Thermoplastic Elastomer – Similar in makeup to TPR, but generally this material is opaquely pigmented and is used for more lifelike and matte finish materials that simulate flesh in masturbators, strokers and some penis pump insert sleeves. More forgiving and lifelike than TPR, this material may need treatment using Care powder (primarily cornstarch). Cyberskin and Fantaflesh are proprietary formula examples of this compound.
