Title:
超可撓性パイプ断熱体
Document Type and Number:
Japanese Patent JP2004514747
Kind Code:
A
Abstract:
The present invention relates to pipe insulation made from a polyolefin thermal insulation foam which is made by extruding, using a physical blowing agent, a foam composition comprising 77-99% by weight of a metallocene polyethylene, 5-18% by weight of a flame extinguisher, 3-8% by weight of a cell stabilizer and 0-5% by weight of other usual foam additives. The invention further relates to a method for preparing a physically foamed polyolefin thermal insulation foam and to the foam prepared therewith. The foam is very flexible and as a result the pipe insulation is particularly suitable for the thermal insulation of pipes for split air conditioning, district heating, solar energy exploitation and the process industry, even when it regards thin and/or twisting pipes. The pipe insulation can be recycled well.
