Applications of antioxidant Antioxidant 246 / 333
- Mainly used as rubber anti-aging agent, antioxidant, because the molecular weight is larger than the antioxidant BHT, so the thermal volatility is lower, the heat resistance is better.
- it is a high-efficiency stabilizer, can be used as natural rubber and various synthetic Anti-aging agents such as BR and SBR can also be used in latex and polyolefin plastics.
- It can be used to prevent the acid value and viscosity of lubricating oil, fuel oil and biodiesel from rising
- it can effectively prevent yellowing of resin, adhesive and curing agent during storage and use, and improve product stability and weather resistance.
- It is also the main raw material for the preparation of phosphite antioxidants 633, 641.
