Compound antioxidant B225

　　Antioxidant B225 not only plays a role in processing stabilization but also plays a role in heat stabilization. It is a compound of the compound synergistic stabilizer of the main antioxidant 1010 and the auxiliary antioxidant 168. It is soluble in organic solvents such as benzene, chloroform, cyclohexane, ethyl acetate, etc., but insoluble in water.

　　Appearance: white or light yellow crystalline powder

　　Solubility: clear

　　Volatile matter: ≤0.2%

　　Transmittance: 425nm≥96%; 500nm≥97%

　　Antioxidant SK-168 content: 45.0%~55.0%

　　Performance advantages:

　　The compound antioxidant B225 is a classic mixture. The content of phosphite is relatively high, which can meet the thermal stability during plastic processing. B225 has the following advantages in its application range:

　　Maintain the original melt index.

　　Low color pollution

　　Significantly improve long-term stability.

　　Features and uses:

　　This product is an antioxidant with good performance, widely used in polyethylene, polypropylene, polyoxymethylene, ABS resin, PS resin, PVC, PC, adhesive, rubber and petroleum products. It has outstanding processing stability and long-term protection for polyolefin. Through the synergy of antioxidant 1010 and antioxidant 168, the thermal and oxidative degradation of plastics can be effectively suppressed. Used together with light stabilizer 662, light stabilizer 770, and light stabilizer 994 in polyethylene shed film, it has good anti-aging performance. Compound antioxidants can be used in polyolefins, polyamides, linear polyesters and ABS. The general dosage is 0.1%～0.8%.

　　Storage and packaging:

　　The compound antioxidant B225 is non-toxic, non-flammable, non-explosive, non-corrosive, and has good storage stability. Net weight 25kg/drum (bag).
