Organic Synthetic Intermediate O-Phenylphenol OPP CAS 90-43-7 For Flame Retardant DOPO
Introduction of o-phenylphenol
Since the polymer material containing organic phosphorus compound forms a graphite-like carbonized film on the surface of the material during combustion, the polymer is isolated from the air, has good flame retardant properties, high flame retardancy, low volatility, oil resistance and hydrolysis resistance. Good properties, more and more widely used, and will gradually replace the inorganic and halogen-containing flame retardant materials used today. Using o-phenylphenol as raw material, a new type of phosphorus-containing flame retardant intermediate DOPO can be synthesized.

Features of 2-Phenylphenol :
2-hydroxy-biphenyl for polyvinyl chloride fiber hydrophobic synthetic fibers, polyester
and other vector staining using the carrier, surfactant, sterilizing preservatives, dyes intermediates.
In Japan, 2-hydroxy-sodium biphenyl and citrus for mildew. The wax mixed with 0.8% of the goods,
spray in the citrus harvest, and may also use biphenyl and could rot Portland to a minimum. Britain,
the United States, Canada allows the use of larger scope of fruit, including apples, pears, pineapple,
etc.. The products are also used as preservatives cosmetics. 2-hydroxy-biphenyl rat oral LD50 of 2.7-3.0g/kg.
