Polyvinyl alcohol (PVA) 100-70 is a specific grade of PVA that possesses several advantages in various applications. Here are some of the advantages of PVA 100-70:
1. Water Solubility: PVA 100-70 is highly water-soluble, making it convenient for various formulations where dissolution in water is required. It readily disperses in water to form clear solutions.
2. Film Formation: PVA 100-70 can be used to create thin films with excellent mechanical strength and flexibility. It forms transparent, smooth, and uniform films, making it suitable for applications such as coatings and packaging.
3. Barrier Properties: PVA 100-70 exhibits good barrier properties against gases, including oxygen and aromas. This makes it useful in packaging applications, particularly for food and pharmaceutical products, where it helps to maintain product freshness and extend shelf life.
4. Adhesive Properties: PVA 100-70 can be utilized as an adhesive or binder in various industries. It forms strong bonds with a wide range of substrates, including paper, wood, fabric, and plastics. Its adhesive properties make it useful in applications like paper laminating, textile sizing, and bookbinding.
5. Biodegradability: PVA 100-70 is biodegradable under certain conditions. This property makes it an environmentally friendly choice compared to synthetic polymers that are non-biodegradable.
6. Compatibility: PVA 100-70 is compatible with many other polymers, resins, and additives, allowing for easy blending and formulation in combination with other materials. This versatility enhances its applications in various industries.
7. Low Toxicity: PVA 100-70 is considered non-toxic and safe for use in consumer products. It is widely used in applications involving direct contact with the human body, such as in pharmaceuticals, personal care products, and medical devices.
8. Stability: PVA 100-70 exhibits good thermal stability, maintaining its properties over a wide temperature range. It can also withstand exposure to UV light without significant degradation, making it suitable for outdoor applications.
