PPG Castable Polyurethane Prepolymer
l Application：It applies to make rods, caster wheel, rolls, sealing rings, screen plates and
other polyurethane wares.
l Characteristics：The wares have good abrasive resistance, water resistance, fungus
resistance and excellent mechanical property, regulating colors by adding
pigment.
l Operating Points：After the prepolymer vacuum degassing in 80～85℃, blend with melted MOCA, vacuum degassing, pouring, vulcanization
moulding. It suits for manual operating and mechanical casting.
l Storage：Store in cool and dry place，If you can’t use it up at a time, filling nitrogen gas and then sealing it. The
storage time of original packing is 6 month.
