  • EXP27110

An easy to use Rigid Expanding Foam, it is a low density, rigid foam system which may be used to manufacture mouldings. It is also suitable for structural infill of fibreglass components, and relies on the thorough mixing of two low viscosity liquids by either hand or machine mix techniques. The foam is produced by the mixing together of the two Components A and B at a ratio of 1 to 1.06 by volume, or preferably 1 to 1.2 by weight - however it can be mixed 1:1 for ease of use.

 

1kg of mixed part A & B expands to approximately 1 cubic foot.

 

This product contains no CFC's or HCFC's and therefore has an Ozone Depletion Potential (O.D.P.) of zero.

 

Cream Time: 25-35 seconds (from start of mixing to start of rise)
String Time: 150-170 seconds (from start of mixing to when a thread can be drawn from rising foam with an inserted rod)
Rise Time: 180-230 seconds (from start of mixing to end of rise)
Tack Free Time: 300-360 seconds (from start of mixing till surface can be lightly touched without foam sticking)
Density (Free rise); 48 - 50 kg/M3 (weight of cups contents divided by volume of cup)
Core Density: 41 - 43 kg/M3 (density of piece cut from foam core)
Ratio: 1:1.2 (by weight)
