Safety & Health

Safety Note
  • During vulcanization of ELASTOSIL® N189 BLACK, a total of 4% by weight of an oxime is being split off. These vapors should not be inhaled for long periods or in high concentration. Work areas should therefore be well ventilated.
  • Contact of unvulcanized silicone rubber with eyes and mucous membranes must be avoided as this would cause irritation. However if it does happen, rinse the affected area thoroughly with water.
