TC-300 10# Rigid Polyurethane Foam

The TC-300 polyurethane foam system is a series of rigid, closed cell foams available in a variety of densities.  The TC-300 can be easily mixed by hand in small batches using a rapid, vigorous mixing action or by using a Jiffy Mixer® in a drill to provide a high-shear mix in small to large quantities. For low to high production, these foam systems can also be machine dispensed using BJB’s Centerpointe Meter-Mix equipment.  Cured parts can be sanded, stapled, painted or stained within a short time after demolding.

NOTE: Density is based off of free-rise, unrestricted samples. Typical castings in a closed mold with back pressure will increase density and reduce expansion rate. This will often require up to 1.5 to 2.5 times more foam than theoretical calculated amount of foam for a given volume and mold shape/goemetry. Also temperature of liquid foam, relative humidity, and mixing technique (hand stirred vs jiffy mix with a drill) will also affect expansion rate of foam.
