Polyurethane resin - Import export

Smart automation concepts enable us to meet the highest standards of manufacturing. Our products are manufactured in Germany and made in USA, in a cost-efficient manner. Benefit from our production expertise that has been continuously developed over many decades. Mechanical protection, reliable electrical insulation, moisture shielding and heat dissipation - with continuously optimized potting resins (polyurethanes, epoxies, etc.) and potting equipment, PRUFREX is a leader in the field of vacuum potting. When it comes to the safe protection of your electrical and electronic components, our state-of-the-art, automated manufacturing equipment meets all contemporary requirements. The use of specially adapted epoxy and polyurethane potting compounds ensures excellent potting characteristics and the best-possible impregnation of components and coils. These optimised potting compounds also contribute to optimal heat dissipation.

E57 are designed to fit directly to the terminals of your IGBT. Our range comprises standard as well as custom-tailored solutions which can be adapted to the specific geometrical and electrical requirements of your application environment. Connection is made through low-inductance copper bars which may vary in number, size and position according to your specifications. The UL:V0 plastic case houses compact and stable cylindrical windings, connected in parallel for maximum current strength and lowest possible selfinductance; it is filled with polyurethane resin, covered by a layer of UL94:V0 compliant resin protecting the winding package from humidity. Our highly reliable SecuMet™ film guarantees secure self-healing properties even under the most demanding operating conditions. Some of our E57 capacitors can be operated at ambient temperatures up to 105°C and are therefore suitable for usage in automotive and other critical applications
