Our PVA solution is produced by dissolving our own PVA with water. In consideration that some customers do not have their own dissolution equipment, these aqueous solutions are typically formulated according to the specifications of our customers, and thereby adding values and further improving the business image.
| Category | Details |
|---|---|
| Chemical Formula | (C₂H₄O)ₙ (Polymer of vinyl acetate hydrolysis) |
| Key Properties | – Solubility: Water (cold/hot), partially in DMSO/ethylene glycol – Viscosity: 5-100 cP (varies with concentration/molecular weight) – pH Stability: 4-8 (hydrolytic degradation outside range) |
| Solution Preparation | – Concentration: 5-20% w/v – Dissolution: Stirring at 80-90°C – Stabilizers: Added to prevent gelation (e.g., surfactants) |
| Primary Applications | – Textiles: Warp sizing, fabric stiffening – Paper: Surface coating, adhesive binder – Medical: Ophthalmic solutions, drug delivery matrices – Packaging: Water-soluble films, eco-friendly pouches |
| Advantages | – Film-forming: Clear, flexible coatings – Adhesive: Strong tack without toxicity – Biocompatibility: USP Class VI certification (medical use) |
| Environmental Profile | – Biodegradability: Anaerobic digestion possible – Recyclability: Combustible with low ash residue – VOC-free: Safe for indoor applications |
| Market Trends | – Growth Drivers: Eco-packaging demand, 3D printing (support material) – Challenges: Cost competition from synthetic alternatives – Innovations: Cross-linked PVA for enhanced durability |
| Safety & Handling | – Toxicity: Low (LD₅₀ >5g/kg oral) – Storage: Cool, dry conditions (prevents microbial growth) – Disposal: Incineration or wastewater treatment (check local regulations) |
Note: High molecular weight grades (>100kDa) offer superior film strength. Thermal gelation occurs above 95°C.
