What is Keratherm
KERATHERM® are highly flexible products comprising thermally conductive and electrically insulating single or multicomponent polymers filled with ceramic or heat conducting materials.
KERATHERM®, when mechanically reinforced by the incorporation of fiberglass or other materials, offers the user a versatile product that is superior in many aspects to conventional ceramic or mica discs.
KERATHERM® Standard film: Advantages and properties:
KERATHERM®- heat conducting films are characterized by their high thermal conductivity and their electrical insulation. In contrast to discs made of mica, aluminum or polyamide, KERATHERM® can be used without a heat conducting compound. Compared to the thermal compounds still frequently used, KERATHERM® does not dry out during continuous use hence retaining its good thermal conductivity properties over the years.
By using KERATHERM® products, mounting problems such as smearing and assembly errors can be avoided. Silicone-based KERATHERM® facilitates component mounting thanks to their selfadhesive properties. An optionally available single-sided adhesive coating also allows long term attachment, even up-side down.
KERATHERM® Films are mainly resistant to water, oils and their mixtures, organic solvents and chlorinated hydrocarbons, as well as the cleaning agents used to degrease and wash heat sinks, housings and printed circuit boards. These materials merely cause swelling of exposed edges of the heat-conducting film, whereat the degree of swelling depends on the contact period and the type of solvent applied.
After dry-out, the exposed edges return to their original state with no change in thermal or electrical properties. Due to the short contact times involved, KERATHERM® may be exposed to the conventional baths used in soldering processes.
The various KERATHERM® products are crosslinked and cured to elastomers during the manufacturing process. KERATHERM® products involve none of the substances specified on the VDA list of declarable substances. Our products do not require labeling in accordance with "ChemG/Gefahrstoff V" (Act for the Protection against Hazard Substances / Hazardous substance V). KERATHERM® products contain no asbestos, lead, mercury, chromium-6, cadmium and/or halogenated hydrocarbons.
Delivery form
Besides a large number of standard shapes (TO, TIP, DO or other power housing shapes), we can supply punch parts in customized shapes of any arbitrary size based on customer drawings (max. 400x400 mm). Roll goods can be supplied in widths of 15 mm up to 500 mm. All formats can also be ordered as bulk material. All flexible films - Softtherm® - can be delivered in thicknesses up to 1.0 mm or as roll goods up to 500 mm in width. Above a thickness of 1.5 mm, the Softtherm® films are supplied as sheets in sizes up to a maximum of 250 x 450 mm².
