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 aerate 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

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.
