TRIPOR 224 High Density
*Tripor 224* is a high 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.
Tripor 224' contains no CFC's or HCFCs and therefore has an Ozone Depletion Potential (O.D.P.) of zero.
Foam Manufacture
The foam is produced by the mixing together of the two Components A and B at a ratio of 1 to. 1 by weight. In hand mixing the Component A should be pre-mixed for at least one minute to aereate it, before mixing with the Component B.
After mixing, the foam should be immediately transferred to the mould or cavity to be filled, pouring should be finished before there is any significant amount of expansion.
The foam should be processed between the temperatures of 18 - 25°C. The following times are typical for an ambient temperature of 20°C (68°F). Lower temperatures will give slower reaction, higher temperature faster. Reaction times will also be affected by the bulk mixed, larger amount will give shorter times, small amounts longer times.
Mixing Time 40 seconds
Cream Time 75 seconds (from start of mixing to start of rise)
Tack Free Time 450 seconds (from start of mixing
till surface can be lightly touched without foam sticking)
Rise Time 350 seconds
(from start of mixing to end of rise)
Core Density (Free rise) 175kg/M3 weight of foam piece
cut from test block divided by volume of foam piece)
Ratio 1:1.1 (by weight)
STORAGE & HANDLING
It is extremely important that the drums should be re-sealed immediately after use to prevent the entry of moisture which will adversely affect the resultant foam.
The shelf life of the materials is four months when stored in sealed drums within the recommended temperature range of 10 • 30°C, but users are recommended not to hold in stock longer than necessary.
