Exceval™ – Kuraray’s water-soluble ethylene vinyl alcohol
Exceval™
Exceval™ is the trademark of Kuraray’s halogen-free hydro- phobic polyvinyl alcohol. Although Exceval™ is water-soluble similar to fully hydrolyzed Kuraray Poval™ grades it it absorbs less moisture at ambient temperature compared to our stand- ard polyvinyl alcohol grades. Hence Exceval™ is the polyvinyl alcohol of choice for water resistant emulsions, for D3 and D4 adhesives. Furthermore, Exceval™ produces coatings with excellent gas barrier properties towards oxygen, nitrogen and carbon dioxide, even in humid environments.
Mowiflex™ – Thermoplastic processable polyvinyl alcohol
Mowiflex™
Mowiflex™ is Kuraray’s polyvinyl alcohol- based polymer com- pound for thermoplastic processing. This nontoxic resin is water-soluble and forms clear, glossy films. It has high tensile strength and can be processed using conventional thermo- plastic technologies (blown film extrusion, injection molding, 3D printing, etc.). Moreover, Mowiflex™ can be colored, allow- ing processing as a highly concentrated masterbatch.
