In many cases, bio-based additives are comparable to, or even outperform, fossil-based additives. One of these examples is the replacement of hydrocarbon waxes such as paraffin, Fischer-Tropsch and polyethylene waxes. Compared with petrochemical-based lubricants, the bio-based alternative is slightly more compatible to the polymer resulting in a better distribution over the surface. This, in turn, can offer cost benefits since it is worth evaluating to utilize these additives in lower dosages.
Another example is the alternative to montanic wax and its derivatives. Montanic wax is extracted from brown coal through the use of hazardous chemicals in the refining and bleaching processes. A very limited number of sources for montanic waxes resulted in a severe shortage about one decade ago. Although the shortage has now been overcome, the number of sources is still small. However, multiple LOXIOL® products can successfully be used as alternatives. They are free of montanic compounds, but offer similar performance. And, through use of renewable sources, Emery Oleochemicals can offer security of supply of these products to the compounder, masterbatcher or polymer processor.
Renewable LOXIOL® and EDENOL® plastic additives are not just a passing trend. They are backed by over 60 years of technical expertise and plastics industry knowledge. The pioneers of this technology are also its ongoing innovators: Emery Oleochemicals. Extension of the Technical Development Center
Extruder at the Technical Development Center in Loxstedt, Germany
To comply with the increasing requirements of the market, the Technical Development Center (TDC) in Loxstedt, Germany has been extended once again. Here, products are tested and the beneficial effect of additives is adjusted and improved. Besides laboratory synthesis, product batches up to 70 kg (154 lbs) can be produced in the pilot reactor. Moreover, a new injection molding machine and various measurement instruments are part of the new equipment. This investment strengthen Emerys position as a competent and thus valuable development partner, and enables the development of products tailored for the respective production process. Recent Product Developments LOXIOL® A 7
- An internal antifogging agent based to 70 % on natural raw materials. It is incorporated directly into the plastics in the dryblending step. LOXIOL® A 7 shows optimal compatibility in PVC-formulations and an improved antifog effect compared with standard products. It has been successfully tested in cold fog and hot fog applications. The reduced pour point ensures an easy handling at cool warehouse temperatures.LOXIOL® AF 80
- An external antifogging agent based to 100 % on natural raw materials. It is applied onto the finished plastics product, such as films or sheets, as a water or solvent based solution. It can also be used as part of the coating. The advantages of external application are that it does not affect the characteristics, such as viscosity, of the polymer melt. It is also possible to treat small lots of plastic products, and much lower dosages are needed compared with internal application. LOXIOL® AF 80 is suitable for plastics such as PET, PC, or polyolefin LOXIOL® AF 90
is an antifogging agent free of animal-derived materials. It is suitable for polyethylene and polypropylene films. LOXIOL® AF 90 shows excellent hot and cold fogging test results in both polypropylene types. Especially in cold fogging applications, it shows superior performance compared with other additives offered as antifogging agents. LOXIOL® 3290
is an internal antistatic agent based to 100 % natural raw materials. It is suitable for rigid PVC applications, such as films and sheets. LOXIOL® 3290 is designed to be incorporated into the plastics material in the dryblend or compound. After the thermoplastic conversion like extrusion, injection molding or calendering, the additive migrates to the plastics surface to avoid the buildup of static charge. Residual antistatic agent in the polymer bulk serves as a reservoir in case the material at the surface is removed in any way. LOXIOL® 3290 shows a very good antistatic performance, has food contact approval and a much lower impact on the transparency of the finished article compared with alternative products, such as paraffin sulfonates. Metal and Ceramic 3D Printer Filaments
With more than 25 years of experience in metal injection molding, Emery Oleochemicals has developed a binder system that can be used for almost every sinterable powder. The process properties of the feedstock such as flowability, release effect, rigidity and flexibility can be adjusted by tailoring the binder composition. The solvent as well as the green and brown part scrap can be recycled, which makes Emerys binder system most sustainable. The Green Polymer Additives team will demonstrate their binder system for 3D filament print by printing various metal and ceramic parts directly at their booth A 58 in Hall 8b. See firsthand the advantages of Emerys binder system at the K fair in Düsseldorf.
