Product description

Silicone foam Closed Cell 6 - Thick fluid

The Silicone Foam Closed Cell 6 is a 2-component (Platinum) Poly-Addition casting silicone that cures at elevated temperature and foams up to 6 times its volume. This silicone can of course also be colored with silicone dye. The increased temperature is necessary for a better foam effect.

This silicone is used for filling seat cushions, for props and decor and for filling flexible objects and bras, pillows and mattresses, etc. Foam plates/foam mats are also made with this silicone. Silicone foam is also suitable for sealing electronics and Lithium batteries (application testing is necessary).

The spreadability makes this silicone better suited for the production of foamed sheets than the more fluid version.

  • High frothing
  • Returns well to intended shape after pressing
  • High temperature and chemical resistance
  • Easy to process
  • Uniform/well distributed density over the entire casting.

Technical data

  • Mixing ratio by weight: A:B = 100:100
  • Processing time (pot life) at 25°C: 3 minutes
  • Demoulding time at 60°C: 50 minutes
  • Viscosity at 20°C: 50,000 mPa S
  • Colour: Whitish, colourless
  • Hardness: Shore C 2-50 (Shore A 30-85) depending on foaming
  • Density at 20°C: 0.166 g/cm³
  • Frothing factor in volume: 6
  • Flame retardant UL94-HB
  • Closed Cells

Please note: Pot life/demoulding time is highly dependent on temperature! At a higher temperature, the processing time and demoulding time become shorter. Frothing factor is highly dependent on temperature. Process the product at the indicated temperature to obtain the described properties.

Processing 

These silicones can easily be mixed by hand or machine. Mix the A and B components carefully and in the indicated ratio (100 parts A and 100 parts B by weight). Process the mixture within the pot life and wait until it has completely hardened before demoulding. The foaming effect only works at elevated temperatures (From 60 oC)


Please note, the faster the silicone hardens, the less the foam effect. The silicone hardens faster at higher temperatures, so the foam effect cannot fully occur. Silicone that is too cold also gives a less good result because the foam formation then starts to collapse again.
So preferably process the silicone at the indicated temperature.

Working in a closed mold produces a more uniform foam mass.

Extra information

You can color the silicone intensely with silicone dye .

Please note: This is a silicone addition. These silicones can be poisoned by sulfur, nitrogen, amino compounds and metal salts. If you are not sure whether the products you are using (including gloves, spatulas and cups) contain these ingredients, do a small test first. These substances are found in many latex gloves, some plastilines, lacquers and glues, condensation silicone, 1-component silicone sealant, natural rubbers and 3D printing material (especially stereolithography). If you still want to use this, you will have to put on a protective layer of polyvinyl alcohol .

Shelf life

Provided the silicone is stored in closed packaging, cool and frost-free, the shelf life is at least one year.

Safety requirements

If you frequently work with silicone, it is recommended to wear gloves during processing and to ventilate the area well. For safety instructions, please refer to the safety data sheet.
