RIGID POLYURETHANE FOAM
6# DENSITY
The TC-300 A/B 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. Also
available in 3# and 10# densities.
e Easy to hand mix or machine cast Flows well into mold cavities
Fast Demolds * Excellent physical properties :
