Our PAC 251/ 2,1 dtex/ 6 mm F are specifically designed for binder mixtures and top layers of asphalt, for noise minimising coverings as well as for stone mastic asphalts. It can be used for the strengthening of road bitumen and polymer modified bitumen. The high UV resistance makes them ideal for outdoor applications with direct sunlight. Additionally, the fibres have a good heat and temperature resistance. The high toughness of the fibres provide a great resistance to crack propagation.
