PU FOAM is a polyurethane polymer that reacts with moisture in the air causing it to expand to fill any shaped hole or cavity.T esealant/Whixpandable pu foam te expanding foam sealant PU Waterproof spray foam sealant he cured foam can be cut or shaped and painted as disired. It is used preferably for insulation and installation in the construction sector application can be filling cavities, break-throughs, cracks and gaps, sound and heat insulation bonding fixing mounting, etc.
History White expanding foam sealantexpansion foam sealant
The pioneering work on polyurethanes was conducted by Otto Bayer and his coworkers in 1937 in Germany. Polyurethane foams, including SPF upholstery (flexibile) foams, etc. were developed in the 1950's.

Other benefits include...
Closed cell SPF adds structural strength and glues a building together, thereby making it more resistant to racking events, such as hurricanes and high winds.
SPF reduces noise from outside by air sealing the building.
Closed-cell SPF can provide an added barrier against water intrusion.
SPF reduces drafts and increases comfort.
SPF helps maintain a comfortable, constant, temperature throughout the building, from room to room and floor to floor.
SPF assists in improving indoor air quality.
SPF reduces the infiltration of outside air pollutants and soil gases.
SPF can reduce moisture condensation and mold growth within the building walls and roof.
Excellent insulation efficiency of SPF can reduce heating and cooling usage dramatically.
HVAC equipment can be down-sized, thereby reducing construction costs.
SPF will not sag or settle.
SPF can eliminate the need for separate housewrap and vapor retarders.
SPF helps conserve energy, reducing CO2 emissions.
SPF contributes LEED credits for sustainable, green construction.
SPF can help reduce structural damage caused by high winds.
SPF contains no formaldehyde or ozone depleting substances.
