Description

Antioxidant

Product Description:

Antioxidant 168 ( CAS:31570-04-4) is a high-efficiency phosphite-type secondary antioxidant and polymer processing stabilizer.
It can effectively decompose hydroperoxides generated during high temperature extrusion, injection molding and pelletizing processes, greatly reducing melt yellowing and thermal degradation of plastic products.
Antioxidant 168 is not recommended to be used alone. When compounded with hindered phenol primary antioxidants like Antioxidant 1010 or 1076, it delivers remarkable synergistic stabilization performance for plastics, rubbers, elastomers and adhesives.
It is a cost effective alternative to imported Irgafos 168.
Key Advantages
·Excellent anti-yellowing performance during high temperature polymer processing
·High purity ≥99.0%, stable transmittance ≥97%, bright finished product color
·Low volatility, little odor under high temperature working condition
·Good thermal stability and moderate hydrolysis resistance
·Wide compatibility with polyolefins, engineering plastics, rubber and adhesives
·Available in both powder and granule forms, fit for different feeding process
·Batch by batch strict inspection; independent COA report supplied for every shipment
·Export grade waterproof neutral packing, suitable for long distance sea transportation
·Perfect substitute for imported Irgafos 168 with competitive cost
