Product Description:Polyvinyl Alcohol
Polyvinyl Alcohol (PVA or PVOH) is a versatile, synthetic polymer produced by the hydrolysis of polyvinyl acetate.1 It is available in various grades, typically defined by its molecular weight and degree of hydrolysis (partially or fully hydrolyzed), which affect its solubility, viscosity, and other physical properties.2
PVA appears as an odorless, white to cream-colored granular powder.3 It is highly valued across industries for its excellent film-forming, emulsifying, adhesive, and water-soluble characteristics.4 PVA is widely used in paper, textile, adhesive, pharmaceutical, cosmetic, and advanced materials applications due to its non-toxicity and biodegradability.5
Key Features:
- Chemical Formula: 6 (varies with degree of polymerization)7
- CAS Number: 8
- Appearance: Odorless, white to cream-colored powder or granules9
- Solubility: Soluble in water (solubility dependent on grade and temperature); insoluble in most organic solvents10
- Properties: Excellent film-forming, strong adhesive, high tensile strength, and resistance to oils, grease, and most solvents11
- Biocompatible & Biodegradable: Suitable for eco-friendly and medical applications12
- Grades: Available in various molecular weights and degrees of hydrolysis (e.g., Partially Hydrolyzed, Fully Hydrolyzed)13
Applications
- Adhesives & Binders:
- Primary component in wood glues, paper adhesives, and as a binder in paper and textile production.14
- Used in construction as an additive to cement and mortars to enhance adhesion and flexibility.15
- Textiles & Paper:
- Applied as a sizing agent for warp yarn to increase strength and abrasion resistance during weaving.16
- Used in paper coating to improve surface strength, printability, and oil resistance.17
- Films & Packaging:
- Manufactured into water-soluble films for single-use packaging (e.g., laundry detergent pods, agricultural films).18
- Used as a protective coating with excellent barrier properties against oxygen.19
- Pharmaceuticals & Medicine:
- Functions as a tablet binder, coating agent, and lubricant in drug formulations.20
- Used in eye drops, wound dressings, and hydrogels for biomedical applications due to its non-toxic nature.21
- Industrial & Laboratory Use:
- Emulsifier, stabilizer, and dispersant in polymer emulsions and suspension polymerization.22
- Used in biochemical and research applications as a matrix or coating.23
Safety & Handling
- Non-Toxic: Safe for use in approved pharmaceutical and food-contact applications.24
- Precautions:
- Avoid inhalation of fine dust; dust-air mixtures may be combustible.25 Use adequate ventilation and a dust mask if required.
- Wear gloves and safety goggles when handling.26
- Avoid contact with strong oxidizing agents.27
- Storage:
- Store in tightly sealed, moisture-resistant containers in a cool, dry, and well-ventilated area.28
- Hygroscopic: Keep away from high humidity to prevent clumping and quality degradation.
