Polyvinyl Alcohol (PVOH), Pure Solid Granules, Made in Germany, Packed in the UK
Polyvinyl alcohol (PVOH, PVA, or PVAl) Water soluble, non-toxic, pure polymer, made in Germany, packed in the UK. Polyvinyl alcohol (PVOH, PVA, or PVAl) is a non-toxic water-soluble synthetic polymer used in many applications, such as paper-making, textiles, and a variety of coatings.It is effective in film forming, emulsifying, and has an adhesive quality. It has no odour and is not toxic, and is resistant to grease, oils, and solvents.Specifications:CAS Number: 25213-24-5Molecular Formula: (C4H6O2.C2H4O)xPhysical Form: Pure, Solid, White, Odourless Granules.All orders are carefully packed in resealable plastic bags and padded envelops or bubble wrap sheet. Grade 8-88:Average Molecular Weight: 67,000 Degree of Polymerization: 1,400 Degree of Hydrolysis: 88% Viscosity (of 4% aqueous solution): 8 mPa.s (viscosity is proportional to concentration)Grade 18-88:Average Molecular Weight: 130,000 Degree of Polymerization: 2,700 Degree of Hydrolysis: 88% Viscosity (of 4% aqueous solution): 18 mPa.s (viscosity is proportional to concentration) Note:The two grades of this material have similar solubility and other physical properties, as solid materials. However, they are differ in the molecular weight, and hence the viscosity of the solution. The grade 18-88 gives higher viscosity in solution (e.g. 18 mPa.s) than that of the grade 8-88 (e.g. 8 mPa.s), when using similar weight concentration (e.g. 4% in water). Lower solution viscosity means easier preparation and application. Due to the higher molecular weight of grade 18-88, it gives stronger mechanical properties of the obtained dried film than that of the grade 8-88; however, the chemical properties of both stay the same. ————————————————————————————————————For general-purpose use. Not food grade. All orders are carefully packed in resealable plastic bags and padded envelops or bubble wrap sheet. Store in a cool dry place in a closed container. Main properties of Polyvinyl alcohol are: • Excellent film formation • High bonding power • Good barrier properties • Can be combined with many reactants • Water-soluble • Biodegradable and recyclable • No health hazards PVOH is used in the following applications, just to name a few:• Abrasives • Adhesives • Building materials • Ceramics • Cosmetics • Protective colloid in emulsion polymerization • Food packaging • Paper • PVC production and compounding • Textiles • Thermoplastic processing • Oil field cementing • Glass fibre Product of Germany, packed in the UK by ME Scientific Engineering Ltd.Please email us if you require a copy of the MSDS.
