HandiFoam® System 120 Slow Rise Refillable Kit (P23301)
The HandiFoam System 120 Slow Rise Refillable Kit is a closed-cell, low-pressure polyurethane foam solution made for professionals requiring a slow-expanding, flowable system for deep voids and structural fills. Its slow rise time allows full cavity fill without creating pressure that could warp, distort, or damage materials.
Perfect for OEM and specialty applications, this refill system features an HFO formulation with low Global Warming Potential (GWP), making it both efficient and environmentally responsible. Common use cases include wall cavities, bathtubs, shipping containers, door cores, vehicle and trailer panel insulation, and more. Due to its gentle expansion profile, it’s also used in restoration, taxidermy, and custom fabrication work.
