China Weighting Glass Beads Suppliers - High-Quality Factory-Direct Density Control Solutions

Weighting glass beads, manufactured in China, are small spherical glass particles specifically designed for various applications, including filling, weighting, density adjustment, and counterweight solutions. Produced from high-quality soda-lime glass, these beads are processed to ensure they are smooth, clean, and uniform in size. With a density greater than many plastic fillers and textile fibers, weighting glass beads are ideal for manufacturers seeking compact weight, stable filling performance, and excellent flowability. In both consumer and industrial products, precise weight distribution is crucial. Weighted blankets benefit from evenly distributed filling materials that provide gentle pressure, while stuffed toys and craft items require stable and clean fillers to enhance tactile feel and maintain product shape. Additionally, plastic, rubber, and composite products may need density control to optimize performance, stability, or counterweight functionality. The round shape, high bulk density, chemical stability, and consistent particle size of weighting glass beads make them an excellent choice to meet these needs. As a leading supplier, WANCHENG MINERAL offers weighting glass beads from our factory to global customers across various sectors, including textile products, household items, toy filling, craft filling, plastic fillers, rubber products, sports equipment, and industrial counterweight applications. We provide a range of particle sizes, packaging options, and customized grades tailored to meet customer specifications. Our commitment is to deliver stable quality, a clean appearance, good flowability, and reliable bulk supply.

Frequently Asked Questions

What is the main chemical component of this glass?

The main chemical component is Silicon Dioxide (SiO2), which typically accounts for 70% to 73% of the total composition and serves as the primary glass network component.

What role does Sodium Oxide (Na2O) play in glass formulation?

Sodium Oxide (Na2O) makes up about 12% to 15% of the composition. Its primary function is to facilitate the melting and processing of the glass.

How do Calcium Oxide (CaO) and Magnesium Oxide (MgO) contribute to glass quality?

Calcium Oxide (CaO, 7% - 10%) improves the overall stability of the glass, while Magnesium Oxide (MgO, 2% - 4%) is added to enhance its durability.

Why is Aluminum Oxide (Al2O3) included in the composition?

Aluminum Oxide (Al2O3) is present in small amounts (0.5% - 2.0%) to significantly improve the chemical resistance of the glass.

Is Iron Oxide (Fe2O3) present in the glass, and what is its limit?

Yes, Iron Oxide (Fe2O3) is present in the glass, but it is kept strictly as a controlled impurity with a typical content of less than or equal to 0.5%.
