Thermoset Plastic Laminates are
uniformly dense and structurally strong material that will not soften
appreciably under the reapplication of heat. It is an extremely durable
plastic that is lightweight and moisture resistant. Industrial laminates
are thermoset resin impregnated reinforcing materials (paper, cotton
fabric, glass fabric, etc.) that are cured under heat and pressure to form
solid shapes having high mechanical and electrical insulating properties.
Laminates are available in sheet, rod, tube, and angle. Since laminates
are comprised of a combination of materials, they are also referred to as
composites.

Linen L/LE Cotton Fabric Reinforced Phenolic - natural
(light tan to brown)
Technical Data Sheet
Chemical Resistance Chart L, LE
Prices and Sizes
This grade is composed of a continuous cotton woven cloth impregnated with
a phenolic resin binder. This grade contains a fine weave linen and, like
the canvas phenolic, is known for it's mechanical properties. The finer
weave allows for machining more intricate details than Canvas, like gear
teeth. This grade is not recommended for primary insulation.
