Special Synthetic Fiber for UHPC:

Our UHPC-specific synthetic fibers are modified polypropylene fibers. This modification overcomes the traditional process where physical indentations reduce fiber tensile strength (as the fiber diameter is only 0.2 mm, physical indentations only reduce the fiber’s tensile strength). Through modification, not only is the original tensile strength retained, but the fiber also exhibits improved adhesion to concrete, increasing the toughness and flexural performance of high-performance concrete.

Special concrete reinforcing Fibers for industrial floors：

One of our best-selling products is the industrial flooring-specific concrete reinforcement fiber. Its unique structural design forms a three-dimensional support system within the concrete, enhancing the compressive and fatigue resistance of industrial concrete floors. It replaces traditional steel bars or welded mesh, improving construction efficiency and reducing costs.

Specialized High-Strength Synthetic Macro Fibers for Precast Concrete：

TopStar Concrete Synthetic Fibers is a leading manufacturer of high-strength polypropylene synthetic coarse fibers in China. We have been involved in many major projects in China, including large tunnels, underwater tunnels, and rail transit projects. We are the designated brand for high-strength synthetic coarse fibers in the field of precast concrete.
We have also participated in all experiments at Tsinghua University on the application of synthetic fiber materials in underground engineering, accumulating a large amount of effective data for underground engineering.
We will formulate different fiber performance indicators according to different projects and provide comprehensive support for customization. We are the preferred choice for synthetic coarse fibers in the high-strength field.

Crack-resistant concrete synthetic macro fibers for municipal engineering and private construction:

TopStar Concrete Synthetic Fibers uses concrete crack-resistant synthetic coarse fibers made from recycled polypropylene in the field of crack-resistant concrete to reduce fiber costs and thus lower project costs. The main function of this fiber is to suppress the occurrence of internal micro-cracks in concrete during the early stages of shrinkage hardening, which has a good effect on preventing seepage in concrete. It also reduces maintenance costs. Therefore, this recycled polypropylene crack-resistant synthetic coarse fiber is a cost-effective concrete crack-resistant fiber.

Special polypropylene synthetic fiber for fiber reinforced shotcrete：

Shotcrete has strict requirements for synthetic fibers. Therefore, the polypropylene synthetic fibers designed by TopStar Concrete Synthetic Fibers for shotcrete have strict requirements for fiber aspect ratio and carefully indented fiber surfaces. This allows the fibers to better integrate with the concrete, avoiding damage to the machinery and ensuring the concrete’s flowability is within an appropriate range.
This is based on our company’s experience and research data accumulated from a large number of tunnel and mining constructions. Therefore, the polypropylene synthetic fibers specially designed for fiber-reinforced shotcrete also support special customization according to construction requirements.
In the field of fiber-reinforced shotcrete, TopStar Concrete Synthetic Fibers remains an expert.

Polypropylene monofilament fiber：

Polypropylene monofilament fiber is an ultra-fine chopped engineering fiber made from polypropylene. It has stable performance, is easy to disperse, simple to construct, and is cost-effective, making it a commonly used crack-resistant product in concrete, cement, and mortar.

We provide comprehensive, follow-up services from design and sample production to testing and project implementation, ensuring the successful execution of every project.

1. TopStar Concrete Synthetic Fibers is a leading manufacturer in the field of high-strength polypropylene synthetic coarse fibers in China. We have our own renowned trademark, but we lack the capability to build a brand in overseas markets. Therefore, we support leading construction companies and building material manufacturers in overseas countries to create local brands. We support OEM production because the quality of our high-strength polypropylene synthetic coarse fibers is excellent and can fully support a brand.
