Key milestones include:
- 1991: Company founded in Chongqing.
- 2017: Reorganized into a joint-stock company, which marked an important corporate restructuring step ahead of later capital-market activity.
- 2023: Listed on the Shenzhen Stock Exchange, providing the company with broader financing access and public-market visibility.
In addition to domestic expansion, the company has developed overseas business channels and production-linked presence in multiple regions. Industry and investor materials indicate that CPIC has maintained or expanded facilities and sales activity in places such as Brazil and Bahrain, alongside operations in Chongqing, Zhuhai, and Changzhou.
Business Operations and Segments
CPIC’s core business is centered on glass fiber and glass-fiber-based composite reinforcement materials. The company’s operations can be understood in two broad layers:
- Upstream materials production: melting, fiberizing, sizing, and forming glass fiber products.
- Downstream reinforcement products: converting fibers into fabrics, mats, yarns, and other formats suitable for composite processing.
The company is also described as part of the glass-fiber new materials industry associated with the Yuntianhua group ecosystem, which indicates a strategic link to broader industrial materials resources and supply chains.
A notable feature of CPIC’s model is its mix of industrial scale and technical specialization. Rather than selling general-purpose commodity plastics, it supplies reinforcement materials that are integrated into finished composite structures by processors and OEMs in multiple industries.
Products and Technologies
CPIC’s portfolio covers a range of glass-fiber formats used in composite manufacturing. Major product categories include:
- Direct roving and assembled roving
- Chopped strands
- Glass fiber yarns and bulked yarn
- Woven fabrics
- Multiaxial fabrics
- Fiberglass mats
- Milled glass
Technically, these products serve different processing routes and performance requirements:
- Roving is commonly used in pultrusion, filament winding, and composite layup.
- Chopped strands are often compounded into thermoplastics to improve stiffness and dimensional stability.
- Woven and multiaxial fabrics are used where directional strength, fatigue resistance, or structural integrity is required.
- Mats are used in molding applications and as reinforcement layers in composites.
The company is also associated with alkali-free glass fiber and ECR-glass production, both of which are important in applications requiring corrosion resistance, durability, and improved chemical performance. Financial and industry sources indicate that CPIC has worked to extend its product development into higher-value categories, including new fabric formats under development.
