OPAN Felt

Oxidized polyacrylonitrile(PAN) fiber, also known as opan, opf, preox. OPAN fiber outperforms other technical fibers when it is directly exposed to flame, molten metal splash. OPAN fibers doesn't burn, melt in the flame. It has nearly zero shrink. Providing extremely dimensional stability and heat resistant to the products in the fire. Which greatly saves the equipment or human beings from the fire and heat risks. By blending with para-aramid, it can bring the best balance of thermal protection and mechanical strength.

Typical applications of our opan felts including
-Welding blanket
-NVH in railway & automotive
-Sleeves/garment for PPE
-Battery shell for EV

It is produced based on customer needs, ranging from 80gsm to 2500gsm.

Specific requirements on FR performance can be customized.
