delink™ also improves the processability of PHA in terms of heat diffusion, melt strength and tackiness. Foamed biopolymers Micro-lamellar Mistrocell® is an outstanding nucleating agent for foamed bioplastic composites. Synthetic polyester Using Supercoat® 70S in biodegradable synthetic polyester demonstrates improvement in bubble cooling, improved or maintained mechanical properties, while improving cost optimization. We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
