Solid insulation is an integral part of electrical and electronic components. It protects live parts by acting as an electrical insulator and by dissipating heat.
Polyurethanes have been used successfully in electrical engineering for over 35 years. Major fields of application now include the sheathing, fixing, embedding and encapsulation of electrical components with solid, bubble-free polyurethane systems.
As a leading global manufacturer of polyurethanes, Bayer MaterialScience AG satisfies the demands of the electrical engineering industry with its broad range of Baygal®/Baymidur® systems.
Characteristics of this class of polymer include:
minimal inherent heating during curing
cold workability down to 0 °C
quick curing using catalysts
curing with minimal stress and shrinkage
low pressure on encapsulated components due to shrinkage
good adhesion
good resistance to chemicals
high productivity
attractive cost/performance ratio
These advantages result in commercially attractive, technically superior solutions in the various sectors of electrical engineering. With their broad range of properties, polyurethane/casting resin formulations are firmly established in practical use.
