【600℃ PBOroller】 | technical parameter |
| Product Name：600℃PBOroller（Ultra high temperature roller） | colour：Surface coffee / Brown + bottom yellow | model：roller-PKR | component：Surface PBO fiber + bottom Kevlar fiber | Product performance：
1- PBO is a kind of metal fiber with very high strength (20 times that of steel). Too high density of PBO will bring technical problems such as needle breakage to production, so its manufacturing process is very complex. After years of research and continuous practice, combined with reasonable production technology, the thickness and density of PBO layer are effectively balanced, so as to ensure the reduction of production costs and the improvement of product quality to a greater extent;
2- It can provide special resin hardening process to improve the wear resistance of products, so as to prolong their service life. | Product use：
It is mainly used in the ultra-high temperature area before the interruption of the extruder outlet (within 10 meters from the extrusion outlet) in the aluminum plant, and can also be used for sliding, which can effectively improve the scratches and black spots caused by the use of traditional wood strips and graphite products. Common specifications：3+7 | thickness（mm）:2+8/3+ 7/4+6，2/3/4为PBO层，8/7/6为KEVLAR层； | internal diameter：￠41/43/44/45/49；￠50/51；￠60/61/62/63；￠76/77；￠80/81/82；￠90/95；￠100/101/102；￠114/115；￠120/127 | length（mm）:Production according to customer requirements |

Detailed description
In the forming process of aluminum alloy, the early wood and graphite have been replaced by heat-resistant felt. The heat-resistant felt is both high temperature resistant and wear-resistant, and its texture is soft and pollution-free. It solves the problem that the traditional graphite cannot prevent the scratch of aluminum profiles and the black marks left by post-treatment. In recent years, it has been increasingly adopted by many manufacturers. The high temperature felt roller of our company is made of American DuPont fiber needled. Heat resistant felt can be made into various shapes, such as felt roller, felt sleeve, felt gasket, seamless filter felt tube, etc. it can also be hardened with special high-temperature resin. The service life of the hardened felt is nearly twice that of the original one
