Flexible Foam 8463 is a soft and flexible two-part urethane which foams in place to form a soft, squeezable, closed-cell foam.
Since it is so soft, Flexible Foam 8463 will expand to fill the available cavity, but will not exert excess pressure on the walls of the cavity.
This is very different from the rigid foams you are used to, which can exert high pressures as they expand and cure.
When cured this foam is very soft, and will remain soft.
In automotive applications, it is designed to replace OEM's flexible foams found on door intrusion beams, roof bows, inside body panels, pillars, and in other automotive body cavities when repairs are made.
In marine applications, this foam is useful for sealing openings and cable pass-throughs in engine and other compartments for soundproofing purposes.
Flexible foams, like this 8463, are much better at absorbing sound and vibration than rigid expanding foams.
Expands to 10 times its original volume to fill large cavities with a small amount of material.
