Thermoplastic Elastomer, or TPE, as it is sometimes called, is a type of thermoplastic rubber. TPE dolls have a soft, elastic texture that feels highly lifelike, is less expensive, and is a major source for manufacturing quality sex dolls.
The most resilient substance is silicone. It can endure temperatures as high as 220 degrees. The silicone doll may produce a highly lifelike impression without being dyed. Quality-wise, silicone is superior.
