Fumed Silica VIPs For Refrigerator
Core + film covering
The core of the insulation panel consists of pressed powder, whose main component is micro-porous silica. Other components include opacifiers to minimise infrared radiation, and cellulose fibres to improve mechanical stability.
Vacuum insulation has a long service life
The panel core is non-flammable and has been assigned fire class A1
Vacuum insulation panels (VIP) do need significantly less space than conventional insulation (such as mineral wool) material. Our panels only need one fifth of the thickness of conventional insulating materials to achieve comparable insulation values. In both cases the core material is wrapped in a metal coated foil and the air inside was evacuated. Of course the goal of both applications is different. The evacuation process is reducing significantly the heat conductivity of the panel.
The core material of high quality vacuum insulation panels mainly consists of silica (preferably fumed silica). Cheaper VIPs contain glass fibre as core material. Unfortunately these VIPs do have tremendous ecological and technical disadvantages
With thermal conductivity 4.5mW/mk, it would take approximately 175mm of traditional insulation wall thickness to equal the Vacuum Insulation Panel`s 25mm thermal efficiency.

The research report also shows that the availability of some of the more advanced pumps will also promote the demand of the US pump market, and the market demand for products that are tending to be eliminated will decline. The manufacturing and processing industry will continue to maintain its position as the largest user of pump products, and the demand for pumps will grow at an average level. In the next few years, centrifugal pumps will continue to be the mainstream product of U.S. pump designs. This is mainly due to the advantages of centrifugal pumps with a wide range of pressure and load handling capabilities, and at the same time relatively low maintenance costs.
According to the latest research report of Freedonia Consulting Company in the United States, supported by promising prospects for many pump-use industries, the demand for the US pump market by 2010 is expected to grow at an average annual rate of 2.7%. By 2010, the market demand will reach US$8.5 billion. The industries that have contributed the most to this include chemicals, petroleum refining and pulp and paper industries.
