Antiox AHM EC is a synergistic blend of various non-staining antioxidants, including primary phenolic stabilizers, thio-esters for the long term stability and phosphites for high temperature protection. The physical form of the components is primarily (but not completely) dusty in order to facilitate the dissolution / melting of the product.

Functions: Antioxidant

Chemical Family: Blends & Combinations, Phenols & Phenolics, Phosphorous-based Compounds, Thioesters

Features: Low Dusting, Temperature Resistance

For hot-melt adhesives, ANTIOX AHM-EC is very efficient at the following concentrations.

  • Thermoplastic rubbers like SIS, SBS: 1.2-1.5% on rubber content.
  • Ethylene-vinylacetate: 0.3-0.5% on EVA content.
  • Thermoplastic polyurethanes: 0.2-0.4% on PU content.
  • Polyamides: 0.5-1.0% on PA content.

For solventborne adhesives, ANTIOX AHM-EC is very efficient at the following concentrations:

  • Natural rubber, SBR, chloroprene rubber, polyisoprene, butyl rubber: 0.25-0.5% on dry content.

ANTIOX AHM-EC can be added directly to the compound, either together with other recipe ingredients, or predispersed into one of them, or dissolved (for solvent solutions).
In hot-melt continuos system (by extrusion process) it is advisable that a liquid component (like liquid rosin esters or naphtenic oil, etc.) is used to give some tack to the surface of granules, in order to have a fair distribution over the total mass.
