- PVA 2488 (Partially Hydrolyzed, cold water soluble) – Designed for tile adhesive, waterproof mortar, high-viscosity construction glue, and textile medium-high count warp sizing.
- PVA 1799 (Fully Hydrolyzed, 98–99% hydrolysis, viscosity 22–30 mPa·s, hot water soluble above 80°C) – Typical applications include textile sizing, paper coating, optical film raw material, and oil well water shutoff.
- PVA 2499 (Fully Hydrolyzed, high viscosity 45–58 mPa·s) – Used for high-count fabric sizing, high-strength PVA fiber, PVB resin and film for automotive & photovoltaic, and water-resistant coatings.
- PVA 0588 (Partially Hydrolyzed, low viscosity, cold water soluble) – Functions as a cosmetic thickener, agricultural seed coating, printing wetting agent, and protective colloid for VAE emulsion.
- PVA 0599 (Fully Hydrolyzed, low viscosity) – For pharmaceutical coating, slow-release medical substrates, and fine chemical dispersants.
Beyond PVA, the company provides VAE copolymer emulsions (models 705, 706, 707, 707H) with distinct viscosity and solid content profiles, and redispersible polymer powder for dry-mix mortars and tile adhesives.
Application Scenarios Across Key Industries
Construction Industry
In interior wall putty, PVA 1788 or 2488 is cold-water dissolved and mixed with fillers, acting as a film-forming agent, binder, anti-crack additive, and water retention agent. The operating environment includes ambient temperatures of 25–38°C and high humidity. Equipment such as vertical stirring tanks and powder mixers are used. Special requirements include using only 87–89% partially hydrolyzed grades to ensure compatibility with alkaline cement systems, plus low formaldehyde and low VOC levels to meet global indoor building material standards.
Textile Industry
For textile warp sizing, fully hydrolyzed PVA 1799 is dissolved in hot water (80–95°C) in a continuous sizing machine, coating the yarn surface to increase tensile strength, reduce loom breakage, and lubricate fibers. The sizing tank operates at 80–95°C under continuous 24-hour production. The desizing wastewater is biodegradable. Supporting equipment includes hot water dissolving kettles, automatic sizing machines, and high-speed air jet looms.
Paper & Packaging Industry
For paper surface sizing, PVA 1788 is cold-water dissolved and applied via an online sizing machine at high speed (300–800 m/min) and oven temperatures of 90–120°C. It improves surface smoothness, printability, oil resistance, and tensile strength while preventing ink penetration. Special requirements include low foam and stable viscosity under high-speed stirring, and for food packaging cartons, low odor and food indirect contact certification.
Global Market Presence and Export Performance
HOPEWAY exports to more than 40 countries and regions worldwide. Export revenue accounts for 27.17% of total turnover (USD 1.1 billion annual revenue). Key overseas markets include Southeast Asia (largest for RDP), South Asia (India – No.1 single overseas country for PVA), Latin America, Europe, the Middle East & Africa, and developed markets in North America, Japan, and South Korea for specialty optical PVA and automotive-grade PVB. The company supports flexible trade terms (FOB, CFR, CIF, EXW) and payment methods (T/T, L/C).
Market Trends and Industry Position
According to UN Comtrade data, China exported approximately USD 366.6 million worth of PVA in primary forms in 2024, making it the world's leading exporter. Domestically, PVA consumption is dominated by polymerization aids (38%), fabric sizing (20%), and adhesives (12%). The global market for PVA films used in packaging is expanding at a CAGR of 7.1% (2026–2034), driven by water-soluble and biodegradable packaging demand. HOPEWAY's investment in PVA optical film (for LCD polarizers) and PVB interlayer film positions it to capture growth in high-margin specialties that traditionally relied on overseas suppliers.
Comparison with Traditional Alternatives
Compared to starch-based sizing agents, PVA offers higher film strength, better abrasion resistance, and easier desizing in textile applications. However, an honest limitation is that fully hydrolyzed PVA grades require dissolution in hot water (above 80°C), which can increase energy consumption for cold-process lines. Partially hydrolyzed grades (cold water soluble) mitigate this but may not provide the same water resistance. HOPEWAY's comprehensive range allows specifiers to match the right grade to their process conditions.
Future Outlook
As environmental regulations tighten and demand for sustainable packaging rises, water-soluble PVA films and biodegradable polymer composites will gain traction. HOPEWAY's ongoing development of customized formulas for optical, medical, and construction specialty applications, combined with its massive production scale and in-house R&D capability, positions it as a reliable long-term partner for global buyers seeking quality and consistency. The company also exports complete PVA production technology overseas, demonstrating the depth of its manufacturing expertise.
Frequently Asked Questions
What is polyvinyl alcohol (PVA) and how is it manufactured?
Polyvinyl alcohol (PVA) is a water-soluble polymer manufactured by alcoholysis of polyvinyl acetate. It appears as white powder or flake and is classified into fully hydrolyzed and partially hydrolyzed categories. Fully hydrolyzed grades require hot water (above 80°C) for dissolution, while partially hydrolyzed grades are cold water soluble.
What are the main product lines offered by HOPEWAY?
HOPEWAY's main products include polyvinyl alcohol (PVA), Vinyl Acetate Ethylene (VAE) Copolymer Emulsion, Redispersible Polymer Powder (RDP), PVA Film, PVA Fiber, and PVB Resin & Interlayer Film. The annual production capacity of polyvinyl alcohol reaches 350,000 tons.
Which grades of PVA are suitable for construction applications?
For interior wall putty and construction glue, only partially hydrolyzed PVA grades with 87–89% hydrolysis (e.g., PVA 1788 and PVA 2488) are applicable because they are cold water soluble and compatible with alkaline cement systems. Fully hydrolyzed PVA is not recommended for such uses.
How does HOPEWAY ensure product quality and certification compliance?
The company follows strict full-process quality inspection and provides complete MSDS, TDS, and third-party test reports. All products comply with EU EPD, ISCC, and EcoVadis environmental standards. For pharmaceutical and food contact applications, specific low-impurity grades are available.
What is the global reach of HOPEWAY's exports?
HOPEWAY exports to more than 40 countries and regions. Major markets include Southeast Asia, South Asia (India is the No.1 single overseas country for PVA), Latin America, Europe, the Middle East & Africa, and developed markets in North America, Japan, and South Korea. Export revenue constitutes 27.17% of total turnover.
