Paper Making Machine Parts - UHMWPE Vacuum Suction Box Cover
Huatao suction box covers and blades are made of UHMW-PE material. UHMW-PE dewatering element is known for its high dry-film lubricant content. This produces an extremely smooth surface, most importantly resulting in a low friction coefficient a low level of adhesion. No adhesion Excellent chemical resistance. For machines with speeds up to 800 m/min.
Huatao dewatering elements in ultra high molecular weight polyethylene set themselves apart by the special sinter press procedure over a long period used to produce them, as well as an extremely high molecular weight plus their extra additive that is specifically tailored to paper machines. All these benefits ensure what is an outstanding service life for plastic coupled with a low coefficient of friction.
