Due to the good plasticization, TCEP is widely used in cellulose acetate, polyvinyl acetate, nitrocellulose lacquer, ethyl cellulose, PVC, polyurethane, and phenolic resin, which all have a self-extinguish ability.
With the addition of TCEP, their physical properties are improved and tactilities feel soft. Moreover, TCEP is a main flame-retardant material to produce polyurethane for flame-retardant cables, anti-corrosion tarpaulin, and flame-retardant rubber converter belts.
TCEP is also called petroleum additive and extractant of rare-earth elements.
