China's leading manufacturer of polyester fiber, offering comprehensive fiber solutions.
Michem Chemical Fibers Co., Ltd. is a leading manufacturer and exporter of high-performance polyester fiber with 12 years of expertise serving 50+ countries, including the USA, UAE, Australia, and South Africa. We’ve supplied polyester fiber to iconic projects like the Dubai Metro Extension, Australian Desalination Plant, and South African Highway Upgrade, where durability and cost-efficiency are critical.
Our polyester fiber is engineered in partnership with theZhejiang University Civil Engineering Departmentand meets strict global standards (ASTM C1116, EN 14889-2, ISO 9001). In this guide, we’ll break down how our polyester fiber solves concrete cracking and fatigue challenges, backed by third-party test data and real-world client results.
Polyester fiber is a synthetic reinforcement material made from high-tenacity polyethylene terephthalate (PET). Its unique combination of high modulus, alkali resistance, and low moisture absorption makes it ideal for concrete structures that require long-term durability, impact resistance, and resistance to harsh environmental conditions.
According to theInternational Federation for Structural Concrete (FIB), polyester fiber reduces concrete fatigue damage by 40% compared to standard polypropylene fiber, making it a cost-effective alternative to steel fiber for many applications.
We offer two high-performance polyester fibers, each designed to meet the specific needs of different concrete applications.

Polyester fiber is non-corrosive, lightweight, and easier to mix into concrete, eliminating the risk of rust staining and reducing handling costs. While steel fiber offers higher ultimate strength, polyester fiber is a cost-effective alternative for applications where impact resistance and long-term durability are key.
Yes. Our coated polyester fiber offers ≥98% alkali resistance, making it suitable for concrete structures exposed to harsh chemical environments (e.g., marine projects, sewage treatment plants). It meets ASTM C1116-20 standards for alkali resistance.
Absolutely! We provide 500g free samples to qualified global clients, along with detailed technical data sheets and test reports.
Polyester fiber creates a 3D reinforcement network in concrete, which absorbs energy from impact and thermal stress, preventing crack propagation. It also reduces plastic shrinkage cracking during the curing process, improving overall structural integrity.
