Polypropylene (PP) Fiber

Star polypropylene (PP) fibres are hydrophobic, which do not absorb the water, and are non-corrosive. Moreover, the polypropylene fibres have excellent resistance against alkali, chemicals and chloride and have low heat conductivity. By these characteristics polypropylene fibres have therefore no significant effect on the water demand of the fresh concrete. They do not intervene the hydration of cement and hence do not influence unfavorably the effects of all constituents in the concrete mixture.Polypropylene is the lightest synthetic polymer. Hence the count of fibre for a given weight is maximum in case of polypropylene. It is 52% lighter than polyester and 26% lighter than nylon and acrylic. Hence polypropylene fibres are ideal for reinforcement. Star PP fibres are treated with special chemicals for better dispersion and bonding of the fibre with the cementitious matter. Star PP fibers are compatible with all concrete admixtures and performance enhancing chemicals. Star PP fibres are easy to use and they disperse easily.
