Syntactic foam invar
WebSyntactic Expanding Films. Toray's expanding foams are used in closed mold applications to generate internal pressure, as the hollow microspheres inside expand with the application of heat during the curing process. They feature good high … WebSyntactic composites are materials created by mixing a solid with minute spheres of glass, ceramic, or polymer. When the spheres are hollow, the materials are considered syntactic foams. Derived from the Greek word syntaktikos, the word syntactic means to arrange together. The key ingredient of syntactic foam is the microsphere, or microballoon.
