It is a typical organophosphorus flame retardant. After the addition of TCEP, the polymer has the characteristics of moisture, ultraviolet and antistatic in addition to self-extinguishing ability.
Suitable for phenolic resin, polyvinyl chloride, polyacrylate, polyurethane, etc., can improve water resistance, acid resistance, cold resistance, antistatic property. It can also be used as metal extractant, lubricant and gasoline additive, and polyimide processing modifier. Lithium batteries commonly used flame retardants.
This product is packaged in galvanized drum, net weight of 250 kg per barrel, storage temperature between 5-38℃, long-term storage, can not exceed 35℃, and to keep the air dry. Keep away from fire and heat. 2. It should be stored separately from oxidants, acids, alkalis and edible chemicals, and should not be mixed.
