Morse code is a time-interrupt signal code, which expresses diffecheap custom keychainsrent letters, numbers and punctuation symbols in different order. It was invented in 1837 by American Samuel Morse Morse code, an early form of digital communication, which played an important role in the early radio and was known to every radio communicator. As a result of advances in communication technology, Morse codes were discontinued in 1999. We can customize bracelet with the morse code on. The band can be solid, swirled, segmented, glowing and UV transfer. Morse code can be printed, colorfilled, embossed printed. Regular sizes of a rubber bracelet are 6”(150mm) for toddler, 7”(180mm) for youth, 8”(202mm) for adult in circumference and 1/4”(6mm), 1/2”(12mm), 3/4”(19mm), 1”(25mm) in width. We make it all together 2mm thickness. rphous material. Silica gel is a kind of amorphous silicon dioxide, mainly composed of silica. Its chemical property is stable, and it does not burn. Chemical formula is xSiO2?yH2O. Silica gel contains organic silica gel and inorganic silica gel. Inorganic silica gel is a highly active adsorption material. It is usually prepared by reaction of sodium silicate and sulfuric acid, and a series of post-processing processes such as aging and acid bubble. Household use desiccant, humidity regulator, deodorizer belocheap custom keychainsngs to inorganic silica gel.Organic silica gel is an organosilicon compound. It refers to a compound containing Si-C bond and at least one organic group, which is directly linked to silicon atoms. It is mainly divided into four categories: silicone rubber, silicone resin, silicone oil and silane coupling agent. There are 4 types of silicone products, moulded silicone products, extruded silica gel products, liquid silica gel products and special silicone products. Silicone rubber is one of organic silica gel and it is one of the moulded silicone products Temperature resistance, weatherability, electrical insulation performance, Physiological inertia, Low surface tension and low surface energy are the outstanding characteristics of organic silica gel. The one we use to make bracelet is named polysiloxanes di-Me Me vinyl vinyl group-terminated chemically. We add curing agent to the soft original silicone rubber and mix them evenly, then put it to molding machine with high temperature of about 200℃, a few seconds later the silicone rubber gets solidified. Here comes the silicone bracelet with custom logo by mould. Characteristic of the silicone rubber stay same on the process but it get more strengthened. lled) bracelet.

Usually the wristband width need at least 15mm so that the code is clear enough to be scaned. When you scan the code with a phone, the detail of patient name, address, status will show up. It is a good help for doctor and patient to know the treatment. All the medical bracelets should made from 100% silicone. If the bracelet is embeded with a chip, it will note down the information of exercise, heart beat and sleeping. Then trafer it to the phone app. It contribute to health care. It is for special needs like Alzheimer, Dementia etc. Order over than 100 get 100pcs wristbands free & 10pcs keychains free. Order less than 100 get 50pcs wristbands free & 5 pcs keychains free.
