ELASTOSIL® R 512/70 OH

ELASTOSIL® R 512/70 OH is a peroxide curing HCR silicone for the manufacture of silicone-insulated safety cables that maintain circuit integrity in case of fire.


Properties

In case of fire ELASTOSIL® R 512/70 OH forms a ceramic-like layer with high insulation resistance, good mechanical stability and low smoke formation.

 

The color of the rubber base is beige. Colors will not match the RAL color codes of the masterbatches used in paste or pellet form in the compound (pastel colors).

 

ELASTOSIL® R 512/70 OH is also available as 2-component-system (ELASTOSIL® R 512/70-1 & -2). The advantage is that the properties of the compound can be adjusted easily by modifying the mixing ratio of component -1 & -2 for the particular application.

 

This product can be used within a temperature range of - 55 °C to + 210 °C.
