CyberSilicone is a trademarked name used for some toys made a blend of Thermoplastic Rubber (TPR) and silicone. The material is soft enough to allow it to be used in the creation of a variety of sex toys including dildos, vibrators, and butt plugs. While silicone is a nonporous material, CyberSilicone is porous due to the inclusion of TPR.
More About CyberSilicone
Manufacturers claim that CyberSilicone toys are hypoallergenic and free of phthalates, but that claim is questionable. CyberSilicone falls under the category of "mystery materials." Since the sex toy industry is unregulated, there is no way to be sure about the safety of material blends.
