Schupp Industriekeramik GmbH

UltraVac insulation materials offer very precise dimensions, surface quality and homogeneity in particular at complex part designs. This way, we implement individual and application-specific unique vacuum-formed 3-dimensional insulation shapes or small series, made of non-classified polycrystalline mullite/alumina wool (PCW). These parts are being used as cylinders, rings or vestibule blocks in CVD-, hydrogen-, oxygen or diffusion-furnaces up to 1.600 °C (2.912 °F) operation temperature.

The structure of the vacuum-formed insulation shapes remains stable even at high temperature. Thanks to the very good thermal shock behaviour, UltraVac is suitable for use in high-temperature furnaces with rapid temperature gradients.

Your benefits with UltraVac:

• Complex design possible
• Very good thermal shock behaviour
• Stable structure at high temperatures
• Longer lifetime compared to commonly used vacuum formed insulation parts

We combine intermetallic high purity heating elements made of molybdenum disilicide (MoSi₂) and vacuum-formed insulation made of polycrystalline mullite/alumina wool (PCW) according to your demand. Our heating systems allow process temperatures even up to 1.450 °C (2.642 °F), strongly depending on application and geometry, and ensure uniform heat distribution and high energy efficiency. MolyTec is fully compatible with all technically comparable heating systems.

Your benefits with MolyTec:

• Quick and simple installation and exchange
• Long service life compared to commonly used heating systems with e.g. wire
• Reduction of the process time in terms of higher process temperature compared to wire
• High surface loading: 15.5 W/cm² at 1.400 °C (2.552 °F)
• Homogeneous temperature distribution

MolyCom®-Hyper 1800 are electric heating elements made of the high purity intermetallic compound molybdenum disilicide (MoSi₂) with ceramic additives. Thanks to their unique properties the MoSi₂ elements enable a higher surface loading compared to commonly used electric heating like e.g. with wire. Thus, they can be used for operation temperatures higher than 1.350 °C (2.462 °F).

MolyCom®-Hyper 1800 heating elements can be combined with vacuum-formed insulation tubes made of polycrystalline mullite/alumina wool (PCW) to electric heating systems for CVD-, hydrogen-, oxygen or diffusion-furnaces. The elements are supplied, also in complex geometries like 360° panorama heating elements.

Your benefits with MolyCom®-Hyper 1800:

• Higher surface loading compared to alternative heating solutions
• Longer lifetime of the heating elements
• Available as ready for installation heating system with vacuum-formed insulation tube up to 1.450 °C (2.642 °F) operation temperature, called MolyTec

ITM-Fibermax® is the flexible version of the thermal insulation made of polycrystalline mullite/alumina wool (PCW). The material is a very good substitution for ceramic-fibre materials (RCF). It is particularly suitable for temperatures above 1.250 °C and applications that require a very high chemical resistance. The needled blanket can be used as external insulation in CVD-, hydrogen-, oxygen or diffusion-furnace.  ITM-Fibermax® is available in thicknesses of 12.5mm and 25mm.

Your benefits with ITM-Fibermax®:

• Shot-free and free of ceramic-fibre (RCF-free)
• Long service life due to low shrinkage
• Perfect thermal stability and thermal shock resistance
• Low heat conductivity
