Hebei Runhuabang New Material Technology Co., Ltd. provides premium Fine Acicular Wollastonite Powder, a naturally occurring calcium silicate mineral celebrated for its unique needle-like crystalline structure. Engineered to provide an optimal balance of strength, durability, and dimensional stability, our wollastonite is processed under a strict ISO9001 management system. This ensures a uniform particle size distribution and consistent chemical composition, making it an indispensable reinforcing agent for high-performance industrial applications.
Our high-purity wollastonite powder serves as a multifunctional performance booster across the ceramics, rubber, and plastics industries. By acting as a micro-reinforcement bridge within polymer chains and a fluxing agent in ceramic sintering, it significantly enhances tensile strength, reduces thermal shrinkage, and optimizes cost-efficiency. With an annual production capacity of 200,000 tons, we guarantee a stable, large-scale supply to global markets, supporting manufacturers in over 100 countries with tailored material specifications.

Unlike spherical fillers, its needle-like (acicular) structure provides micro-reinforcement, which significantly boosts rigidity, heat resistance, and dimensional stability while reducing mold shrinkage.
It acts as a fluxing agent that reduces sintering temperatures, enhances mechanical strength, and improves the whiteness and porosity of the finished ceramic ware.
Yes, it is an ideal functional filler for rubber, increasing tensile strength and wear resistance without compromising the flexibility of products like tires and conveyor belts.
Absolutely. Due to its chemical inertness and low volatile content, it is widely used in fire-resistant cement boards and green building panels.
We have a robust production capacity of 200,000 tons per year, ensuring we can meet large-scale industrial demands across global markets reliably.
Yes, our R&D team can adjust the particle size, aspect ratio, and surface treatments to match the precise requirements of your manufacturing process.
