White or light yellow powder.It is soluble in ketones, esters, tetrahydrofurans and chlorinated hydrocarbons. Excellent chemical resistance. Poor thermal stability and light resistance, more than 100℃ or long time exposure to sunlight began to decompose hydrogen chloride, plastic manufacturing needs to add stabilizer. Electric insulation is good, will not burn.
