Its film-forming ability produces clear, strong, and printable films, making it a versatile polymer for advanced industrial and professional applications. ## Description Product description Construction Materials Polyvinyl alcohol is a key ingredient with excellent adhesive and water-resistant properties. It is commonly used for bonding materials such as paper, fibers, plastics, and metals. PVA Coatings Utilized in various dyeing methods, including solution dyeing, conventional dyeing with regular dyes, development of specific dye structures, and special dyeing techniques. PVA Skin Adhesive PVA adhesives are widely used for their superior bonding properties and weather resistance, making them applicable across many industries. White granules or powder. Soluble in water or capable of swelling, but insoluble in most organic solvents, lubricants, or grease. PVA is hygroscopic. Does not melt upon heating and undergo dehydration and decomposition at around 150°C, turning yellow. PVA degrades slowly at 100°C and rapidly degrades at 200°C. It exhibits light stability. It degrades in strong acids, and softens or dissolves in weak acids or alkalis. Contact with strong oxidants may result in combustion or explosion. Mixture may be formed. Due to its excellent viscosity and high safety, Polyvinyl alcohol is commonly used in the production of coal slime. The degree of polymerization and alcoholysis are the two main factors that determine its physical properties. It is used as a dispersant and protective colloid in vinyl chloride polymerization. It can also be used in the production of polyvinyl formal and vinylon fibers. It serves as an adhesive for metals, rubber, leather, and other materials, as well as a binding adhesive and fabric sizing agent. Review: Excellent, but be sure you know what you are buying - This is excellent PVA, and exactly what it should be. I read another review complaining that the product was faulty because it could not be dissolved, so I just wanted to tell you that PVA has to be dissolved by stirring it in hot water (maybe 20 degree under boiling) for about 20 minutes. This is just the nature of hydrolyzed PVA. It has nothing to do with the brand or the quality (both are excellent), but just the chemistry of this compound. I can only advise you not to buy it if you don't know what it is and how to work with it. But if you do, and you need to work with PVA, this is the best deal I have found from a reputable company. Review: Works - Works like it should ## Features - 1. Molecular Formula: (C2H4O)n. Alcoholysis degree: 88%; Molecular weight: 105600. Solubility: the solubility of PVA varies depending on its alcoholysis degree and polymerization degree. - 2. Polyvinyl alcohol is a water-soluble polymer derived from the hydrolysis of polyvinyl acetate, without the need for monomer polymerization. It appears as a white powder. - 3. Thermal Stability: PVA softens when heated and shows no significant change below 40°C. Prolonged heating above 160°C causes gradual discoloration. At temperatures above 220°C, it decomposes to water, acetic acid, acetaldehyde, and butene. - 4. PVA is almost unaffected by weak acids, weak alkalis, or organic solvents, and it exhibits high oil resistance. PVA is a low-viscosity polymer, and its aqueous solution is very stable at room temperature, with no degradation during storage. - 5. Film-Forming Properties: Due to strong intermolecular adhesion, PVA easily forms films that are colorless, transparent, and exhibit excellent mechanical strength. The film surface is smooth, non-sticky, and has good solubility. PVA films have high light transmittance, high moisture permeability, and excellent printability. ## Technical Specifications | Specification | Value | |---------------|-------| | % Assay of Chemical(s) | 88 | | ASIN | B01MRLPP5J | | Best Sellers Rank | #274,053 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #387 in Analytical Reagents | | Brand | EASTCHEM | | Brand Name | EASTCHEM | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 85 Reviews | | Item Form | Powder | | Item Volume | 2488 Liters | | Item Weight | 1 Pounds | | Manufacturer | EASTCHEM | | Package Information | Bottle | | Part Number | PVA | | Percentage assay | 88 | | UPC | 713902738758 | | Volume | 2488 Liters | ## Product Details - **Brand:** EASTCHEM - **Item Weight:** 16 ounces - **Item Volume:** 2488 Liters - **Percentage assay:** 88 - **Package Information:** Bottle ## Images ![PVA 2488L(V50) Powder Polyvinyl Alcohol (500g) - Image 1](https://m.media-amazon.com/images/I/61kefYUPqdL.jpg) ![PVA 2488L(V50) Powder Polyvinyl Alcohol (500g) - Image 2](https://m.media-amazon.com/images/I/71HowDH0w-L.jpg) ![PVA 2488L(V50) Powder Polyvinyl Alcohol (500g) - Image 3](https://m.media-amazon.com/images/I/61n1xfpK7KL.jpg) ![PVA 2488L(V50) Powder Polyvinyl Alcohol (500g) - Image 4](https://m.media-amazon.com/images/I/81MAYJlE6hL.jpg) ![PVA 2488L(V50) Powder Polyvinyl Alcohol (500g) - Image 5](https://m.media-amazon.com/images/I/71UICyLOlwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, but be sure you know what you are buying *by T***T on September 30, 2025* This is excellent PVA, and exactly what it should be.

It makes slime *by R***N on April 14, 2018* Works great for slime. This will make 2.5L of 4% PVA solution. This makes a BUNCH of slime. You will also need a 4% solution of sodium tetraborate (borax). Mix the PVA and borax solution at ≈ 200:15. Stir like the devil and you get special effects grade slime. Add food coloring, glitter, powdered mica, highlighter fluid or whatever to make the look you need. ## Frequently Bought Together - PVA 2488L(V50) Powder Polyvinyl Alcohol (500g) - Polyvinlypyrrolidone, Povidone, (PVP-40),k-30, Ultra Pure, 100 Grams - Polyvinyl Alcohol High Purity Powder 100g Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/44571920-pva-2488l-v50-powder-polyvinyl-alcohol-500g](https://www.desertcart.tn/products/44571920-pva-2488l-v50-powder-polyvinyl-alcohol-500g) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-07*
