Additives for polyamides and polyesters

Plastics that must meet high require­ments need support: Under the trade name BRUGGOLEN® we offer special high-perform­ance addit­ives for tech­nical plastics with an emphasis on poly­amide (PA 6, PA 6.6, PA 12, and copoly­amide), including heat, processing, and light stabil­izers, processing aids, and modi­fiers. BRUGGOLEN® polymer addit­ives can be used in injec­tion molding and extru­sion, as well as in the pack­aging industry and fiber industry. These polymer addit­ives ensure effi­cient processing as well as an improved service life for plastic parts, and they offer high quality on econom­ical terms. Our polymer addit­ives are readily avail­able as indi­vidual products or combin­a­tion products (One-Packs). One-Packs are ready-mixed compounds of two or more addit­ives and they are tailored to special solu­tions and applic­a­tions. One-Packs are avail­able as powder, compactate, or master batch, and in this regard help to save almost half of the additive raw mater­ials.

Heat Stab­il­izers

For many mater­ials the phys­ical prop­er­ties and the appear­ance of the plastic are in some cases consid­er­ably changed through the influ­ence of heat, light, and atmo­spheric oxygen. In this regard a distinc­tion is made between processing stabil­izers that primarily coun­teract polymer degrad­a­tion in the melt phase (compounding, injec­tion molding, extru­sion), long-term stabil­izers that prevent polymer degrad­a­tion under increased ambient temper­at­ures (60 - 130°C) during finished part use, high-temper­ature stabil­izers that are effective up to 180°C, and UV stabil­izers for effective protec­tion of finished parts against polymer degrad­a­tion by through UV radi­ation. Combin­a­tions of different addit­ives provide addi­tional synergy effects.

Processing Agents for poly­amides and poly­es­ters

With its processing agents, Brügge­mann supports poly­amide compounders in cost-effi­ciently improving the processing char­ac­ter­istics of poly­amides. In this way, the flow­ab­ility of poly­amides rein­forced with glass fiber, for example, can be increased and their good mech­an­ical prop­er­ties can be retained. Such highly-satur­ated poly­amides are an outstanding replace­ment for metal in tech­nical parts.
