THERMAL INSULATION

CALOSTAT® as super insulation material and AEROSIL® as a raw material for insulation materials, e.g. like VIP and HTI are high performance materials within the market segment thermal insulation, enabling fire protection and super insulation over a wide temperature range.

FUMED SILICA 

AEROSIL® in VIP

Application

Technical Advantages

AEROSIL is used as the raw material for the cores of fumed silica based Vacuum Insulation Panels (VIP).
Core materials for VIP require a completely open-porous structure to allow evacuation and must have a sufficiently high compressive strength to withstand the mechanical pressure load. Due to its micro porous structure AEROSIL prevents convection in case of a slight pressure increase within the VIP and even in case of vacuum failure AEROSIL provides good thermal insulation. AEROSIL is able to absorb humidity which gets into the VIP though the sealing film by water permeation. The absorption is indispensable to keep the thermal conductivity very low. Otherwise getters have to be added. AEROSIL is the only core material which can guarantee a long life for VIP, up to 30 years, and is the most common core material for high performance VIP.

SYNTHETIC AMORPHOUS SILICA BASED SUPER INSULATION BOARD

CALOSTAT®

Application

Technical Advantages

Mineral board for thermal insulation with highest performance and fire protection.
A mineral material with unique properties and a thermal conductivity of only 0.019 W / (m ∙ K). In addition to both the excellent thermal insulation under summer and winter conditions, and its non-flammability, CALOSTAT is characterized by non-combustability, vapor diffusion openness and core hydrophobization. As a result, completely new and more efficient insulation systems are possible, resulting from the combination of material properties of CALOSTAT.
