Aluminum capacitor sleeve refers to the plastic packaging wrapped in the capacitor body, and the commonly used materials are mainly PVC and PET, which at first glance are not much different.
In fact, PET sleeve is non-toxic and environmentally friendly, and will not cause harm to the human body or the environment. According to the global REACH standard, the content of phthalates (plasticizers) and organotin compounds (stabilizers) is limited, but these substances are ubiquitous in PVC hoses. Therefore, most suppliers of aluminum capacitors tend to replace PVC bushings with bushings made of other materials.
For example, some Rubycon aluminum capacitors will have the suffix "EFC" at the end of the part number, which means that the PET sleeve is wrapped around the outside of the aluminum capacitor body
