PF4 Doors & Windows PU Foam

Short Description:

PF4 Multi-functional and economical foam sealant single-component polyurethane foam sealant has excellent properties such as sealing, heat preservation, heat insulation, moisture-proof and insulation. The volume of this product expands rapidly after ejection, and it can be freely filled according to the shape of gaps and voids. After curing, the bubble holes are delicate and have good elasticity. Low temperature resistance, can also be used in winter. It can be used for caulking and sealing of various cracks and holes, such as holes in air conditioners, exhaust fans, pipes, electrical switch boxes, wire outlets, etc., and can also be used for shock-proof packaging of fragile items.
