Rockbond Polypropylene Fibres 6mm (RB PPF6)

Mortars, renders and concretes are more workable and cohesive when plastic, and flowing materials harden to produce products with greater flexural and tensile strengths. The fibres are also used to reduce or eliminate problems associated with drying out, shrinkage and cracking. The fibres are supplied in 1kg water dispersible packs, and have an indefinite shelf life. ROCKBOND POLYPROPYLENE FIBRES 6mm (RB PPF6) are strong, inert, monofilament polymer fibres specially designed to improve the plastic and hardened properties of cementitious materials.
