PassionSkin is a trademarked name for a softened variety of Thermoplastic Elastomer (TPE). As its name suggests, PassionSkin is used to make a variety of sex toys including vibrators and dildos.
PassionSkin has a greater molecular density than traditional Thermoplastic Elastomer. This makes the material more flexible than many other Thermoplastic Elastomers, and also more resilient.
PassionSkin is also known as SensaFirm, Trueskin, PleasureSkin, Techno-Skin, and Private Touch.
