ELVANOL

Elvanol™ 71-30 by Kuraray is a fully hydrolyzed polyvinyl alcohol. It shows excellent resistance to oil, grease, water and solvents. It offers high tensile strength, flexibility, high oxygen barrier and film forming characteristics. On evaporation of water, transparent films are formed which have high tensile strength and tear resistance. The binder characteristics of Elvanol® 71-30 offer excellent adhesion to porous and hydrophilic surfaces. It is widely used in the paper industry at the size press and calendar stack, and in adhesives tackified with boric acid. Recommended for paper and paperboard, as a component in industrial adhesives for bonding paper, textiles, leather, in bag adhesives and pastes. It is also used in corrugated container board, laminating adhesives which are used in the manufacture of solid fiberboard, linear board, spiral wound tubes and cores and laminated specialties. It complies with FDA.

Elvanol™ 90-50 by Kuraray is a fully hydrolyzed, medium-to-low viscosity polyvinyl alcohol. Provides high film strength and binding power in relatively low -viscosity systems. Offers oil-, grease-, water and solvent resistance. It combines efficient binding with excellent high shear rheology, controls backside lint and surface debris and provides superior holdout. It is compatible with modified starches. Used in adhesives for porous substrates including paper and paperboard, hot-water soluble film, and as a binder for pigments or other solid particles. It is particularly useful as a pigment binder for ceiling tile primers. Elvanol™ 90-50 complies with FDA regulation.

Elvanol™ 80-18 by Kuraray is a copolymer of polyvinyl alcohol and another monomer. It possesses excellent film formation, emulsifying power and adhesion to substrates. It is produced by converting polyvinyl acetate into polyvinyl alcohol through the saponification process. Elvanol™ 80-18 is suitable for use in adhesives.

Elvanol™ 75-15 by Kuraray is a medium low viscosity, fully hydrolyzed copolymer grade of polyvinyl alcohol. Its unique structure imparts improved viscosity stability and gel resistance to aqueous solutions while maintaining excellent film properties and adhesive strength. It shows excellent resistance to oil, grease and solvents. Elvanol™ 75-15 is used as a secondary, or even a principle binder, in the manufacture of joint cements. It can also be used in wet adhesives. The grade complies with FDA.

Elvanol™ T-25 by Kuraray is copolymer polyvinyl alcohol with high film strength, abstrasion resistance and excellent adhesion. Elvanol™ T-25 is used as a warp size for spun yarns including acetate, acrylic, cotton, wool, nylon, and polyester spun and such blends as polyester/cotton, polyester/wool and polyester/rayon.

Elvanol™ T-66 by Kuraray is polyvinyl alcohol copolymer. It provides benefits including less skinning in the size box, fewer stuck ends, laps and ends out-of lease, non-corrosive and non-toxic. Elvanol™ T-66 is used on spun yarns of cotton, polyesters or blend yarns.
