Permali®/Insulam®/Laminated Beechwood Technical Information
Laminated
Beechwood Technical Information Permali® or Insulam® is an insulating
material used in applications which require high tensile and compressive
strength (see table below). In addition, due to its exceptional resistance
to moisture, it serves as a suitable insulator where the support (flare
lines & dummy legs) is exposed to harsh environment elements. Permali®
or Insulam® is a phenolic laminated (densified, impregnated wood)
product made from carefully selected thin beechwood veneers. These
wood layers are impregnated under vacuum conditions with a special
synthetic resin and then densified through the application of heat
and pressure. The result is a homogenous material that combines the
great strength and toughness of wood fibers with the excellent stability
and dielectric properties of the most advanced thermosetting. The
phenolic laminated block material is furnished with cross-directional
fibers as shown in Figure 10 below.

NOTE: Cross laminated.
For components in compression or for parts stressed in more than one direction.
Sizes to suit most applications.
