SPECTER® HP SYNTHETIC MICRO FIBER is a “Best In Class” new generation of polypropylene microfiber for reinforcement of concrete. Fabpro’s unique technology combines ultra thin diameter with ultra high strength, resulting in the highest level of plastic shrinkage crack prevention available. Hundreds of millions of high tensile, high modulus filaments per yard of Specter(R) HP create an extremely dense, three-dimensional network in any cementiscious application. Specter(R) HP’s superior ability to reduce early age cracking is accomplished at an engineered dosage rate of only1/2 lb. / yd3. Independent test results have consistently confirmed: 1/2 lb. of Specter HP consistently produces superior PSCR results as compared with any other fiber at a typical 1.0 lb. / yd3 dosage rate

– providing better performance at a significantly reduced in-place cost.

 

Specter® HP Fibers are manufactured from 100% virgin homopolymer polypropylene resins,

and meet the requirements of ASTM C1116/C1116M “Standard Specification for Fiber-Reinforced Concrete” and the requirements of ICC ES AC32 Sections 3.1.1.
