From 6 aspects, analyze the differences between TPE and silicone solid dolls from multiple perspectives
Introduction and Application of TPE and Organosilicon MaterialsSilicone has the advantage of being safe and non-toxic, as it is insoluble in water and any solvents. Non toxic and odorless, with good chemical stability, it does not react with any substance except for strong bases and some acids. TPE has high adsorption performance, good stability, and stable chemical properties. Two materials are widely used in adult products, such as physical dolls and sex toys.
TPE is a thermoplastic elastomer that is environmentally friendly, non-toxic, easy to color, smooth and soft to the touch, with a hardness range of 0A-120A. It is easy to process and shape, does not require vulcanization treatment, and can be recycled and reused to reduce costs. In addition, it can be coated with plastic materials such as PP, PE, PC, PS, ABS (over plastic), or molded separately.
What is the difference between TPE and silicone solid dolls?
Elastic difference
TPE is a general term for various elastic materials that exhibit rubber elasticity at room temperature and melt flowability at high temperatures. Silicone is a special type of rubber that has good mechanical strength, wear resistance, and high temperature resistance after cross-linking. It is a thermosetting rubber that does not melt after vulcanization. If the temperature is too high, it will burn, and the products of complete combustion are water and silicon. Therefore, the elasticity of dolls made from each of them is different.
Differences in chemical structure
Silicone is the main chain of oxygen bonded elastomers, and the side chain is generally methyl, i.e. CH3. TPE is a thermoplastic elastomer containing styrene, olefins, and polyurethane. The main difference between these two molecular structures is the SI02 structure and the CC structure. As you can see, silicone dolls are more durable than TPE physical dolls.
Differences in processing performance
Silicone requires vulcanization and thermoforming, while TPE can be processed without vulcanization. It is difficult to form in the processing of silicone, while the production and processing of TPE is relatively simple.
Difference in high temperature resistance
In terms of high temperature resistance, silicone has advantages over TPE. The heat resistance of silicone is usually between 200 and 300 degrees Celsius, while the temperature tolerance of TPE is generally between 130-150 degrees Celsius.
Cost difference
The price of silicone is generally above 30000 yuan/ton, while the average price of TPE is between 10000-30000 yuan/ton. TPE has a price advantage, except for special TPE materials such as halogen-free flame retardants, food grade, etc. So you can buy physical dolls at the most favorable price.
Environmental Differences
Silicone waste cannot be recycled, while TPE waste, nozzle materials, decorative parts, etc. can be completely recycled and reused. Obviously, TPE physical dolls are more environmentally friendly.
Which is more suitable for producing physical dolls, TPE or silicone?
Both have their own advantages, but compared to silicone, TPE has lower costs in terms of process capability, recycling, and cost. With the increasing types and applications of TPE, TPE is the preferred material to replace silicone! Therefore, compared to silicone, TPE is more suitable for producing physical dolls.
