High Temperature Fiber
High temperature fibers are specialty fibers that keep their strength and shape above 200°C. Not many materials do that. They resist heat, hold their dimensions, and don't corrode easily.
They're made through solution polycondensation and spinning. A typical example is polycrystalline mullite fiber. It can handle oxidizing atmospheres up to 1600°C. You'll find these fibers in silicon carbide furnaces, steel reheating furnaces, and other high-temperature equipment.
Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of high temperature fiber in China. If you're going to wholesale durable high temperature fiber made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Definition
High temperature fibers are specialty fibers that keep their strength and shape above 200°C. Not many materials do that. They resist heat, hold their dimensions, and don't corrode easily.
They're made through solution polycondensation and spinning. A typical example is polycrystalline mullite fiber. It can handle oxidizing atmospheres up to 1600°C. You'll find these fibers in silicon carbide furnaces, steel reheating furnaces, and other high-temperature equipment.
Working Principle
The fiber mat traps tiny pockets of still air. Air is a poor conductor, so this structure cuts down heat transfer by conduction and convection.
The light color and fibrous texture also affect radiant heat. The fiber reflects some radiant heat back toward the furnace center, and it re-radiates absorbed energy from its surface. This helps keep heat where it belongs – in the furnace chamber, not escaping through the shell.
Features
High melting and softening point
The fiber doesn't melt or deform at extreme temperatures. Mullite fiber survives at 1600°C while steel would be liquid.
Dimensional stability
It stays the same size when hot. You can build insulation linings that don't shrink or crack.
Durability
After long service above 200°C, the fiber still works. It doesn't degrade quickly. A ceramic fiber lining in a forging furnace can last five years or more.
Chemical resistance
It resists hydrolysis and many chemicals. That's why labs and aerospace shops use it.
Applications
Aerospace
Lightweight carbon composites handle extreme heat, cut weight, improve flight efficiency. Every kilo saved matters.
Industrial furnaces
Insulation fabrics save energy and keep furnace operation steady. A 3-inch fiber blanket can replace 9 inches of firebrick.
Power generation
Thermal insulation for nuclear plants, gas turbines, solar facilities. The high temperature fiber doesn't conduct heat and doesn't burn.
Fire protection
Fireproof materials protect people and equipment in hot work zones.
Electronics
Insulating fiber keeps heat from damaging sensitive components.
