ABSTRACT:
Methods and apparatus for producing high quality closed cell foams for use in applications such as coatings, sealant beads, seam filling and gaskets. An in-line single pass static mixing device containing a very large number of individual mixing elements is used to homogeneously disperse a gas throughout a highly viscous liquid polymeric material such as a plastisol, silicone, butyl or urethane based material.
