    • 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.
    • 本发明涉及由聚烯烃绝热泡沫制成的管道绝缘体,其通过使用物理发泡剂挤出泡沫组合物制成,泡沫组合物包含77-99重量%的茂金属聚乙烯,5-18重量%的火焰 灭火器,3-8重量%的电池稳定剂和0-5重量%的其它通常的泡沫添加剂。 本发明还涉及一种用于制备物理发泡聚烯烃保温泡沫的方法及其制备的泡沫。 泡沫是非常灵活的,因此管道绝缘特别适用于分体式空调,区域供热,太阳能开采和工艺工业管道的隔热,即使是薄型和/或扭转管道。 管道绝缘可以循环利用。

    • The invention relates to a thermally insulated wall, comprising a layer (2) of insulating material connecting onto the wall and an air-excluding sealing layer (3) arranged on the outside of the layer of insulating material, wherein the layer of insulating material is divided into compartments by air-excluding separating surfaces (12, 13, 14) extending substantially transversely of the insulated surface. The available volume of oxygen is hereby reduced so that a possible exothermic reaction cannot spread, or hardly so. The danger of punking is hereby greatly reduced.
    • 本发明涉及一种隔热壁,其包括连接到壁上的绝缘材料层(2)和布置在绝缘材料层外侧的排气密封层(3),其中绝缘材料层为 通过基本上横向于绝缘表面延伸的不包括分离表面(12,13,14)的空气分成隔室。 因此可以减少可用的氧气体积,使得可能的放热反应不能扩散,或几乎不能扩散。 冲击的危险因此大大降低。
