Main Application Scenarios for poly vinyl alcohol cas
-
Building Mortar & Putty: As a viscosity modifier and water-retention enhancer, poly vinyl alcohol cas improves elasticity, plasticity, and durability of cement- and gypsum-based systems. Synergy with cellulose ether agents boosts adhesion and crack resistance.
-
Adhesive Formulations: The colloidal and film-forming properties of pva polymer enable high-performance adhesives for wood, paper, textiles, and packaging.
-
Textile Sizing: Polyvinyl alcohol solutions provide a temporary protective layer for textile fibers during weaving, enhancing strength and reducing breakage.
-
Paper Industry: As a surface sizing agent, poly vinyl alcohol cas enhances printability, ink hold-out, and oil/grease resistance for specialty papers.
-
Instant Glue & Sealants: Its clear, fast-drying film with strong tackiness makes PVA a key base for rapid adhesives and construction sealants.
-
Medical & Pharmaceutical: Used for water-soluble film coatings and drug delivery barriers due to non-toxicity and biocompatibility.
-
Other Industries: Water-soluble packaging, ceramic binders, electronics encapsulation, and agricultural formulations.
Frequently Asked Technical Questions
1. What is the primary chemical composition of polyvinyl alcohol (PVA) powder (CAS 9002-89-5)?
Answer: It is a synthetic polymer with the repeating unit (C2H4O)n, created by the polymerization of vinyl acetate followed by hydrolysis. The degree of hydrolysis and polymerization defines its properties.
2. What are the common viscosity grades, and how are they selected?
Answer: Viscosity grades (commonly low: 4–10 mPa·s, medium: 20–40 mPa·s, high: 50–60 mPa·s at 4% solution, 20°C) are selected based on end-use: low for packaging, medium for building adhesives/mortar, high for industrial and textile applications.
3. What are the international quality standards for PVA powder?
Answer: Primary standards include GB/T 12010 (China), ASTM D1200 (USA), and EN ISO 2576 (EU), with requirements for purity, hydrolysis degree, residual acetates, ash content (<0.5%), and viscosity tolerance.
4. How should poly vinyl alcohol cas be stored and handled?
Answer: Store in sealed, moisture-free container111s at ambient temperature, away from acids or strong oxidizers. Avoid direct sunlight and high humidity to prevent clumping or degradation.
5. What packaging options are available for industrial applications?
Answer: Standard packaging includes 25kg woven bags with inner PE film, 500kg/1000kg jumbo bags, and custom packaging per client requirements. All packaging should be moisture-proof.
6. Can PVA powder be used with other polymers or additives?
Answer: Yes, it is commonly compounded with cellulose ethers, redispersible latex powders, superplasticizers, or silica fume to optimize construction formulation performance.
7. Are there any safety or environmental considerations for PVA usage?
Answer: Polyvinyl alcohol powder is non-toxic, biodegradable, and classified as a low-hazard substance. It is safe for building and industrial use, with minimal impact on the environment, aligning with global green building standards.
