Bayer MaterialScience Debuts Impranil® PU Dispersions For Protective Gloves

Germany-based polymer manufacturer Bayer MaterialScience AG has introduced Impranil® brand
polyurethane (PU) dispersions for coating the textile substrate of lined gloves. Protective gloves
made with the dispersions contain no plasticizers or allergenic proteins; and are strong and
abrasion-resistant, yet comfortable, the company reports.

Gloves incorporating Impranil dispersions may be produced on conventional molds in dip
processes, which require lower temperatures than those necessary for producing gloves made using
conventional materials such as latex and nitrile, according to Rolf Irnich, textile coatings
specialist, Bayer MaterialScience.

“The grippiness of the glove surface can be precisely adjusted — from sticky to dry and
flexible — by the choice of the PU dispersion and the formulation,” Irnich said. The amount of grip
also may be adjusted on fabric-free disposable gloves. Gloves coated using Impranil XP 2772 offer
good resistance to alcohol-based cleaning agents and solvents, the company reports, and the coating
is odor-free.
