There are plastics (like Polyamide) which are brittle in the dry condition (water proportion < 0.2 %).
The plastic part gets more elastic when water up to 3.5 % is absorpt.
The storage and water absorption in moistured athmosphere or in a water bath until the weight is consistent is called conditioning.
The conditioning occurs by diffusion and may take several days.
The process is reversible.

Conditioning in Injection Molding

A polyamide is elastic after conditioning.
