Synthetic Laminates HD-270
Insulac-HD270 is constructed from a Chopped Strand Mat woven fabric with an Synthetic resin binder. The Synthetic resin system is not flame retardant, but has greater temprature resistance then epoxy/polymer grade laminates.
Normally used for electrical and electronic insulation where low moisture absorption, good chemical resistance, and very high physical strength is needed. Not recommended for wear application.
