Uses: SperseStab-2300 is used as an antioxidant for polyethylene pipe, wire and cable, tubes as well as greenhouse films. This unique antioxidant performs well with peroxide cured systems and functions as a disproportionation agent for rosin esters.

In addition it functions as an anti-scorch agent in TDI based polyurethane systems and an anti-skinning agent in hot melt adhesives.

Due to its chemical structure, SperseStab 2300 is not readily adsorbed / absorbed into the carbon black like other antioxidants resulting in superior performance.
