Physical properties:

Soluble in acetone, benzene, chloroform, cyclohexane, ethyl acetate, n-hexane and toluene, sparingly soluble in methanol, insoluble in water. Good compatibility with most substrates, low volatility and high resistance to extraction

 

Performance and Application:

Antioxidant FWEOX 76 is a highly effective, non discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation. It can be applied in polyolefins, polypropylene, polybutene-1 as well as in other polymer such as engineering plastics, styrene homo-and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. The product can be used in combination with other additives such as costabilizers (e.g.thioethers,phosphites,phosphonites), light stabilizers and functional stabilizers. The amount to be used may be 0.05%~0.5%.In polyolefins, 0.1%~0.4%, in styrene homo-and copolymers, 0.1%~0.3%, in hot melt adhesives, 0.2%~1.0%, in adhesives, 0.1%~0.5%.

Storage and packaging:

 

Keep containers tightly closed in a cool, well-ventilated place. Paper-plastic composite bags or cardboard boxes with PE film bag inside, net weight 25kg, or according to customers’ requirement. Period of Validity: Normally 24 months.
