Heat-conductive adhesives - Import export

Whether an individual circuit board or full-scale, demanding device assembly – PRUFREX will manufacture your products to your individual specifications and quality guidelines. Dispensing technologies allow us to adjust your components to additional requirements. Our range of services covers all dispensed materials, from adhesives through heat-conducting pastes to silicones. Depending on your project requirements, we offer you the most efficient routes to implementation – from manual production to CNC cells.

Examples of materials for dosing: 1- and 2-component epoxy, UV / light-curing / thermosetting adhesives, highly filled materials, anaerobic adhesives, shear-sensitive adhesives, heat-conducting paste, sealants, flavourings, silver conductive paste, flux, perfume, isopropanol, industrial oils, silicone, alcohol, grease, paint and ink, MEK, braze paste, PU, acetone, petrol and many others. The preeflow® eco-DUO is a rotating, absolutely pressure-tight displacement system consisting of a self-sealing rotor and stator. The controlled rotary movement of the rotor generates the flow by displacing the medium in the stator. Pumping without changing the medium is guaranteed. As the material can also be conveyed backwards, preeflow® guarantees a clean, controlled material or medium tear-off without dripping. Application: - point dosing, with highest volumetric accuracy - bead application with application speed adjustable to the web speed - Potting technology

High-performance heat sinks from Seifert electronic are exclusively designed for forced cooling applications. The powerful heat sinks from the Vario and DKL series impress with their large cooling surfaces. Utilizing a finned construction, rib spacing can be manufactured that is not achievable with conventional extruded profiles. Thanks to maximized surface area with the same weight, a high-performance heat sink delivers above-average cooling performance per unit volume. We have patented our proprietary compression geometry at Seifert electronic. In this process, individual fins are precisely cold-pressed into a heat sink without the use of adhesives. Heat conduction in the finned heat sinks occurs directly from the base to the fins, without any thermal transition as seen with pressed-in ribs into a solid base. Custom mounting holes can be incorporated into the pressed, surface-milled base.

By mounting an axial fan, the effectiveness of the new Kühligel® can be increased considerably. Fanless solutions require a lot of space. They are heavy and expensive. For cooling with active coolers by SEPA EUROPE however, the new Kühligels are not only small and light but also extremely inexpensive. Thanks to intensive development work, SEPA EUROPE was able to construct a heat sink that enables fan mounting without extensive reworking using conventional screws. The choice of the suitable fan (size, sleeve or ball bearings, 5, 12, or 24 VDC, tacho, connector) enables the best possible combination that is required for the application in question. The fans used have a MTBF of up to 350000h (40°C) and thus meet the highest requirements. Thanks to its light weight, the Kühligel® can usually be mounted using double-sided adhesive heat conduction pads (TCTxx) or thermally conductive two-component adhesive (Hernon 746) which are both available from the SEPA EUROPE product range.

Thermally conductive tapes offer high performance heat dissipation; vital requirements for designing electronic devices where demand is for slimmer and more powerful features. Thermally conductive tapes offer a clean alternative to pastes and liquid adhesives and can be die-cut to bespoke designs, providing efficiency of application and reducing assembly times. Double coated and transfer thermally conductive tapes are available in a variety of thicknesses
