Raku-Raku®超高温石墨填料
此填料是由最新研发的超高温石墨材料根据尺寸要求模压成环。它不但具有普通石墨填料的所有特性，而且有个关键特性：在氧化状态下最高温度可达到650℃，而且在持续高温下的稳定性是普通石墨填料无法达到的。因此解决了在超高温领域的密封要求。
Raku-Raku®Ultra-high Temperature Graphite Mould Packing
The packing is molded into ring of newly developed ultra-high temperature graphite materials according to size requirements. Not only does it have all the properties of ordinary graphite packing, but it also has a key characteristic:maximum temperature can reach 650°C under oxidation,furthermore, the stability at constant high temperatures is beyond the reach of ordinary graphite packing.The sealing requirement in the field of super high temperature is solved.
