What is PP monofilament？
At Shandong Jianbang Chemical Fiber Co., Ltd., we explain PP monofilament in a very simple way: it is a single filament made from polypropylene. “PP” stands for polypropylene, which is a polyolefin polymer that can be melt-spun into fibers. “Monofilament” means one filament, not a bundle of many fine filaments. In general fiber processing, monofilaments […]
What Is Steel Fiber Reinforced Concrete Used For
Steel fiber reinforced concrete is used in places where concrete must do more than just carry weight. It is used where the slab or structure must also control cracks, handle repeated loads, resist impact, and keep working for a long time in hard service conditions. In simple words, steel fiber reinforced concrete is chosen when […]
Is polypropylene fiber better than polyester fiber?
When buyers ask whether polypropylene fiber is better than polyester fiber, the most useful answer is this: polypropylene fiber is usually the better all-round choice for standard concrete work, but polyester fiber can be better in some specific cases. Polypropylene is lighter, melts at a much lower temperature, and has a strong track record in […]
What Are the Different Types of Steel Fiber?
When people ask “What are the different types of steel fiber?”, they usually mean one of two things. They may want the standard classifications used in ASTM or EN standards. Or they may want the common market shapes they see in catalogs, such as hooked-end, crimped, straight, or twisted fibers. Both ways are correct. The […]
How to Choose a Macro PP Fiber Manufacturer?
Choosing a macro PP fiber manufacturer is not only about finding a low price. It is about finding a supplier whose fibers perform well in real concrete, meet the right standards, and stay consistent from batch to batch. That matters because macro polypropylene fiber is usually chosen for post-crack performance, toughness, and crack control, not […]
What Is the Difference Between GFRC and GRP?
The difference between GFRC and GRP starts with the matrix. GFRC means glass fiber-reinforced concrete. It is a cementitious material in which alkali-resistant glass fibers are embedded in a cement-based mix. ACI describes GFRC as a composite of alkali-resistant glass fibers embedded in a cementitious mixture, which can be paste, mortar, or concrete. ASTM C1666 […]
How Is Polypropylene Fiber Manufactured?
At Shandong Jianbang Chemical Fiber Co., Ltd., we manufacture polypropylene fiber in two linked stages. First, polypropylene resin is made from propene by polymerization. Then that resin is turned into fiber by melt processing, extrusion, cooling, drawing, and cutting or other downstream conversion steps. In simple words, we start with polymer, then we turn that […]
What Is the Difference Between FRP and FRC?
The difference between FRP and FRC is simple once you separate the letters. FRP means fiber-reinforced polymer. It is a composite material made from strong fibers inside a resin matrix. In concrete work, FRP usually appears as bars, tendons, sheets, strips, grids, or near-surface-mounted elements used to reinforce or strengthen concrete members. ACI explains that […]
What Is Polypropylene Fiber-Reinforced Concrete Used For?
Polypropylene fiber-reinforced concrete is used to control cracking, improve toughness, support post-crack behavior, and solve specific durability or fire-related problems in concrete. The exact use depends on the fiber type. Micro polypropylene fibers are usually used for early-age crack control. Macro polypropylene fibers are usually used where the concrete needs better performance after cracking. ACI […]
What Is Fibrillated Polypropylene?
Fibrillated polypropylene is a polypropylene fiber made in a slit-film form that opens into many small branching fibrils. In concrete, it usually means a micro synthetic fiber used to reduce early cracking and improve cohesion in the fresh mix. The National Precast Concrete Association explains that fibrillated fibers are a slit-film fiber where parts of […]
