HIGH PRESSURE LAMINATES
Click For Price Pages: Sheet
( PAPER - CANVAS - LINEN - G-10/FR-4 )
These materials are used in applications where you may require:
-
Very High Electrical Properties
-
Very Stiff and Rigid Material
-
Machinable Material with High Mechanical Properties
Paper Base (X, XX, XXX, XP) -
Composed of a paper base impregnated with a phenolic resin binder. It has excellent electrical properties with fair mechanical strength. Outstanding for use as template material or backup material.
Canvas Base ( C, CE ) -
This grade is composed of a continuous cotton woven cloth impregnated with a phenolic resin binder. This grade contains a medium weave canvas and is known primarily for it's mechanical properties. Not recommended for primary insulation.
Linen Base ( L, LE ) -
This grade is composed of a continuous cotton woven cloth impregnated with a phenolic resin binder. 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 machining details than Canvas, like small gear teeth.
G-10 / FR4 -
The most versatile all-around laminate, this grade is comprised of a continuous glass woven fabric base impregnated with an epoxy resin binder. It has extremely high mechanical strength, good dielectric loss properties, both wet and dry. Extremely abrasive while machining, diamond tooling is recommended.
