In recent years, wearable devices, such as smart bracelets, children's positioning smart bracelets, smart watches, etc. are all the rage, and many of these wearable products, many of which use silicone as a raw material. But do you know that TPE is the ideal raw material for smart bracelet wristbands! Next Plastic Bo give you an analysis.

　　The advantages of silicone:

　　1, excellent resilience, comfortable and smooth to the touch.

　　2, environmental protection and non-toxic, no sensitization of the skin, in line with the ISO-10993 medical certification.

　　3, hardness optional, can provide hardness 10 ~ 90A different materials to adapt to different product requirements.

　　Silicone shortcomings:

　　1, need oil pressure molding, production cycle is long, productivity is not high;.

　　2, secondary materials (such as corners, waste materials) can not be recycled.

　　It is worth noting that the excellent characteristics of thermoplastic elastomer TPE, so that it began to gradually win the attention of the field of smart wearable and favor of the eyes. TPE become the ideal raw material for smart bracelet wristbands:

　　TPE relative to silicone: fast production, high production efficiency; corners of the waste material can be recycled over and over again.

　　TPE relative to TPU: has a broader range of hardness options (0 ~ 95A), TPU hardness needs to be above 60A. And TPE relative to TPU, has a softer touch close to the skin.

　　TPE blending system has better compatibility (blending modification), easy to adjust the characteristics of the material. At present, more adapted to the smart wearable (bracelets, wristbands, watch bands) industry TPE has been developed and matured. This kind of TPE material has excellent elasticity closer to silicone, and the surface is softer and smoother. In addition, the surface is not easy to stick to the dust, excellent antistatic properties, has excellent anti-fouling properties. The choice of other mixing systems, but also fully take into account the environmental safety (skin safety and non-allergenic)

　　The characteristics and hardness of TPE materials used for different wearable devices are different, and the usual hardness range is 50~80A. As mentioned above, the TPE blending system has good compatibility, so different grades of TPE can be provided, which can be used for smart bracelet wristbands (composite molding with PC, PC+ABS materials), for handicrafts bracelets, and for wristbands with the function of USB flash drives, and for watch band (can be compound molding with ABS and other plastics).

　　In the last year or two, smart wearable devices have been a fashion-leading field. Such an industry in the spotlight will naturally lead to a variety of grades (or high imitation or cottage) of smart wearable products competing to meet the needs of different consumer markets. Considering the characteristics and cost of TPE materials, TPE can be positioned as the preferred raw material for mid- to high-end wristbands.
