A single thread of polypropylene fibers consists of 22 compressed strings of microfiber. The fibers are mixed in with concrete in order to:
1. Prevent cracking
2. Protect against destructive effects of moisture
3. Increases strength of concrete surfaces (hollows & screed locations)
Our machines produce polypropylene fibers with diameters ranging between 0.4mm and 1.5mm and lengths between 20mm and 70mm.
