Among mammals, the hair (including wool), horns, nails, claws, corns, and hooves, which are made primarily of α-keratins
Among reptiles, the scales, claws, and, in the chelonians, such as tortoise, turtle, terrapin, the shells, which are made primarily of β-keratins
Among birds, the feathers, beaks, and claws, which are made primarily of β-keratins

Yes, a rubber ball is typically made from synthetic polymers such as polybutadiene or polyisoprene. These polymers give the rubber its elasticity and bounce.
