Features & Benefits

Advantages Over Conventional Antimony Trioxide Systems
  • Free-flowing particles for exceptional consistency, better mixing and easy processing.
  • Non-pigmenting for light transmission.
  • Reduces pigment loading for mass tone colors.
  • Maintains brilliant color of fluorescent pigments and dyes.
Function

BurnEx ZTA replaces antimony trioxide as a flame retardant synergist in vinyl plastisols, injection molding compounds and calendar compounds. BurnEx ZTA is a sodium-neutralized material with an alkaline surface. It will absorb metallic ions and is used where acidic materials interfere with other properties.
