Key Benefits of Sodium Feldspar Powder in Plastic Applications

Enhanced Mechanical Strength and Wear Resistance

Our sodium feldspar powder significantly improves tensile strength and impact resistance, making it ideal for high-load plastic parts such as automotive components and electronic housings. It is especially well-received in the EV battery casing and connector housing sectors.

Improved Processing Flowability

For complex-shaped products like PVC pipes and PE films, our powder offers excellent dispersion and low viscosity characteristics, improving extrusion and injection molding efficiency while reducing energy consumption and equipment wear.

Increased Heat Resistance

With its high melting point and thermal stability, sodium feldspar enhances the heat resistance of plastics, making it suitable for engineering plastics and electrical enclosures used in elevated temperature environments.

Optimized Surface Finish

The fine and uniform particle structure helps fill micro-pores in plastic surfaces, resulting in smoother, higher-quality finishes. It is widely used in ABS housings and high-end appliance casings, where appearance and surface quality are critical.

Strong Market Demand and Reliable Supply Capability

Driven by rapid growth in industries such as new energy vehicles, smart home appliances, and consumer electronics, the demand for high-performance plastic raw materials continues to rise.

According to incomplete statistics, China’s demand for high-purity sodium feldspar powder surpassed 250,000 tons in 2025, with an expected annual growth rate of over 7% in the next five years.
