Raw Material-PU
PU is a product of 2-component Polyurethane. It adopts FIPFG (foamed-in-place foam gasket) technology which can foam on the
Workpiece directly. The finished product is a soft and elastic foamed gasket. This gasket is made from component A and component
B. Component A is mainly polybasic alcohol, Component B is a hardener-isocyanate. After mixing A and B according to a certain
Proportion and completely foaming, the mixture will become a soft foamed sealing strip. 





• Mixing time: Time for mixing component A and component B
• Reaction time: Time for the mixture to react( about15-60 seconds after mixing)
• Foam time: Time from reaction to finish (about 15-180 seconds)
• Dry time: Tiem for no viscosity on the suface, and no damage with touch under room temperature 25 ºC(about 2-20 minitues later)
