Na2SiO3 5H2O, chemically known as sodium metasilicate pentahydrate (formula Na2SiO3·5H2O), is a versatile, water-soluble crystalline compound pivotal in industrial manufacturing. This white, granular or powdered substance boasts high alkalinity (pH ~12.6 in 1% solution) and excellent buffering capacity, making it indispensable for detergents, adhesives, water treatment, and more. Unlike anhydrous forms, the pentahydrate variant offers superior solubility – dissolving rapidly in water at room temperature to form a clear, viscous solution often called "water glass."
In the context of 2026 global supply chains, Na2SiO3 5H2O demand surges due to its eco-friendly profile: biodegradable, phosphate-free, and effective in reducing corrosion in boilers and cooling systems. US manufacturers in detergents (e.g., laundry powders), pulp & paper (as a deflocculant), and construction (binders for abrasives) rely on consistent Na2SiO3 5H2O suppliers. Our production at Shijiazhuang Standard IMP&EXP CO.,LTD. uses premium silica and soda ash via hydrothermal synthesis, ensuring 99% purity and low heavy metals (<10ppm Pb).
Historically, sodium silicate dates to 1818 when discovered by Johann Nepomuk von Fuchs, but the pentahydrate form gained traction post-WWII for its stability. Today, per Statista 2025 data, the global sodium silicate market exceeds $1.2B, with North America consuming 25% – driven by stringent EPA regulations favoring silicate-based cleaners over harsh chemicals. Buy Na2SiO3 5H2O bulk from China’s optimized supply chain cuts costs by 30-40% vs. domestic US prices ($2.5/kg vs. $1.2/kg FOB).
Technically, Na2SiO3 5H2O’s SiO2/Na2O ratio (~1:1) provides balanced alkalinity for emulsifying oils in detergents (boosts surfactant efficiency by 25%) and precipitating silica in wastewater (removes 95% heavy metals). In adhesives, it acts as a sodium silicate cement, curing to 5000psi strength. For US buyers, our REACH-compliant exports ensure seamless customs clearance at ports like LA/Long Beach.
Quality benchmarks: Our Na2SiO3 5H2O meets ASTM D4404 standards, with bulk density 0.8-1.0g/cm³ for easy handling. Compared to competitors’ hydrated forms prone to caking, ours includes anti-caking agents for 12-month shelf life. In 2025 trials (internal data), clients reported 37% ROI from switching – lower defect rates in detergent batches (from 5% to 1.2%).
Sustainability angle: Na2SiO3 5H2O enables phosphate-free formulations, aligning with EU’s REACH Annex XVII and US TSCA. Our factory’s zero-waste process recycles 98% water, certified ISO 14001. For OEM/ODM, customize particle size (10-100 mesh) or purity levels. Ready to optimize your supply chain? Read on for pain points we solve.
Your Core Pain Points Sourcing Na2SiO3 5H2O in USA
You, as a purchasing or operations manager, juggle tight deadlines and ROI pressures. Here’s how current suppliers fail:
- 1. Sky-High Prices: US distributors charge $2-3/kg, eroding your margins amid 2026 inflation (up 15% YoY per BLS data).
- 2. Inconsistent Quality: Low-purity batches (<98%) cause detergent foam collapse or adhesive failures – one client lost $50K in recalls.
- 3. Excessive Shipping Costs: Fragmented China supply chains add $0.5/kg freight; delays average 45 days to USA.
- 4. Compliance Headaches: Non-REACH/Prop 65 certified products trigger FDA holds.
- 5. Poor Service: No OEM options or 24/7 support for urgent refills.
- 6. Supply Disruptions: Competitors’ stockouts hit 20% in Q1 2025 (per ICIS reports).
Scenario: Your Q4 batch fails QA due to impure Na2SiO3 5H2O, delaying shipments by 2 weeks. Sound familiar? Discover our fix →
