无硫低硫柔性石墨纸

产品介绍Product showroom

该产品选用优质鳞片石墨，经化学处理，高温膨化，压制等系列工艺加工而成，具有耐高/低温、耐腐蚀、不老化、自润滑、可压缩性、回弹性等优良密封性能。它是生产各种石墨卷材、板材、带材、填料、垫片、增强板、气缸垫片的主要原料。

Expanded Graphite Sheet or Rolls are selected from thehigh purity natural flake graphite. They are made through thechemical treatment，expanding androlling through high-temperatureand mechanical procedure etc.This products has excellent sealingproperties such as high and low temperature resistance,corrosion-resistance, non aging,self lubrication, compressibility, resilience .it has been widelyused for making graphite sheet, rolls, strip, packing, gasket,reinforcing plate, cylinder gasket packing rings and various kindsof gaskets.
