Desiccants are critical to airbag safety and reliability because they prevent moisture from accumulating inside the airbag inflator, preventing a potentially fatal deployment.
In 2016, Takata was ordered to recall millions of airbags because the National Highway Traffic Safety Administration found that moisture exposure and temperature cycling degraded the propellant, potentially causing an inflator explosion. Initially the industry responded by pouring loose molecular sieve beads into vulnerable inflators, preventing moisture-driven degradation – but also creating a risk of bead escape in cars and bead spills on factory floors.
With PolySorb, airbag inflator manufacturers are able to install one solid injection molded component instead of loose desiccant beads, simplifying installation and eliminating bead handling challenges.
