Application Details

Processing

  • The raw rubber requires the addition of a platinum catalyst for vulcanization at elevated temperatures. A homogeneous incorporation is a must, but please avoid temperatures >30°C along the incorporation process in order to maintain best processing behavior.
  • Pot life is depending on the used catalyst and storage condition. ELASTOSIL® R plus 5305/70 and ELASTOSIL® AUX PT 1 are homogeneously mixed in a ratio of 100 : 1.5.
  • Care must be taken to keep the compound cool during mixing. Crosslinking begins when ELASTOSIL® AUX PT 1 has been added. The rate and degree of crosslinking depend on the storage time and temperature. At 23 °C the mixture has a pot life of about 24 h. This can be extended by storing the catalyzed mixture at a lower temperature.
