Application
ANTIOXIDANT 300 is a non-staining and non-discoloring hindered thiophenol antioxidant. It is used as an antioxidant in HDPE and LDPE for water and gas pipes and high voltage cables. It has high resistance to thermo-oxidative degradation and wash-out, exhibits excellent compatibility with peroxides and exhibits great synergism with carbon black.
ANTIOXIDANT 300 is also used as a polymerization and processing stabilizer for PP, ABS, PVC, EPDM elastomers and polybutadienes. It is effective as an anti-skinning agent for hot melt adhesives, an anti-scorching agent for polyurethanes during condensation of TDI on polyesters, and a heat stabilizer for lubricants
