Polyvinyl alcohol 2488 (PVA 2488) is a versatile and widely used polymer used in various industries such as construction, textile, paper and agriculture. Polyvinyl alcohol (PVA) is a heavy polymer that usually appears as a non-toxic, tasteless and non-polluting white or pale yellow flocculent, flaky, granular or powder. This polymer is a water-soluble resin with good chemical stability and has good adhesion, film-forming, insulation, oil resistance, and wear resistance. However, does PVA 2488 have the necessary performance or not? In this comprehensive guide, we examine the various aspects of purchasing polyvinyl alcohol, its properties and uses.
Getting to know the characteristics of polyvinyl alcohol 2488
Polyvinyl alcohol 2488 is a nonionic polymer with high molecular weight and soluble in water. It is known for its excellent solubility and adhesive properties. “2488” in its name indicates its average polymerization degree and hydrolysis level. It is in the normal molecular weight range of 20,000 to 30,000. Next, let’s check the features of PVA 2488.
1. High solubility:
Due to its relatively low molecular weight, PVA 2488 exhibits excellent solubility in water. For this reason, it allows easy formation of uniform solutions. This feature is preferred for its safety in water-based solution applications.
2. Excellent solvent compatibility:
Polyvinyl alcohol 2488 can be dissolved in some organic solvents such as methanol and ethanol. Because it offers more flexibility and application choices. This feature is useful in scenarios where water-based solutions may not be suitable.
3. Cohesive properties of polyvinyl alcohol 2488:
During the drying process, PVA 2488 forms colloidal solutions rapidly and exhibits strong adhesive properties. This property makes it suitable for adhesive preparation and ensures safety in bonding applications.
4. Biodegradability:
An important safety feature of PVA 2488 is its ability to rapidly hydrolyze and degrade in the natural environment, which minimizes its risk to the ecosystem.
Application of polyvinyl alcohol
Polyvinyl alcohol 2488 is a special type of polyvinyl alcohol polymer with unique properties. PVA is a water-soluble synthetic polymer obtained by polymerization of vinyl acetate. PVA 2488 has properties that make it suitable for various industrial applications. Here are several uses of polyvinyl alcohol:
1. Glue:
Polyvinyl alcohol 2488 is widely considered a key component in the formulation of adhesives. This adhesion is used on different levels and often in woodworking, paper gluing and packaging. PVA adhesives are recognized for their strong bonding capabilities, flexibility, and user-friendliness.
2. Paper industry:
PVA 2488 is a surface measuring agent in the paper industry. It improves the surface properties of paper and increases its printing ability, smoothness and ink absorption. Papers coated with PVA 2488 are often used for high quality printing.
3. Textile industry:
In the textile industry, PVA 2488 is a measuring agent for yarns. It gives strength and flexibility to the thread and facilitates the weaving process. In addition, the size of PVA increases the fabric’s resistance to wear.
4. Materials and building materials:
Polyvinyl alcohol 2488 is used in the construction industry as an additive in cement and mortar formulations. It increases the adhesion of these materials to different surfaces and improves their strength and durability. PVA is often added to tile adhesives, joint compounds, and plaster.
5. Emulsion polymerization:
PVA 2488 is a precursor in the production of polyvinyl acetate (PVAc) through emulsion polymerization. PVAc is used in the manufacture of various products including paints, coatings and adhesives.
6. Packaging films:
PVA films derived from PVA 2488 are used in the packaging industry. These films are water soluble and are used to package water soluble detergent pods, agrochemicals and other products where controlled release or easy dissolution capability is required.
7. Medical and pharmaceutical applications:
Water-soluble PVA films are used in the medical and pharmaceutical industries for applications such as dissolvable packaging for drugs and capsules. These films offer a convenient and safe method for administering specific types of medications.
8. Coatings and resins:
PVA 2488 is used in the formulation of coatings and resins and contributes to their film-forming properties. This is especially important in the production of water-based paints, varnishes and other coating materials.
9. Mold release agent:
Polyvinyl alcohol 2488 can be used instead of a mold release agent in the production of some molded products. Its water-soluble nature makes it easy to release from the mold and facilitates the manufacturing process.
Tips for buying polyvinyl alcohol
Polyvinyl alcohol 2488 is one of the most widely used types of synthetic resins. Due to its unique characteristics, it is used in various industries including textiles, adhesives, polymer films and paper products. This material is particularly important with its high adhesive strength, resistance to solvents and water solubility. In the following, we will examine the key points for purchasing this product to ensure that you choose the best quality and most affordable options.
- Intended Application: Make sure PVA 2488 is suitable for the specific project or application you have in mind. This type of glue is used for applications such as gluing paper, wood, cloth and other things.
