Polypropylene Fiber

PP Fiber, also known as polypropylene fiber, anti-cracking fiber, and concrete reinforcement fiber,is a synthetic microfiber made from 100% virgin Polypropylene material. These fibers are incredibly fine, consisting of single filaments.When added to concrete, PP Fiber acts as a reinforcement, improving its overall strength, ductility, and crack resistance. It helps control the formation and propagation of cracks, enhancing the durability and lifespan of concrete structures.
