Polyvinyl Alcohol GL 05 Product Description
Polyvinyl Alcohol (PVA) GL 05 is a water-soluble synthetic polymer that is widely used in various industrial applications due to its excellent film-forming, emulsifying, and adhesive properties. This particular grade, GL 05, is characterized by its low molecular weight and high degree of hydrolysis, making it suitable for applications that require a balance of solubility and film strength. PVA GL 05 is non-toxic, biodegradable, and environmentally friendly, which makes it a preferred choice in many sectors, including textiles, paper, and packaging.
Key Features:
- Water Solubility: Easily dissolves in water, forming a clear, viscous solution.
- Biodegradable: Environmentally friendly and breaks down naturally.
- Film-Forming Ability: Creates strong, flexible films that are resistant to oils and greases.
- Adhesive Properties: Acts as an effective adhesive in various formulations.
- Non-Toxic: Safe for use in food packaging and other sensitive applications.
Common Uses:
- Textile Industry: Used as a sizing agent and in the production of non-woven fabrics.
- Paper Industry: Acts as a coating and adhesive for paper products.
- Packaging: Utilized in the production of biodegradable films and coatings.
- Cosmetics: Employed in formulations for its film-forming and binding properties.
- Construction: Used in cement and mortar formulations to improve adhesion and flexibility.
