SUNY SY-413 Polyether Defoamer
for Paper Making
Product Description
SUNY SY-413 is a type of polyether defoamer. This line of product is modifiers of the PP/PE block copolymer with polymer initiator; they have great capacity of foam breaking and inhibiting, which is different from normal polyether antifoam agent. With the capacity of eliminating small bubbles quickly and controlling foam everlasting, it rapidly removes tiny air bubbles among the fibers, clears float bubbles on the surface of the pulp, and also removes big bubbles on the surface of the water; It can totally eliminate the influence of the bubbles on the technology process, and then avoids the formation of pores and also reduces paper breaking. It prevents the overflow of the slurry pool which lead to the loss of fiber and wet end chemicals; papers can have better uniformity and greatly improved quality with its assistance.
