This felt cover has Nomex® Fibers with excellent flame resistance and thermal protection. Fibers do not melt or drip, and its instantaneous temperature resistance is 280°C . Nomex felt rollers are capable of withstanding operating temperatures of up to 280 C , Nomex provides a stable and high temperature product well suited to conveying extrusions as they begin to dissipate heat

When aluminum profile comes out of the extruder,the temperature is about 550℃ and not many materials can stand such high temperature for long time.PBO fiber is the kind of material that can resist high temperature up to 600℃,The PBO roller composed of PBO is ideal to use at extrusion initial area and beginning of the run-out table.It is the density of the PBO layer enables the rollers to work continuously under temperature 600℃,and at the same time to stand the abrasion from different shapes of the profile.Super high temp. resistance felt roller,Suitable for use before fly cut.Effectively improve the scratch mark made by the graphite. (Ultra-high Temp. Zone)

This felt cover has Zylon Fibers (PBO Fibers), it is a super fiber with extreme heat and flame resistance. It is creep resistant and the instantaneous temperature resistance is 600°C . PBO rollers are capable of withstanding operating temperatures of up to 600 C . PBO’s high strength provides superior performance for high temperature extrusion applications.

Kevlar felt rollers are capable of withstanding operating temperatures of up to 480˚ C /. High strength and superior abrasion resistance make this a preferred product for many extrusion conveying tables.This felt cover has Kevlar fibers with resistance to chemicals and extreme temperatures. It is flame resistant, self-extinguishing, and its instantaneous temperature resistance is 480 °C
