Antioxidant Blends for Plastic Compounds

BRUGGOLEN® TP-H1606 by Brüggemann is a new non-discoloring copper complex based heat stabilizer. It acts as a high performance antioxidant. BRUGGOLEN® TP-H1606 is developed for polyamides and significantly improves the long-term stabilization over a broad temperature range. It is a non-dusting blend which is easy to handle and process and allows an improved alternative to phenolic based stabilizer blends as it greatly extends the exposure time especially in the low to medium temperature range, where the phenolic blends have represented the industry standard. It can be used for PA injection molding and extrusion applications.

GC B225 by Greenchemicals is a blend of tetrakismetilene (3-(3,5-di-t-butyl-4-hydroxyhydrocinnamate) methane and tris (2,4-di-tert-butylphenyl) phosphite. It acts as an antioxidant.

• It is suitable for the stabilization of polyamides as it guarantees excellent process stability and very high thermal stability that lasts over time.
• It is recommended for polyefins (PE & PP), polyamide, polycarbonate, PBT and ABS.
• The components of the GC B225 are authorized for food contact applications.

Rhenogran® ZMMBI-50 by Rhein Chemie Additives (Lanxess Group) is a non-staining anti-oxidant for vulcanizates based on natural- and synthetic rubber such as SBR, IR and NBR. In combination with other anti-oxidants, it provides synergistic and outstanding protection from rubber poisons. It affords good protection against oxidation and contains EPDM as a polymeric binder. It is suitable for transparent, white and colored rubber goods, e.g. home and leisure articles, fabric proofing and toys. It is also applicable for goods that must withstand heat when used with thiuram, but little or no sulfur. Rhenogran® ZMMBI-50 has a shelf life of 2 years.

Vanox® 945 by Vanderbilt Chemicals is a blend of antioxidants. It acts as a scorch inhibitor for polyurethane foams.
