Elkem (Bluestar Silicones) BLUESIL™ RT FOAM 3241 A & B Silicone Foam
Categories: Polymer; Thermoset; Silicone; Silicone Foam

Material Notes: Description: BLUESIL RT FOAM 3241 A&B is a two-component silicone foam which cures at room temperature by an addition cure reaction. When the A and B liquid components are thoroughly mixed in a 1:1 ratio, the product expands and cures to a foamed elastomer at room temperature.

Applications: This product is specifically formulated for the production of printing rollers. Other suggested applications are:

  • Automatic installation of gaskets for the automotive and domestic appliance industry. Insulation of noise and heat.
  • Cushioning and damping when high temperature variation is involved.
Advantages:
  • Easy curing: BLUESIL RT FOAM 3241 A&B crosslinks at temperatures above 20ºC, even in the complete absence of air or humidity.
  • Easy processing thanks to the simple 1:1 mix ratio.
  • Good chemical and temperature resistance.
  • Low hardness (Shore 00).
  • Low compression set.
  • High temperature stability.
  • The material expands without employing ozone depleting CFCs or other related blowing agents.
