Polypropylene Fiber

Polypropylene cut fibre are fibres cut from continuously extruded polymer filaments called Tows Each individual fibre is cut to a precise length of 20mm 6mm - 20m.Precision cut Polypropylene fibre monofilament fibres are used to improve the "Green Strength" of refractory products. In addition to this reinforcement process, the fibre performs another important function. (On heating the refractory to start to dry it and later to start to "Fire" the refractory cement, the fibres initially shrink and as the temperature is increased, melt to form voids. The reduction in volume as the fibre shrinks and melts.) It allows trapped gases, especially water vapour to escape and prevent cracking of the refractoryrefractory cement.
