- Applications
- Charmax™ LS ZB400 is an effective flame retardant synergist and smoke suppressant in halogenated polymers, particularly PVC, acting in the condensed phase as a charformer. Charmax™ LS ZB400 can act as a partial replacement of Antimony Oxide and is also used in specific applications in polyethylene, epoxies, unsaturated polyesters and rubber. Typical uses include jacketing and insulation for plenum and riser cables, wall coverings, and urethane foams, fiber reinforced polyester composites, coatings & sealants.
