Twisted Bundle Polypropylene Fiber (TBPM B-40)
What Is Twisted Bundle PP Fiber (TBPM B-40)?
Twisted Bundle PP Fiber (TBPM B-40) is a high-performance synthetic macrofiber manufactured from virgin polypropylene. Its twisted-bundle structure improves fiber distribution within concrete, ensuring superior bonding and stress transfer compared to conventional fibers.
This advanced reinforcement material is engineered to reduce shrinkage cracking, improve tensile strength, and extend the overall lifespan of concrete structures. With easy integration and long-lasting resistance to harsh conditions, it’s an efficient alternative to traditional steel reinforcement.
