The secret of Kevlar felt roller sleeves

Kevlar felt roller sleeves Density:430g/m²·mm, Thickness: 8mm-12mm, Kevlar roller Dimension(L*W*H): Customized Size, Kevlar felt roller Load Capacity: Below 2000T UST Extruder Aluminum Profiles.

When the aluminum profile is extruded through the die, the temperature can reach 5500℃, and ordinary materials cannot withstand such high temperatures for a long time. Kevlar fiber is a kind of high temperature resistant material, its maximum temperature resistance can reach 480℃.
Due to the low density of Kevlar fiber, the tightness of the Kevlar tube and the para-aramid fiber below is adopted. The needle-punched temperature-resistant felt tube of Kevlar fiber and para-aramid fiber layer is most suitable for the aluminum extruder. A feed inlet and sliding introduction.
Because Kevlar is a metal fiber, its strength is very high (20 times that of steel). High-density Kevlar will cause difficulties in the production process. For example, broken needles are the biggest technical problem. After years of practice and research, we have mastered the most reasonable production process and the best balance point of Kevlar layer thickness and density.
The strong and dense Kevlar layer can ensure a continuous high-temperature environment of 480°C and can withstand the abrasion of sharp-shaped aluminum. Therefore, continuous wear will wear a layer on the surface of the Kevlar block. Once the Kevlar fiber layer is wrapped, the key to the service life of the Kevlar drum is the density of the Kevlar surface, not its thickness. The service life of the nylon fiber bottom is more than 15 days. The warranty period is one year

In addition to making Kevlar roller covers, it can also make Needle felt rollers, kevlar endless seamless belts, endless timing belts, pads, pegs, spacer sleeves, and a lot more customer-specific Needle felt items
