Secret of smart Bracelet material selection

As the saying goes: steel watch with steel belt, gold watch with gold belt, what should smart watch and smart Bracelet match? In recent years, the market demand for smart wear has been expanding. According to the latest data report of CCS insights, the shipment of smart watches and smart bracelets in 2020 was 115 million and 78 million respectively. The considerable market prospect makes many domestic electronic manufacturers join the intelligent wearable device industry one after another. Watch straps of various materials such as silica gel, TPU, TPE, fluororubber and other materials emerge one after another. While they have outstanding characteristics, they also have the following disadvantages:






one






Silica gel material: it needs to be sprayed. The sprayed surface is easy to be damaged, affecting the touch, easy to get stained with ash, short service cycle, low tear strength, long production cycle, and waste can not be recycled;






two






TPU material: the material has strong plasticity (high hardness, low temperature hardening), easy fracture, poor UV resistance, poor yellowing resistance, difficult demoulding, long forming cycle, etc;






three






TPE material: poor pollution resistance, rapid decline of physical properties with temperature rise, easy precipitation after oil filling, increase of plastic deformation, etc;






four






Fluororubber: the surface spraying process is difficult to operate, which affects the hand feel of the substrate, and the coating contains organic solvent. The coating is easy to wear and fall off, and the pollution resistance deteriorates with the damage of the coating, which is expensive and heavy;


Silico Si TPV takes into account performance, efficiency and comprehensive cost. It has the advantages of high efficiency, high quality and high cost performance. It effectively overcomes the defects of mainstream materials in actual production and use, and is superior to mainstream materials in the market in terms of high body feeling, pollution resistance and high strength.






Delicate and soft skin feel






As the name suggests, smart wear is an intelligent product that will have long-term direct contact with the human body. The comfortable touch of watch belt and bracelet is very important in the long-term wearing process. Delicacy, softness and skin affinity are the first concerns of material selection. Si TPV has excellent delicate, soft and skin friendly touch without secondary treatment, so as to avoid the complex processing procedures caused by coating and the impact of coating falling off on the touch.






Dirt resistant and easy to clean






Smart watches and bracelets are not as good as mechanical watches. Metals are used as watchbands. Stains are often adhered in the long-term wearing process, which is difficult to wipe clean, thus affecting the beauty and service life. Si TPV has good pollution resistance, easy to clean, and there is no risk of adhesion during long-term use. The following figure shows the oil resistance pen writing test of silico Si TPV product. Write the left and right short vertical with an oil pen respectively, and wipe it with daily toilet paper dipped in alcohol after placing it at room temperature of 25 ℃ for 10min and 30min. It can be seen that Si TPV has great advantages in pollution resistance. The video shows the pollution resistance test of Si TPV. The test method is to drop chili oil on the Si TPV sample plate and wash it with clean water after standing for 30min.
