Our products are mainly used as insulation in high-vacuum and inert atmosphere furnaces. This kind of high-vacuum is widely used for metal heat treatment, meticulous and ceramic sintering, different kinds of crystallization production, producing optical fiber, and sintering monocrystalline silicon for semiconductors, usually in a high-vacuum or inert atmosphere furnace. Since these furnaces work at extremely high temperatures, it is necessary to have insulation material that can withstand such high temperatures. Moreover, for energy conserving purposes, quality heat insulation material is the best choice. We pride ourselves in the ability to offer first class technical backup to our customer base, and over the years we have developed close technical partnerships with major fields including Aerospace, Semiconductor, Automotive, Specialist Castings, Metal Composites, Crystal Growing, Hard Metal Sintering, Graphitizing, and the Heat Treat Sectors.

  • Quartz/Fused Silica manufacturing: Melting/Sintering furnaces. 
  • Float glass industry: Insulating fasteners (part of liners). 
  • Tool manufacturing: Sintering and hot pressing. 
  • Universities and Government Research Centers: High temperature furnaces, fuel cells.
  • Aerospace: Hot isostatic process furnaces, heat treating, sintering, brazing furnaces, autoclaves. 
  • Semi conductors: Silicon pullers, gallium arsenate producers, furnaces. 
  • Metalizing (metal heat treating): Heat treating furnaces, sintering, brazing furnaces. 
  • Fibers manufacturing: Carbonizing furnaces, graphitizing furnaces - induction or resistance tube furnaces. 
  • Ceramics: Pyrolytic depositing furnaces, CVD furnaces, CVR furnaces.
