FiberForce 350 is an ultra-fine denier fibrillated micro fiber manufactured from 100% virgin homopolymer polypropylene resins. FiberForce 350 is primarily used as shrinkage and temperature reinforcement in concrete.
FiberForce 350 is packed in pre-weighed degradable bags. FiberForce 350 can be preloaded in empty ready-mix drums or added anytime during or after concrete is batched. Mix for 5 minutes at full charging speed (75-100 revolutions) to ensure complete dispersion of fibers.
