AO-B900 is a two-component antioxidant system made from:
This pre-blended solution is highly effective in stabilizing polyolefins and engineering plastics exposed to high temperatures and extended service conditions.
| Property | Typical Value |
|---|---|
| Composition Ratio | AO-1076 (30%) + AO-168 (70%) |
| Form | White to off-white powder or granule |
| Melting Point | 80 – 105 °C |
| Recommended Dosage | 0.2 – 0.8 phr |
| Thermal Stability | Excellent up to 280 °C |
| Compatibility | Good with fillers, UVs, FRs |
| Common Issue | AO-B900 Advantage |
|---|---|
| Polymer degradation during extrusion | AO-1076 stabilizes against melt oxidation |
| Product failure under heat aging | AO-168 slows down long-term degradation |
| Complex additive blending | Pre-formulated and easy to dose |
| Yellowing or discoloration | Clean, non-staining performance |
Q1: What makes AO-B900 better than single antioxidants?
The combination of AO-1076 + AO-168 delivers both short-term and long-term protection, reducing the need for separate stabilizers.
Q2: Can it be used with UV absorbers or HALS?
Yes. AO-B900 works well with light stabilizers in outdoor applications.
Q3: Is it suitable for flame retardant plastics?
Yes. It is compatible with halogen-free and phosphorus-based FR systems.
Q4: What forms are available?
We offer powder, granule, and masterbatch formats based on your processing needs.
Q5: How should it be stored?
Store in a cool, dry area. Avoid sunlight and moisture. Use within 24 months
