Product Overview
As a China-based manufacturer, Alfa Chemical supplies high-purity Poly(2-ethyl-2-oxazoline) (PEOX, CAS 25805-17-8), a water-soluble, non-ionic polymer widely used in coatings, adhesives, and research applications. Also known as PEtOx or polyethyloxazoline, this amorphous polymer exhibits good temperature stability with a glass transition temperature around 70°C.
PEOX is supplied as off-white granules or powder with a purity of ≥ 99% and a viscosity of 60-80 cSt (10% in H₂O). It is soluble in water and common organic solvents including DMF, lower alcohols, methyl ethyl ketone, and methylene chloride. The polymer is available in multiple molecular weight grades (5,000 / 50,000 / 200,000 / 500,000) to suit different formulation requirements.
Key applications include adhesion promoters in coatings, heat-sealing and remoistenable adhesives, rheology modifiers, and non-clinical research. The product is comparable to Aquazol® grades, offering similar properties at competitive pricing. For similar organic polymers and specialty chemicals, explore our related product range.
