GPZP-10D
Silver Zirconium Phosphate · BIOX Series · Chemical-Resistant Grade
A sophisticated Silver Zirconium Phosphate inorganic antimicrobial — Ag⁺ ions immobilised in a crystalline zirconium phosphate lattice for sustained, broad-spectrum 24/7 protection. Thermally stable to 600–800°C. Non-yellowing. Chemically resistant. For plastics, coatings, medical devices & water systems.
GPZP-10D — Silver Zirconium PhosphateAntimicrobial Additive
GPZP-10D uses crystalline zirconium phosphate as its silver ion carrier — a rare, chemically resistant inorganic mineral that is stable in both acidic and alkaline environments. This makes it the preferred antimicrobial grade for applications involving aggressive chemical exposure, high temperatures, and long service life requirements that other carrier systems cannot sustain.
Silver Ions Locked in a Crystalline Zirconium Phosphate Lattice GPZP-10D is a sophisticated, high-performance Silver Zirconium Phosphate inorganic antimicrobial, engineered to provide an uncompromising defence against a broad spectrum of bacteria, fungi, and odour-causing microbes. At the molecular level, potent silver ions (Ag⁺) are strategically immobilised within a robust crystalline zirconium phosphate framework through ion-exchange. This controlled release mechanism allows silver to be delivered to the surface whenever microbial activity or moisture is present — providing a permanent, 24/7 antimicrobial barrier that remains active for the entire lifecycle of the treated product, making it the gold standard for long-term hygiene in high-demand industrial applications.
Thermally Stable to 600–800°C — Non-Yellowing by Design The inorganic nature of GPZP-10D provides decisive advantages over traditional organic biocides, particularly in extreme environments. It is inherently thermally stable up to 600–800°C and chemically inert — withstanding high-temperature polymer processing, industrial coating curing, and ceramic firing without decomposition or volatilisation. Critically, it is engineered to be non-yellowing, preserving the optical clarity and colour integrity of host materials. This makes it the technically preferred choice for white and pastel polymers, bright architectural coatings, transparent films, and precision medical-grade components where colour drift is commercially unacceptable.
Exceptional Chemical Resistance — Where Other Grades Fall Short What truly distinguishes GPZP-10D is its exceptional chemical resistance. The zirconium phosphate crystal lattice is unaffected by most acids, alkalis, organic solvents, and formulation additives — environments where zeolite structures can partially degrade and borosilicate glass matrices may be etched. This makes GPZP-10D the correct choice for applications involving aggressive chemical contact: solvent-borne industrial coatings, high-pH cementitious construction materials, water treatment components exposed to disinfectants, medical device plastics subjected to sterilisation chemicals, and epoxy systems where acid catalysts are present.
Versatile — Works Across 10 Industrial Applications GPZP-10D is characterised by excellent dispersibility and seamlessly incorporates into PP, PE, ABS, PVC, PET, PU, acrylics, and epoxies at 0.2–1.0% starting dosage — with up to 2.0% for high-exposure applications. Its fine particle size (D50: 1–5 µm, >99% inorganic matrix purity) ensures uniform distribution without compromising mechanical properties, tensile strength, or processing rheology. From water-handling systems and medical-grade plastics to performance textiles, industrial sealants, and food-contact surfaces, GPZP-10D delivers a scientifically rigorous and durable antimicrobial solution for manufacturers committed to the highest standards of biosafety and material longevity.

Long-Lasting Antimicrobial Performance
Controlled silver ion release from the glass matrix ensures continuous antibacterial and antifungal protection throughout the product's service life — not a short-lived burst at initial production.
Broad-Spectrum Activity
Effective against a wide range of bacteria and fungi — grade-dependent efficacy covers common pathogens and spoilage organisms including mold, mildew, and odour-causing microbes.
High Thermal Stability for Polymer Processing
Stable up to 300°C — suitable for PVC, PE, PP, and standard engineering plastic compounding, extrusion, and injection moulding processes without loss of antimicrobial activity.
Reduces Mold, Mildew Staining & Odour
Inhibits microbial-induced surface staining, discolouration, and odour development — particularly valuable in construction materials, sealants, and polymer products in humid environments.
Low Volatility — Long-Term Retention
Silver permanently anchored within the glass network does not evaporate, migrate, or volatilise under normal use conditions — ensuring reliable, measurable protection over the full product lifetime.
Built for Industrial Material Protection
Designed specifically for industrial applications in plastics, coatings, construction chemicals, and sealants — not a consumer surface treatment, but a durable in-built solution.
Alkali-Stable in Cementitious Systems
Unlike organic biocides that degrade rapidly in high-pH mortar and grout environments, the inorganic glass matrix resists alkaline conditions — maintaining efficacy in cement-based construction materials.
Non-Leaching Performance
Silver ions release at a controlled rate from within the glass structure — not freely leaching. This prevents rapid depletion and ensures the antimicrobial effect is sustained rather than consumed at the surface.
Inorganic — No Organic Residues
No VOCs, no organic breakdown products, no reactive intermediates. GPSG-10DL is a purely inorganic antimicrobial system — compatible with formulations where organic biocide restrictions apply.
Wide System Compatibility
Compatible with PVC, PE, PP, engineering resins, waterborne and solvent-borne coatings, acrylic and hybrid sealants, tile grouts, polymer mortars, and composite building boards.
