Appropriately selected WAXOLINE® polymer-soluble dyes give excellent all-round performance in: PS (Polystyrene), SAN, ABS, PMMA, PC, PETP and PETB, POM, unplasticised PVC and PPO. WAXOLINE® solvent dyes contribute resistances (strengths) against different phenomena that affect dye’s performance.

  • Light fastness: persistence of a colour after having received a certain amount of UV radiation.
  • Chemical fastness: colour resistance in chemically aggressive environments (acidic or basic).
  • Heat fastness: colour resistance to temperature, mainly during processing.
  • Migration fastness: migration of pigment.


What is WAXOLINE® Solvent Dyes used for?

WAXOLINE® Solvent Dyes are widely used and applied in the world of pyrotechnics.

These dyes can be mixed with agents that act as fuel (oxidizers and reducers / gunpowder) that when ignited, transfer this heat to the metal atoms of the dyes and the respective color is generated according to the metal atom that makes up that dye.

How can be divided the chemistry of fireworks?

  • Explosion:  It occurs from an Oxidation-Reduction reaction between oxidizing agents, such as chlorates (ClO4-) or nitrates (NO3-) and reducing agents, such as Sulfur or carbon (C, S). This generates a lot of heat (exothermic rate) and this heat is key to the generation of color. Metallic pigments enhance this phenomenon, providing more rumbling or other acoustic modifications.
  • Color generation: Metallic salts or other metallic compounds (Cu, Li, Na…) are added. The heat generated by the reaction causes these salts to emit color according to the energy absorbed by the metal atoms. This energy causes an excitation of the electrons of the metallic atoms, which, when they relax, emit the characteristic color of each metal (Cu (copper) blue, Na (sodium) yellow, Li (lithium (red)…). This process can be divided into: Luminescence and Incandescence
