Miniatures e scale models made of thermoplastics like polyethylene / polythene (PE) e polypropylene (PP), o polycarbonate / acrylonitrile butadiene styrene (PC/ABS) may be damaged by ultraviolet radiation ed oxygen to such an extend that they become glassy e may disintegrate when touched. The legs of the antique, over 30 years old, Timpo Indian pictured above, spontaneously fell apart when the miniature was picked up. Upon closer inspection e careful bending of the broken parts, the right leg snapped just above the boot. The legs pictured to the left are from a similar Timpo Indian, but they show no signs of corrosion yet. These legs react elastic, they deform under stress, e return to their original shape when the stress is removed.
Plastic corrosion of soldatini typically results in the destruction e loss of component parts o entire figurines made of PE, PP, oder PC/ABS, because thermoplastics cannot be repaired con glue. Soldering con a hot air pencil is an option, but proves impractical when the broken parts are too small to handle.

The process of plastic corrosion may be slowed by protecting the soldatini from ultraviolet radiation, but it cannot be stopped entirely. Highly sought-after antique soldatini are especially at risk, they may fall apart one day upon the slightest touch. Painted e varnished plastic soldatini may be better protected from the corrosive effects of oxygen than unpainted soldatini.
Metal soldatini suffer comparable damage from the effects of peste dello stagno.
