As electronic devices become thinner, smaller, and faster, silicone's outstanding physical properties allow it to excel in new applications: its high and low-temperature stability, excellent insulation, strength, elasticity and toughness, resistance to moisture, chemical stability, UV resistance, and other environmentally friendly properties, which can be bonded, protect a variety of materials.
1.3 Cost savings
Silicone has the advantages and flexibility to help fast, aseptic, and efficient production and installation. The durability of silicones reduces the cost of cleaning, maintenance, operation, and replacement of new and old electronic products. And silicone sealant adhesive has the durability and longevity that consumers demand, with better performance and stability in extreme environments, reducing wear and tear costs.
1.4 Extend the life of electronics
Silicones maintain their resistance to wear and tear even under the harshest conditions. Therefore, it has become the best component of computers, automobiles, airplanes household appliances, and other durable goods.
2. How to apply silicone?
Electronic grade silicone sealant, ( can bond with many materials, such as anodized aluminum), and coatings can be used in most consumer and commercial electronic equipment, basic components, consumer electronics, LEDs, semiconductors, circuits, connectors, capacitors, coils, transistors, and tubes, etc., the main uses are as follows.
2.1 Basic Components
Silicone has high surface resistivity, it can isolate extremely sensitive automotive electronic components. Electronic grade silicone sealant helps protect the performance of electronic components at extreme temperatures from humidity, salt corrosion, and other corrosive environments after cure. Silicone helps ensure the reliable operation of airbags, body components, brake systems, lead wire entries, ignition, fuel, and electronic assemblies in air systems and transmissions.
2.2 Consumer Electronics
Consumer electronics refers to electronic devices that can be used by consumers on a daily basis, usually with the advantages of compactness and lightweight, simple operation, and energy-saving design. According to different functions, the traditional meaning of consumer electronics products can be divided into three categories entertainment products, communication products, and home office products, and its outer edge continues to expand, white goods, baby furniture, etc. have been gradually incorporated into the category of consumer electronics, a single product function also presents a diversified trend.
Silicone can seal, bond, and pot mechanical and electronic components in home and office equipment, including power transistor rectifier heat-controlled switches. Auxiliary keyboards, keypads, and copier rollers are made of silicone - hard coatings for computers, fax machines, telephones, and the housings of home entertainment equipment are made of silicone materials.
In recent years, the consumer electronics industry has shown a sustained and stable development trend, driven by factors such as the continuous development of mobile Internet technology, the improvement of the manufacturing level of consumer electronics products, and the increase in the level of income of residents. The consumer electronics industry market size long-term upward development trend, the future with 5G, the Internet of Things, artificial intelligence, virtual reality, new displays, and other emerging technologies and the integration of consumer electronics products will accelerate product upgrading, giving rise to new product forms, and promote the consumer electronics industry to maintain the growth momentum.
The investment of consumer electronics to miniaturization, thin and light, intelligent, 5G commercial communications base station equipment, as well as the booming development of power batteries is expected to significantly boost the demand for thermally conductive materials, thermally conductive materials have a good market outlook.
Accompanied by the rapid development of the LED industry, LED chip technology and LED encapsulation technology improve the demand for LED encapsulation adhesive greatly increased, LED encapsulation adhesive products have been in the low-end areas of the full replacement of imported encapsulation adhesive, and high-end market also presents the trend of import substitution.
2.4 Household Appliances
Automatic coffee makers, digital answering machines, microwave ovens, steam irons, stereo systems, televisions, washing machines, vacuum cleaners ---- almost all the electronic components of household appliances are protected by silicone materials, and their service life has been extended. With silicone, household appliances are safer, more reliable, and require less maintenance. Silicones have also contributed to the creation of new "smart appliances" with smaller electronic systems and more advanced functions.
Silicone can be on the semiconductor ---- almost all the necessary components of electronic equipment for potting and protection. Industrial motors, locomotives, and the need for high-voltage switching power supply and other high-voltage/power applications: cell phone base stations, satellites, and radar and other high-frequency communications: aircraft engines, oil drilling, and automotive electronics, high-temperature applications (including the control of fuel efficiency and emissions sensors): the operation of these devices require semiconductors.
2.6 Electricity and Power Supply
The transmission of electricity depends on uncontaminated insulation to avoid costly and dangerous interruptions in the power supply system due to exposure to water, salt, sand, or industrial pollutants. Silicones provide high-voltage insulating coatings to protect wires, power, and communication cables. Silicone insulation ensures the safe, continuous transmission of high-energy power to underground and aboveground cables.
2.7 Circuit Boards and Electronic Modules
Silicones are critical to the assembly and protection of finished circuit boards or electronic modules in electronic applications. A variety of silicone materials, form-fitting coatings, sealants, and gels are applied to surfaces through the extruded squeeze tube to enhance the insulating and chemical resistance of the material, providing continuous protection against moisture, humidity, vibration, overheating, corrosion, and the effects of radiation. Sealants, adhesives, and primers can be easily manufactured with a variety of common materials including ceramics, glass, reactive metals, and filled plastics. This facilitates aseptic and rapid mass production of electronic systems.
High-purity silicon (made from silicone) is essential for sensitive circuits. Advances in technology have led to increased processing power, reduced size, and increasingly compact electronic modules with higher requirements for thermal stability and resistance to moisture.
