Able to be broken apart, separated into pieces, or decomposed.
From disintegrate + -able (capable of being). The root integrate comes from Latin integrare 'to make whole,' so disintegrable means 'capable of being made not whole.'
Scientists study which plastics are disintegrable versus which will survive thousands of years—this distinction is literally shaping environmental policy. Biodegradable is common, but disintegrable emphasizes breaking apart physically, not just decomposing chemically.
