Additives / Masterbatches Biobased additives that enhance polymer processing and improve end product quality With more than 60 years of experience delivering high-performance, natural-based products to the plastics industry, Emery Oleochemicals GmbH (Düsseldorf, Germany; headquartered in Telok Panglima Garang, Malaysia) is well-positioned to offer natural-based polymer additives, especially lubricants, plasticizers and surface finish agents to companies in the plastics industry that are seeking more sustainable products. Why Green Polymer Additives? Due to the plastics industry’s heightened interest in sustainability, Emery Oleochemicals is also constantly refining its Green Polymer Additives product portfolio to exceed the increasingly stringent standards and regulations. From the very beginning, when the LOXIOL ® brand was first introduced in 1957, Emery’s experienced product development teams around the globe have concentrated on creating specialized additives through the use of renewable biobased raw materials from natural fats and oils. Lubricants for Optimal Processability Loxiol lubricants from Emery Oleochemicals are compatible with various stabilizers and are mainly based on renewable raw materials. Loxiol G 59 improves the material flow during extrusion and reduces the melt viscosity. It has food contact approval and is suitable for transparent applications. It is compatible with several polymers and it reduces the formation of deposits (blooming) on the final article as well as on the machines (plate out), and thereby, it increases the productivity. Loxiol G 24 is an external lubricant and release agent that is based on 100 % renewable resources. It can replace paraffin and Fischer-Tropsch waxes. Sustainable Additives for C-PVC It is well known in the plastics industry that the processing behavior of C-PVC is significantly different from that of PVC. To meet these unique application requirements, Emery Oleochemicals’ latest technical developments include tailored ester lubricants for processing of chlorinated PVC (C-PVC). Advantages of Emery’s new lubricants are, among others, a biobased-feedstock, a minor influence on the Vicat softening point and a defined chemical structure similar to the often used paraffin waxes. These lubricants also enable an exact adjustment of the processing window. In addition, Emery’s most recent product developments include food contact compliant additives that adhere to the respective regulations in all major regions worldwide. Customized Solutions to Meet Today’s Challenging Applications In addition to a broad portfolio of established products, Emery Oleochemicals offers customized products that are not only eco-friendly, but also tailored to the desired performance specifications. as well as economically viable,” emphasizes Dr. Harald Klein, Global Platform Head of Emery Oleochemicals’ Green Polymer Additives business unit. In addition to a broad portfolio of established products, Emery Oleochemicals offers customized solutions tailored to special requirements. “Today, it is not enough to provide standardized products. Plastics manufacturers require additives that are not only eco-friendly, but also customized to their performance specifications as well as economically viable,” emphasizes Dr. Harald Klein, Global Platform Head of Emery Oleochemicals’ Green Polymer Additives business unit. Emery Oleochemicals’ global operations are supported by a diverse workforce and an extensive global distribution network covering over 50 countries worldwide.

Additives / Masterbatches Renewable, sustainable mineral By: Jeff Apisdorf President MultiPlast Systems, Inc. Solon, Ohio, USA Multiplast Systems, Inc. (Solon, Ohio) recently introduced a range of masterbatches made with RenewCal, a renewable biogenic, highly purified oolitic aragonite (calcium carbonate). This unique mineral has physical and environmental characteristics unlike all other mined alternatives. Compatible with a wide range of resins, including biobased resins, RenewCal masterbatches offer a wide range of benefits including performance, economics, environmental and degrading in both flexible and rigid products. Sourced in their 500 square mile lease on the Bahama Banks, this unique crystalline formed mineral is replenished by approximately 900,000 tonnes per year. Current supply of this accumulated material is over 2 billion tonnes. The natural biogenic process is based on a confluence of factors, including ocean currents, sea-floor topography, and the natural presence of picoplankton stimulated by photosynthesis, which cause these microscopic organic organisms to combine atmospheric carbon dioxide with pure calcium in the water, to form oolitic aragonite. These oolites then precipitate as very pure grains of calcium carbonate, which settle on the ocean floor. This continuing natural mineralization process is also, at the same time, sequestering 5,680 tonnes of CO 2 from the atmosphere. Unlike mined minerals which vary based on the range of sources, RenewCal is very consistent. as it is produced from the same source under the same conditions. Harvested with minimal environmental impact, RenewCal is proven to be carbon minimal to negative, renewable and sustainable. Environmental benefits include replacing fossil fuel-based resins, lowering carbon footprint compared to mined minerals, and producing finished products with a higher degree of renewable content. Benefits of improved degradability/compostability are due to RenewCal’s ability of high Ph buffer against acids, for higher loadings and for greater mineral surface area, which all speed up the degradation process. Benefits in production, performance, and economics are due to its unique crystalline needle like particle shape, high zeta potential (improved dispersion), ability to load high percentages depending on the application and cost reduction by replacing more expensive resins. Improved barrier characteristics and heat deflection are achieved by its high aspect ratio, crystalline particle shape and high loading thus producing a greater tortuous path. RenewCal masterbatches are FDA compliant for food packaging, come in a range of carriers and can have mineral content up to 80 %. Typical applications are flexible film, thermoformed sheeting, blown and injection molding, synthetic paper and extrusion coatings. COMPEO Uniquely efficient. Incredibly versatile.
