Frequently Asked Questions

What are the primary applications for this ceramic fiber?

It is widely used as a friction material in manufacturing brake linings, brake drums (20-35% dosage), and brake discs (10-25% dosage) due to its high temperature resistance.

What is the softening point and heat stability of the fiber?

The softening point is above 1750°C, providing excellent thermal and chemical stability for high-performance industrial applications.

Does the composite fiber require additional organic fibers?

No, the CF-1035 and CF-1025 composite fibers are designed for cold-type production and do not require the addition of further organic fibers.

How should the ceramic fiber be stored?

It must be stored in a cool, dry place. Opened packs should be sealed as soon as possible to prevent moisture penetration.

What safety precautions are necessary during handling?

Industrial safety requires the use of local exhaust ventilation, explosion-proof equipment, and protective gear like chemical safety goggles to prevent irritation or static sparks.
