CHICAGO — Albany International High Performance Materials' Pyropel nonwoven insulation improves cooling and bubble stability in Egan's WesJet air rings.
Egan, a Somerville, N.J., division of Davis-Standard Corp., uses Pyropel, a lightweight polyimide fiberboard, to seal the gap between the WesJet die and air ring, preventing heat transfer.
Albany of Mansfield, Mass., featured Pyropel samples at NPE 1997 in Chicago.
Pyropel replaced a white mineral hardboard insulation that tended to crack and fall apart. Egan buys and cuts the Pyropel sheets. The material withstands compression of the air ring but is resilient enough to seal the gap. It withstands temperatures as high as 600° F.
