Omnistab AN1138 is a new generation Antioxidant suitable for most polymers. It can prevent the forming of peroxide during the storage of coatings and polyolefin  and also prevent scorch during foaming process.Omnistab AN‐1138 has low volatility and good compatibility, which is perfect choice for polymer manufacturing in single liquid,emulsion, suspension liquid and other solutions.Omnistab AN‐1138 shows  outstanding performance during forced air cooling. This feature can be used in automobile products against surface fogging and strengthen the textile coloration.Omnistab AN‐1138 is easy to be emulsified, which could keep liquid form or in dispersible or dissolved state during manufacturing processs. It can be added before,after or in polymerization process.
