PVC-based gas generant for hybrid gas generators

摘要

The amount of particulate matter that is forced into the passenger compartment of an automobile by the deployment of an air bag as it protects the lives of occupants is reduced by improving the filterability of the combustion products of a composition for generating gas to inflate the bag. The filterability is improved by adding a nucleating agent for alkali metal halide vapors formed during said combustion. Silica, alumina, and graphite are representative of the nucleating agents.
