Low shellac content for elevated temp
Low levels of binder content (5-6% shellac) combined with specially selected splittings gives a rigid material, which can be punched or cut to shape. HR micanite is often used as an insulator in applications where the binder is decomposed at the operating temperature, which leaves only the mica insulation in place. Under such circumstances the mica must be firmly supported by sheathing or cladding. Heat resisting micanite can be supplied cut into rings for electromagnet insulation up to 60" in diameter.

The B9 family of products are high performance composite sealing/insulating materials designed to meet specific needs, primarily in the Oil and Gas distribution industries. B9109 combines the sealing properties of Neoprene with the strength and insulation properties of a fine weave SRBF laminate.
Conventional materials can cause problems due to either with being too soft to withstand the compressive forces of the mating surfaces or too hard to form a satisfactory seal. The thickness of the sealing rubber face(s) on Attwater B9 laminates is kept to a minimum (typically 0.4mm). This combined with the high compressive strength of the core eliminate the compression effects normally associated with softer materials. This makes the product capable of withstanding compressive loads in excess of 30,000 psi.
The product also acts as electrical insulation between the mating surfaces reducing electrolytic effects, which can lead to corrosion.
The Attwater Group also manufactures a complementary range of insulating bushes and washers to enable complete insulated flange joints to be assembled. Product Information: (Hover to view)

The Technolaque® SD Range is a breakthrough in static dissipation. Developed by the Attwater Group, originally for the A.T.E. market, it incorporates a static-dissipative thermosetting surface, which is less than 50 microns thick. This special surface can be integrally press bonded onto a range of sheet substrates including Phenolic paper and epoxy glass during the manufacturing process, providing permanent static dissipative properties on one or both surfaces.
As the Static-dissipative layer is not dependant upon additives bleeding to the surface, adhesive bonding of the manufactured components is possible. Also, the insulation properties of the core (below the static dissipative layer) are not affected permitting optimum insulation properties between conducting pins after suitable machining of the surface.
