rap·id de·com·pres·sion

sudden severe expansion of gases due to a reduction in ambient pressure.

explosive decompression

In aviators or divers, decompression resulting from an extremely rapid rate of change to a much lesser pressure. This may occur if a high-altitude aircraft suddenly loses its cabin pressure or if a diver ascends rapidly. Either of these causes violent expansion of body gases.

The increase in both operating temperature and pressure of the R134A has created problems with the elastomers in both thermal stability and explosive decompression in elastomeric seal boots, orings and hose liners.
Explosive decompression typically occurs when a gas is absorbed by an o-ring while operating in high pressure; the gas is trapped within the o-ring when the system pressure drops, causing the surface of the o-ring to blister and rupture as the trapped gas expands.
With regard to rubber products, there has been a significant amount of work done in the last few years with respect to explosive decompression in products used in the oil field and with improving the life of tank treads.
It is of utmost importance that elastomer formulations be optimized for resistance to explosive decompression.
