Suzorite

Suzorite® mica Improved fire resistance and mechanical properties in rubber compounds

Suzorite® mica is an effective flame retardant extender and ideal all-round multi-functional additive, prized for its reinforcement properties, for increasing HDT and flexural modulus, and for reducing shrinkage and warpage.

Suzorite® is a platy phlogopite mineral which is chemically inert and provides high thermal stability.

Suzorite® is ideal for replacing ammonium polyphosphate (APP), a halogen-free flame retardant system used in polyolefins.

Loading levels of 30-35% APP are commonly used to meet UL94 requirements such as V-0 ratings. However, APP is expensive and diminishes physical properties such as tensile strength. Replacing up to one third of APP flame retardant with Suzorite®:

  • Provides reinforcement
  • Boosts tensile properties
  • Improves material integrity
  • Improves char promotion and afterglow time

This combination of properties allows formulators to maintain fire and mechanical performance in electrical applications.

Suzorite® is ideal for non-color sensitive applications. For color sensitive applications, please contact us.

We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
