PVA Microfiber
High strength and high modulus PVA Microfiber for crack resistance of concrete
PVA Microfiber is a kind of high-strength and high-modulus engineering short-cut fiber, which can not only prevent the plastic cracking of concrete, but also effectively control the cracking of hardened concrete.
Product application
PVA Microfiber can be applied to concrete structures with high requirements for crack resistance and durability, especially for concrete projects with dual requirements for crack resistance in plastic stage and hardening stage and in harsh environmental conditions.
Technological advantage
■ Excellent dispersion
■ Ultra-high tensile strength, ultra-high elastic modulus
■ Control and prevent the cracking of fresh concrete and hardened concrete
■ Comprehensively improve the durability and mechanical properties of concrete
■ Improve the impact resistance, wear resistance, earthquake resistance and crushing resistance of concrete
■ Acid resistance, alkali resistance and corrosion resistance
■ Safe and easy to operate

Use method
■ PVA Microfiber can be added in the concrete mixing station, and the mixing time should be extended appropriately to make the fiber disperse evenly.
■ The range of PVA Microfiber content is 0.6-1.8kg/m³, and the recommended content is 1kg/m³.
Packaging mode
■ PVA Microfiber independent packaging, 1kg/ bag or specific design packaging according to the actual needs of customers.
■ PVA Microfiber products are kept away from heat and moisture.
Quality standard and certification
■ PVA Microfiber production conforms to ISO9001 quality management certification system.
■ Pioneer fiber series products are not included in the list of dangerous goods stipulated by 1272/2008/EC.
Matters needing attention
■ The plastic bag should not be fed directly, the package should be unpacked first, and then the fiber should be poured into the blender.
■ PVA Microfiber is completely physical in concrete and does not change the mix proportion of the original concrete.
