Description
Polyvinyl alcohol 6-98, fully saponified, is a synthetic polymer grade for laboratory and technical formulation work. With CAS number 9002-89-5 and EG number 618-340-9, it is characterised by a molar mass of approximately 47 000 g/mol and a density of about 1,19 g/cm³. supports convenient handling for method development, solution preparation, and film studies. Fully saponified polyvinyl alcohol is valued for its aqueous solubility behaviour and film-forming performance when used as a binder, protective colloid, or viscosity aid. This 6-98 grade from manufacturer Carl ROTH provides a defined saponification degree suited to reproducible experimental design. Applications commonly include coatings and adhesives research, emulsion stabilisation, paper and textile treatment trials, and broader polymer chemistry investigations. The intermediate molar mass range helps balance solution viscosity with handling ease. Laboratories and process developers can deploy the material in controlled workflows where consistent saponification and reliable film integrity are important selection criteria.

Questions about Polyvinyl alcohol, 6-98, fully saponified, 100 g, plastic
What is this article?
Polyvinyl alcohol, 6-98, fully saponified, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Polymers, PEGs & silicones, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A polymer, a PEG or a silicone is sold by molecular weight, or by viscosity, as much as by name. PEG 400 and PEG 4000 are different liquids and solids. A silicone oil's viscosity grades are the product range. The average molecular weight is the specification.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
