SPECTER Monofilament Fibers are specially designed to minimize early-age cracking in concrete. Millions of high tensile, high modulus, filaments in every yard create an extremely dense, three-dimensional network in most cementitious applications. These fibers have the unique ability to reduce explosive spalling and damage in the event of a fire.

SPECTER™ Monofilament Fibers are manufactured from 100% virgin homopolymer polypropylene resins. SPECTER™ Fibers meet the requirements of ASTM C1116/C1116M “Standard Specification for Fiber Reinforced Concrete”, ASTM D7508/D7508M “Standard Specification for Polyolefin Chopped Strands for use in Concrete”, and the requirements of ICC ES AC32 Section 3.1.1 for plastic shrinkage reinforcement.

Features and Benefits

• Inhibits and controls the formation of intrinsic cracking in concrete
• Reduces plastic shrinkage cracking by an average of 75% at a specified dosage rate along with helping to prevent settlement cracking
• Reduces concrete permeability and increases the durability and service life of the concrete
• Provides three-dimensional reinforcement against micro-cracking
• Increases the impact and abrasion resistance of the concrete
