Polyvinyl Alcohol Grade 49-88
PVOH Solution PreparationPolyvinyl Alcohol Grade 49-88 is a high-viscosity (49 cps for a 4% solution) and partially hydrolyzed (88%) water-soluble polymer. Equivalent to PVOH5042, Elvanol® 50-42, SELVOL 540, and POVAL 49-88, it dissolves in cold water but benefits from heating or warm water for complete dissolution. This polymer offers high tensile strength, tear resistance, and excellent properties as a disperser and stabilizer. Applications include stabilizing vinyl acetate, polystyrene, and polyvinyl chloride emulsions, re-moisturizing adhesives, temporary binders for ceramics, water-soluble films, paper adhesives, photosensitive coatings, and as a soil anti-redeposition agent. PVOH 49-88 is also widely used in personal care, construction, textile, and emulsion industries and is a key ingredient for making slime.

Clear Flexible PVC Tube
This clear plastic tube is crafted from flexible PVC (Poly Vinyl Chloride), typically featuring an inner diameter of 2 millimeters and an outer diameter of 4 millimeters. Due to the elastic nature of PVC and manufacturing tolerances, both the inner diameter (ID) and outer diameter (OD) may vary by up to 0.5 mm. This variability ensures adaptability across different applications but should be considered when precision is critical. PVC tubing is commonly used to demonstrate the equalization of liquid levels in interconnected vessels and for transporting liquids in experimental setups, as well as conveying fuel and lubricating oils in various types of machinery. Furthermore, this tube’s flexibility and size range make it suitable as a coupling for small DC motor shafts, generators, propellers, and similar components, enhancing its versatility in both experimental and mechanical applications.
