TPE (ThermoplasticElastomer) is a thermoplastic elastomer with high elasticity, high strength, high resilience of rubber, but also has the characteristics of injection molding process. With environmental protection, non-toxic safety, a wide range of hardness, excellent coloring, soft touch, weather resistance, fatigue resistance and temperature resistance, superior processing performance, without vulcanization, can be recycled to reduce costs, both secondary injection molding, and PP, PE, PC, PS, ABS and other base materials wrapped bonding, can also be molded separately, the material can be recycled, and cost savings, and than TPU Cheap, and in line with the medical industry ISO-10993 test.

Smart bracelet, its wristband is an important component of the accessories. The wristband part, direct contact with the wrist, its material surface feel, as well as with the skin's biocompatibility (no skin sensitization, etc.), etc., are aspects to consider.

　　In addition, the wristband design surface texture, style and color, etc., can show the personality and grade of the smart bracelet. Therefore, the choice of smart bracelet wristband material, it is so important. So, the

　　Smart bracelet wristband material

　　1. silicone: silicone is the top environmentally friendly material. Silicone has excellent elasticity and a smooth touch, which is a material that gives consumers complete peace of mind. Processing method is oil pressure molding, the material can not be recycled. The cost is not cheap. Identification of silicone: burning will produce a white powder with a bright flame.

　　2.TPU:TPU material has excellent elasticity and can be injection bonded with another hard plastic PC of the bracelet. The cost is also relatively cheap, and the material can be recycled. The disadvantage is that the soft touch aspect is not ideal. Hardness selection, usually above 70A, softer hardness of TPU, the material required is very high cost. Identify TPU: burning as a yellow flame, there is a slight sound of zipping, ammonia odor.

　　3. TPE: based on SEBS base elastomeric material. This type of soft material is also thermoplastic, can be injection molding. The advantage of the material is comfortable and soft to the touch, with excellent elasticity, can simulate the effect of soft and smooth skin. It also provides excellent bonding to PC plastics.

　　In terms of softness and hardness, a wide range of Shore30~90A is available. The material can be recycled, and the cost is not cheaper than TPU, and may even be more expensive. The special blending system is used, which makes the material not easy to stick to dust and good stain resistance.

　　TPE/TPR is a non-toxic, odorless and safe material, which has no allergenic effect on human skin. It complies with ISO-10993 test in medical industry. Putting aside cost considerations, TPE is the more ideal wristband material, but also in the high-grade smart bracelet wristband material alternative. Identification of TPE: burning for a special aromatic smell, the flame is yellow on the blue.
