无硫/低硫柔性石墨卷材又称柔性石墨纸或柔性石墨板材，是用天然鳞片石墨经化学处理后，经过加热高温膨化形成石墨蠕虫，这种像蠕虫一样的石墨粉的密度约为0.003g/cc。然后经滚压形成柔性石墨卷材。膨胀石墨卷材不含粘结剂和填充物，因此纯度很高，具有良好的耐腐蚀性、耐放射性、 耐高/低温、良好的压缩回弹性、并具有自润滑性和不渗透性，适用于低压部位的密封。石墨卷材和金属薄板可以复合成多种形式的石墨复合板。

Sulfur free / lowsulfur flexible graphite sheet, also known as flexible graphitepaper or flexible graphite sheet, is made by the followprocess: First naturalflake graphite is deal with chemical treatment, then after heatingin high temperature it takes in forms of graphite worms, thedensity is about 0.003 g/cc . Thenafter rolling it became flexible graphite sheet. Expandablegraphite roll is without binder and filler, so the purity ishigh, with goodcorrosion resistance, radiation resistance, high / low temperatureresistance, good compressionresilience,andhave the self lubrication and non permeability, suitable for lowpressure parts of the sealling. Thegraphite sheet and the metal sheet can be combined to make variousforms of graphite composite plates.

 

性能特点： Performancecharacteristics
1.优异的耐热性和耐寒性。柔性石墨从-270度的超低温到3650度（在非氧化气体中）的高温，其物理性质几乎没有什么变化，在空气中也可以使用到450度左右；

Excellent heatresistance and cold resistance. Fromultra-low temperature of -270 degrees to 3650 degrees (in nonoxidizing gas) of high temperature, the physical properties hasalmost no change, in the air , it can also be used 450degrees.
2.优异的耐化学腐蚀性。柔性石墨除在王水、浓硝酸、浓硫酸、高温重铬酸盐、高锰酸钾、氯化铁等强氧化性介质中有腐蚀外，几乎对一切无机及有机介质都耐腐蚀；
   Excellentchemical resistance. Flexible graphite were corrosive inStrong oxidizing medium such as aqua regia,concentrated nitric acid and concentrated and high temperaturedichromate, Potassium Permanganate, ferric chloride,Corrosion resistantto almost all inorganic and organic media.

3.良好的自润滑性。柔性石墨同天然石墨一样，层间在外力作用下，容易产生滑动，因而具有润滑性，有较好的减磨性，摩擦系数小；

Good selflubrication. The same as natural graphite, the flexible graphite iseasy to slide under the action of external force, so it has theproperty of lubrication, good abrasion resistance and smallfriction coefficient;

4.回弹率高。当轴或轴套因制造、安装等因素存在偏离而出现径向圆跳动时，具有足够的浮动性能，即使石墨出现裂纹，也能很好密合，从而保证贴合紧密，防止泄漏。

High rebound rate.When the shaft or sleeve has a deviation and radial runout formanufacturing, installation problems, it has sufficient floatingperformance, even if the graphite cracks, it can close together,thus ensuring closeness and preventing leakage.
