Omnistab AN 1425
Omnistab AN 1425 is a high molecular weight, multifunctional phenolic primary antioxidant for processing and long-term thermal stabilization. It contains phosphorus and is highly efficient, non discoloring stabilizer for organic substrates. Offers protection against thermo-oxidative degradation and high resistance to extraction. Also, used as esterification catalyst for the preparation of rosin esters. It is compatible with polyolefins, polyesters, and crosslinked elastomers (e.g. NBR). It is recommended for applications requiring improved extraction resistance, low volatility, excellent color and color stability and superior gas-fading resistance. It can be used alone or in combinations with other Omnistab stabilizers and co-stabilizers. The recommended concentration is 0.05-0.25 %.
