Kempt CR 840

Selenis Kempt CR 840 is a polymer that has been designed for high performance monofilament extrusion and fiber extrusion. This product’s extended life-span performance and durability makes it unique and the ideal choice to produce bristles for street sweepers.

Selenis Kempt CR 840 has a very high viscosity, delivering excellent melt strength when extruded. Its low creep characteristic ensures an extended life-span performance and guarantees durability. The hardness and rigidity of PET make it the perfect solution to sweep fragile road surfaces, such as cobblestone.  The inert polyester characteristics deliver a high resistance against biological and chemical attack.
