Summer bracelet wristbands to choose what material breathable good smart bracelet material to choose which is good
1, TPE: ThermoplasticElastomer abbreviation, that is, thermoplastic elastomers, is a class of plastic plastic and rubber elasticity of the special functional materials. Burning has a better smell of aromatic flavor, TPE hardness can do 0A-95A.
2, TPU: Thermoplasticpolyurethanes abbreviation, that is, thermoplastic polyurethane elastomer rubber, is a kind of high wear-resistant, impact resistance, vibration damping cold resistance outstanding a kind of material. TPU is characterized by high strength, wear resistance, burning has a slight irritating ammonia odor, there is a slight explosion of nuisance sound. The minimum hardness is above 70A.
3, Silicone: Silicone rubber (Silicondioxide), is a highly active adsorbent material, is an amorphous substance. Insoluble in water and any solvent, non-toxic and odorless. Characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength and so on.
Smart bracelet TPE material and silicone, TPU what is the difference
tpe is a rubber with high elasticity, high strength, high resilience, but also has the characteristics of injection molding processing materials. With environmental protection, non-toxic safety, wide range of applications, excellent coloring, soft touch, weather resistance, fatigue resistance and temperature resistance, superior processing performance, without vulcanization, can be recycled to reduce costs, both the second injection molding;
TPU is made of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI), such as diisocyanate molecules and macromolecular polyol, TPU is a polymer material made by polymerizing diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI), large polyol molecules, and low molecule polyol molecules (chain extender)**** with the reaction. Its molecular structure is composed of rigid blocks obtained by the reaction of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and chain extender, and flexible chains obtained by the reaction of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and macromolecular polyols in an alternating manner.TPU is characterized by excellent high tensile strength, high pulling force, toughness, and aging resistance, and is a mature environmentally friendly material. TPU has excellent high tension, high tensile strength, toughness and aging resistance, and is a mature environmentally friendly material. At present, TPU has been widely used in health care, electronic and electrical appliances, industry and sports, etc., with other plastic materials can not be compared to the high strength, good toughness, wear-resistant, cold-resistant, oil-resistant, water-resistant, aging-resistant, weather-resistant and other characteristics, at the same time, he has a high degree of waterproofness and moisture permeability, windbreaks, cold, anti-bacterial, mildew, warmth, UV resistance and energy release and many other excellent features;
Silicone is a highly active silica gel. >Silica gel is a highly active adsorbent material, is an amorphous substance, its chemical molecular formula is mSiO2-nH2O; in addition to strong alkali, hydrofluoric acid does not react with any substance, insoluble in water and any solvent, non-toxic, tasteless, stable chemical properties. Various models of silica gel due to its different manufacturing methods and the formation of different microporous structure. The chemical composition and physical structure of silica gel, it has many other similar materials difficult to replace the characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength and so on.
What kind of material is the smart bracelet made of now?
The main body of the smart bracelet is generally made of medical rubber and memory rubber. Depends on what type of group you are targeting. In the case of children, the material requirements are non-toxic and harmless. Can be edible grade!
Introduction: smart wear from the previous only appeared in the world of science fiction, to now enter the common people's home. Smart bracelet application market is now also into the white-hot era of spelling connotation, the partners have also changed from the initial taste of fresh to the use of merit, smart bracelet the more additional features the more the partners can be seen. Cost-effective and closely follow the market bracelet will become the protagonist of the market, how to choose the bracelet suitable for their own has become the heart of the urgent requirements of many small partners.
How to choose the right smart bracelet for you
One, pick the material of the smart bracelet. Nowadays, there are about 4 kinds of materials for smart bracelets:
1, Silicone. Silicone is the top environmentally friendly material. Silicone has excellent elasticity and a smooth touch, making it a completely reassuring material for consumers.
2, TPE/TPR. This is actually an elastomer material based on SEBS foundation. This kind of soft material is also thermoplastic, can be used for injection molding.TPE, TPR is the more ideal wrist wristband material, is also the middle and high grade smart bracelet wristband material alternative.
3, TPU or PU. both materials belong to polyurethane, the difference is that one is thermoplastic (TPU), a casting type (PU). PU leather has a good soft touch, and there is no smell, can be used as a qualified artificial leather bracelet wristband material.
4, soft PVC. soft PVC feel soft, color matching color bright, and low price. But PVC material has a large odor.
High-grade smart bracelets generally use silicone, the rest in descending order.
Next, choose according to the function. Now the functions of the smart bracelet are: monitoring sleep quality, smart alarm clock wake up, you can view the amount of exercise in real time through the cell phone application, monitoring the effect of walking and running, but also through the cloud to identify more sports. In addition to this, it is also enough to automatically determine whether to enter the sleep state, record deep sleep and light sleep and summarize the sleep time, to help users monitor their own sleep quality. Some smart bracelets, to a certain extent, can also be used as a cell phone, so choose according to their own needs.
Two, choose a more assured brand. Domestic can produce smart bracelets . Most of the companies occupy a certain position in the field of smart phones, because the smart bracelet and smart phone production configuration has a similarity, so most of the cell phone companies will desperately squeeze into the nascent market. Therefore, to pick a good smart bracelet, you can first pick a cell phone company with a good reputation, and then take a look at their matching smart bracelets. There are just a few big foreign brands, so go to Baidu and search for the ranked ones in a flash.
Three, pick a long cruise time, more durable. The main role of the smart bracelet is to record data, and then their own to analyze their own physical condition, therefore, the battery applies to a long time as well as the durability of the smart bracelet in the heart of the small partners of the status of the smart bracelet. Try, if a smart bracelet needs you to keep charging, and the use of the process all of a sudden there is no electricity or the use of the process of heating is more powerful, then your user experience must be uncomfortable.
Four, the appearance of fashionable. The appearance of the smart bracelet design should focus on the inclusion of fashion elements, and must focus on simplicity and generosity. The bracelet has a simple design style, which can make the whole smart bracelet look high-end, and secondly, the heart will be more comfortable during the use.
