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.
