The difference between tpe sex dolls and silicon sex dolls:

1, TPE is a variety of elastomer materials that have rubber elasticity at room temperature and can melt and flow at high temperature. Silica gel is a kind of special rubber, after crosslinking has good mechanical strength, wear resistance and high temperature resistance, it belongs to thermosetting rubber, after vulcanization and reheating will not melt, the temperature is too high will burn, the product of complete combustion is water and silica.

2, they are different in the analytical structure: silica gel is the main chain silicon-oxygen bond connected elastomer, side chain is generally methyl group, that is, CH3. TPE is a thermoplastic elastomer, including styrene, olefin and polyurethane. The main difference between the two molecular structures is that one is SI02 structure and the other is CC structure.

3, from the point of view of processing performance: silica gel needs vulcanization heating molding, TPE can be processed without vulcanization. Silicone processing molding is difficult, and TPE production and processing is simple.

4, silicone has advantages over TPE in high temperature resistance. Silica gel temperature resistance is generally between 200 degrees and 300 degrees, while TPE theory generally TPE high temperature resistance between 130-150 degrees Celsius, and then high aging cracking.

5, the price of silica gel is generally more than 30,000 pieces per ton, and the general TPE price is between 13,000-30,000, and the price of TPE is more dominant, in addition to special TPE materials, such as halogen-free flame retardant, food grade and so on.

6. From the cost point of view, silica gel waste can not be recycled, TPE waste, nozzle material, scraps and so on can be completely recycled and recycled, TPE can save more costs.
