ADEKA PALMAROLE offers a full range of solid and liquid primary and secondary antioxidants.

Physical blends of stabilizers with different stabilization mechanisms are the state of the art today. The overall effect of two stabilizers combined is better than what would be expected based on the sum of effects of each component alone.

Antioxidant Blends
ADK STAB A-514 is a synergistic antioxidant blend of ADK STAB A-50 and ADK STAB 2112, suitable for processing and long term thermal stabilisation for all plastics.
Antioxidant Blends
ADK STAB A-611 is synergistic antioxidant blend of a hindered phenolic antioxidant with a phosphite co-stabilizing antioxidant, suitable for processing and long term thermal stabilization for all plastics.
Antioxidant Blends
ADK STAB A-612 is synergistic antioxidant blend of a hindered phenolic antioxidant with a phosphite co-stabilizing antioxidant, suitable for processing and long term thermal stabilization for all plastics.
Antioxidant Blends
ADK STAB A-614 is synergistic antioxidant blend of a hindered phenolic antioxidant with a phosphite co-stabilizing antioxidant, suitable for processing and long term thermal stabilization for all plastics.

Phenolic antioxidants are radical scavengers which prevent thermal degradation of many organic materials such as polymers. Their effectiveness increases when used in combination with phosphites, thioethers and light stabilizers.

Phenolic Antioxidants
ADK STAB AO-30 is an efficient UVA, suitable for engineering plastics such as PA, PMMA, POM, rigid PVC, TPE compounding and rubber.
Phenolic Antioxidants
ADK STAB AO-40 is an effective antioxidant for long term thermal stability in ABS and rubbers. High performance antioxidant for engineering plastics and elastomers.
Phenolic Antioxidants
ADK STAB AO-50 is a highly effective and versatile, low melting antioxidant for all plastics and elastomers. ADK STAB AO-50 shows good compatibility with most common polymers and is a good substitute for BHT.
Phenolic Antioxidants
ADK STAB AO-60 has a high molecular weight and is a highly effective thermal and process stabiliser with low volatility.
Phenolic Antioxidants
ADK STAB AO-80 is a high molecular weight type highly effective hindered phenolic antioxidant that has low volatility and excellent gas fading resistance.
Phenolic Antioxidants
PALMAROLE AO.OH.330 is a highly effective, sterically hindered phenolic antioxidant for the stabilization of polymers.
Phenolic Antioxidants
CCP STAB 390E is an excellent antioxidant with the advantage of a pumpable liquid. Offers low volatility, low fogging  and favorable compatibility, particularly recommended for polyols, polyurethanes and textiles.

Phosphites are efficient decomposers of hydroperoxides that are formed during the autooxidation of polymers. Phosphites are especially used in melt processing where they are added in blends with hindered phenolic antioxidants. Such combinations are more effective than hindered phenol alone.

Phosphites
ADK STAB 1178 is a low cost conventinal type phosphite.
Phosphites
ADK STAB TPP is a liquid phosphite which provides excellent color and heat stability for thermoplastics.
Phosphites
ADK STAB 135A is an organophosphite processing stabilizer.
Phosphites
