What is Ceramic Fiber Bulk?

Ceramic fiber bulk is the raw fiber cotton produced through specialized melting and fiberization processes. It is the fundamental raw material for manufacturing various ceramic fiber products (such as blankets, boards, papers, and modules).
 
We offer bulk fibers with various compositions like AES, PCW, and RCF, which possess excellent thermal insulation, low thermal conductivity, and good chemical stability.

Advantages and Value of Bulk Technology

AES Bulk · Biodegradable Fiber Technology

Uses advanced calcium-magnesium-silicate chemistry to provide safer, greener, and sustainable solutions.
AES bulk is produced using calcium-magnesium-silicate chemistry, meeting strict environmental and occupational health requirements. It is a safer and more eco-friendly high-temperature insulation solution.
  • Biodegradable (AES fiber)
  • Eco-friendly
  • Low shot content
  • Excellent processability
  • Max temperature up to 1260°C
  • Stable chemical properties
