Graphite GR8888

Composition

GR8888 is a special graphite packing with high carbon content. its yarns are very flexible and elastic, completely insensitive to the thermal cycles. All the threads are impregnated with a special graphite mixture enriched with a corrosion inhibitor. The GR8888 graphite packing resists very well to the high temperatures, without losing weight and volume, while maintaining high mechanical properties.

  • Never use the product to the maximum temperature and pressure associated. Consult the manufacturer for further information

  • The peak temperature can be sustained for short exposures

  • With weakly oxidizing agents and hot air the temperature must be limited to 450 ° C

  • With steam and non-oxidizing fluids the temperature must be limited to 650 ° C

  • Graphite and carbon cannot be used with oxidizing fluids
