High-performance crack control and toughness for concrete, shotcrete, and precast.
Twisted Bundle PP Fiber (also called “bundled PP macro fiber”) is produced by precision drawing and surface treatment so that each bundle separates rapidly during mixing and forms a dense 3D reinforcement network. Compared with plain monofilament, the twisted bundle delivers faster opening, stronger mechanical anchorage and higher efficiency at the same dosage. It is chemically inert, non-corrosive, lightweight, and causes zero wear to mixers and pumps.
ECOCRETE™ Twisted Bundle PP Fiber is engineered from premium polypropylene and processed to open quickly in mixing, dispersing into thousands of micro-filaments that bridge micro-cracks and toughen the matrix. It improves crack control, anti-seepage, impact resistance and durability across floors, roads, tunnels and water structures.

Each shipment includes packing list and QC documents to speed up customs clearance.
We cooperate with reliable carriers and forwarders to offer port-to-port or door solutions. Consolidation, pallet optimization and documentation support help shorten lead time and reduce landed costs.
A: It starts as a twisted bundle that opens faster and creates a stronger 3D network, giving better crack control and toughness at equal dosages—especially in shotcrete and heavy-duty slabs.
A: In many crack-control applications it can partially replace secondary steel mesh. For structural load-bearing design, follow the engineer’s specification.
A: Slightly. Adjust water or superplasticizer to maintain target slump. Proper mixing prevents balling.
A: Yes. Twisted Bundle PP Fiber is non-corrosive and chemically resistant, ideal for marine and chemical facilities.
A: Yes. Lengths, inner bag weights and pallet plans can be customized. Project-specific tests and reports are available.
Every batch is traceable. We provide COA, SDS, TDS, factory ISO9001 and project-specific third-party test reports upon request. Original stamped copies and bilingual versions are available.
