Analysis of TPE and Silicone sex doll torsos
Introduction and Applications of TPE and Silicone Material
Silicone has the advantages of safety and non-toxicity. It is insoluble in water and all solvents. It is non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. A TPE doll has high adsorption performance, good stability, and stable chemical properties. It has been widely used in adult products such as silicone sex doll torsos and food products.
TPE is a kind of thermoplastic elastomer, which is environmentally friendly, non-toxic, easy to color, smooth and soft to the touch, and has a hardness range of 0A-120A. It is easy to process and mold, does not require vulcanization processing, and can be recycled and used to reduce costs. In addition, it can be coated (overmolded) with PP, PE, PC, PS, ABS and other plastic materials, or molded separately.
What are the differences between TPE and silicone real doll torsos?
Difference in elasticity
TPE is a general term for a variety of elastomer materials that are rubber elastic at room temperature and melt at high temperatures. Silicone is a kind of special rubber. It has good mechanical strength, wear resistance and high temperature resistance after cross-linking. It is a thermosetting rubber and will not melt after vulcanization. If the temperature is too high, it will burn. The product of complete combustion is water and silicon. So the dolls made from it have different elasticity.
Difference in analytical structure
Silicon is the backbone of the oxygen-bonded elastomer, and the side chain is generally methyl, which refers to CH3. TPE is a thermoplastic elastomer containing styrenes, olefins and polyurethanes. The main difference between the two molecular structures is the SI02 structure and the CC structure. As you can see, the silicone doll is more durable than the TPE sex doll torso.
Difference in processing performance
Silicone needs to be vulcanized and deep-drawn, TPE can be processed without vulcanization. It is difficult to mold when processing silica gel, and the production and processing of TPE is relatively simple.
Difference in high temperature resistance
Silicone has an advantage over TPE in terms of high temperature resistance. The temperature resistance of silica gel is generally between 200 and 300 degrees, while TPE theory is generally between TPE and high temperature of 130-150 degrees Celsius.
Cost difference
The price of silica gel is generally more than $2,000, while the average TPE price is between $100 and $1000. The price of TPE is more dominant, except for special TPE materials, such as halogen-free flame retardant, food grade and so on. So you can buy real doll torsos at the best price.
Difference in environmentally friendly
Silicone waste cannot be recycled, TPE waste, nozzle material, trim, etc. can be completely recycled and reused. Obviously, the TPE sex doll torsos are more environmentally friendly.
TPE and silicone, which is more suitable for making sex doll torsos?
Both have their own advantages, but TPE costs less than silicone in terms of processability, recycling and cost. As TPE is used more and more in type and application, TPE is the preferred material to replace silicone! While TPE is compared to silicone, TPE is definitely more suitable for making sex doll torsos.
