polycondensates. As with all reactive extrusion you need to have proper mixing and energy input for best results.” Both Nexamite R201 and R405 are offered in masterbatch form. Evonik says that its organo-modified siloxane technology can be used to improve compatibility of distinct polymer domains, improving properties such as elongation at break, impact strength, stress crack resistance, and weld line strength, as well as processability. “The organo-modified backbone is allowing recycled polymers mixed with our compatibilisers to have improved moulding properties, higher throughput, and even a higher surface quality of finished products (shark skin prevention, surface smoothness, etc.),” says Ido Offenbach, Americas Segments Manager for Specialty Additives. “While already commercial with two of our solutions, TEGO XP 21024 (used for PP-in-PE compatibilisation) and TEGO XP 21025 (PE-in-PP, but also PA-in-polyolefin compatibilisations), we are continuing our investigations into new compati- bilisers that are even more versatile – particularly between hydrophobic and hydrophilic polymer domains.”
