Parlon (chlorinated rubber, Chlor-Rub™, Superchlon™, chlorinated isoprene) White powder.
Parlon is a common chlorine (68%) donor, fuel, and color enhancer for colored flames and star compositions. Solvents are acetone and xylene.
Other chlorine donors than parlon are shown on the left. Since different chlorine donors have different percentages of chlorine in them and have different fuel values, they may not be interchangeable.
Here are some pyrotechnic compositions that use parlon:
