PP Chopped Strand Fiber 2D×5mm for Concrete Mortar & Thermal Insulation
Product Overview
Our PP Chopped Fiber 2D ×5mm is engineered from high-quality virgin polypropylene resin through precision cutting and surface treatment, delivering exceptional performance for construction, industrial, and composite applications. With a precise specification of 2 denier fineness and 5mm chopped length, this fiber ensures uniform dispersion, stable processing, and reliable reinforcement across diverse production scenarios.
Designed for superior crack control, the fiber effectively inhibits plastic shrinkage cracks, temperature-induced cracking, and settlement cracks in concrete and mortar systems. It significantly improves toughness, flexural strength, and impact resistance while enhancing structural integrity and service life.
