If they are bipolar they are used where the polarity gets reversed, most often in speaker systems for crossover when a paper or plastic capacitor is too large or expensive. They are also used for motor phase shifting, as in antenna rotator boxes.
Customer Service(1) If the capacitor explosion-proof valve is open when the machine is in use, or if the gas leaks, turn off the main power of the model or pull the power plug out of the socket. (2) When the explosion-proof valve of the capacitor is opened, it will eject more than 100 degrees of high temperature gas, do not close the head. If the sprayed gas
Customer ServiceWhat are the main reasons why these capacitors explode? There are several factors. Poor manufacturing processes, damage to the shell insulation, and sealing issues are common culprits.

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very thin dielectric oxide layer and enlarged an

Customer ServiceOne of the main causes of capacitor failures over life is the slow evaporation of electrolyte over time, made worse by any increased temperature. The evaporation increases ESR of capacitor, and reduces its value. This leads to localized heating inside capacitor, accelerating the degradation.
Customer ServiceA bipolar electrolytic capacitor can be made by connecting two normal electrolytic capacitors in series, anode to anode or cathode to cathode, along with diodes. As to the basic construction principles of electrolytic capacitors, there are three different types: aluminium, tantalum, and niobium capacitors.
@MattYoung They won't blow up. This is how bipolar capacitors are made. Using two electrolytic capacitors of identical value back to back is routinely used to get a non-polarized capacitor.
No, capacitor explosions are comparatively uncommon. To reduce the danger of failure, capacitors are constructed with safety measures that adhere to standards. The likelihood of a capacitor bursting is significantly decreased by following appropriate usage instructions and operating circumstances.
However, longer durations when exposed to reverse polarity will cause an electrolytic capacitor to explode. The next factor that might cause a capacitor to explode is Over voltage. A capacitor is designed to hold a certain amount of capacitance as well as withstand certain amounts of voltages and currents.

From this document: If two, same-value, aluminum electrolytic capacitors are connected in series, back-to-back with the positive terminals or the negative terminals connected, the resulting single capacitor is a non-polar capacitor with half the capacitance to either of the original pair.
