Bedford Materials Co., Inc. (BMI), is the world leader in
the development of electrical insulating materials. Formed in 1995
after purchasing the flexible insulation products plant from Westinghouse
Electric Corporation – the original inventor of electrical products
– BMI took over the then world-renowned provider of electrical
insulation and quickly maintained the leadership role in developing
and transferring world-class, state-of-the-art manufacturing products
to government and commercial industry.
BMI is recognized as a quality supplier, achieving both ISO
9002 and QS 9000 certification, in addition to receiving numerous
customer quality awards.
BMI's product line is the most extensive in industry, consisting
primarily of coated papers, flexible coated fabrics, flexible composites
and prepegs for diamond pattern. Products molded from our prepegs
for advanced composites.
A wide variety of substrates, including kraft paper, glass,
cotton, Kevlar™ cloths, polyester film, Nomex™ paper, and
nonwoven mats and felts are coated with thermosetting resins. These
resins can either be B - staged or fully cured and range from oleoresinous
and polyester, to epoxy and silicone. They are used in a variety of
applications in the manufacture of motors and transformers.
Our flexible composites, or laminates, are combinations of
two or more flexible materials that take advantage of the unique properties
of those materials. Most often, one of the components is polyester
film laminated to either a nonwoven mat, rag paper, Nomex™ paper,
or metal foil. Applications include slot, phase and wedge liners in
motors, or ground and layer insulation in transformers.
BMI's coated papers are either fully coated or pattern coated.
We are known worldwide for our diamond-pattern coated kraft paper,
used primarily as the major insulation in oil-filled distribution
transformers.
Our advanced composites are used in place of metal in many
applications, including aircraft and armor. BMI coats substrates,
such as glass, Kevlar™, and Spectra™ with a variety of resins,
including phenolic, epoxy, and polyester. A large percentage of new
military helmets have been molded with material developed and coated
by BMI.
