| Product Description: Magnesium carbonate (MgCO3) is an effective raw material finding use in many applications. In rubber, magnesium carbonate can be used as an extender in rubber bands, rubber thread, and for an application where a translucent compound is required. The recommended level of loading is from 5 to 40 parts on the rubber polymer. Generally, as the loading is increased, the modulus will also increase. MgCO3 provides reasonably good reinforcement with minimal reduction in rebound and resilience. In flame resistant applications, MgCO3 has been shown to produce more char than ATH or Mg(OH)2. Magnesium Carbonate will reinforce more than ATH and Mg(OH)2 and as a result will raise compound viscosity proportionally. It is an excellent compounding agent to reduce smoke and flame propagation where the mechanism of action is moisture release and CO2 emissionInformation provided by Akrochem Corporation |
