Abstract:
Rollers for high speed printers and paper handling devices are fabricated by reacting polymeric diphenylmethane diisocyanate with a polyester polyol and/or polyester polyamine and an optional extender, together with a metal salt, a catalyst, and one or more other optional additives, including a liquid conductive additive. The resulting rollers provide a hardness as low as 15 A on cube, a resistivity as low as 5E4 Ω·cm, a compression set as low as 0.5% at room temperature and as low as 3% at 157° F., and low tackiness as low as 13 g/cm of adhesion force.
