It is a structural macro synthetic fiber reinforcement composed of twisted (twist) monofilament fiber bundles and manufactured from 100% pure copolymer/polypropylene material. Polytwist ® PTB36 is produced with an effective fiber size to provide maximum efficiency in topping concrete applications thinner than 15 cm. In addition, thanks to its twisted structure and the fibrillated fibers it contains, it provides long-term maximum durability without corrosion risk and helps reduce plastic shrinkage cracks. Polytwist PTB36 eliminates the need for traditional methods such as welded wire mesh reinforcement and steel wire. It is also corrosion-resistant, antimagnetic, and 100% resistant to alkali and acids. Thanks to its soft structure, it embeds better after finishing and does not appear on the surface. It reduces workmanship and the number of finishing operations. Thanks to its fibrillated content, it also eliminates the need for additional micro fiber usage. With its blended structure, you obtain both main reinforcement and micro reinforcement that prevents surface cracks in a single product.
