Silicone sheet is a type of thermosetting polysiloxane polymer with a highly cross-linked structure. They have the dual properties of organic resins and inorganic materials and have unique physical and chemical properties such as excellent heat resistance, cold resistance, weather resistance, electrical insulation, hydrophobicity and anti-stick release properties. These properties make silicone films widely used in many fields. The following is a specific exploration from electronics to medical fields:
一、Electronic field
Silicone sheets are widely used in the electronic field, which is particularly evident in the following aspects:
1. Sealing of integrated circuits: Silicone sheets have excellent heat resistance and electrical insulation, making them an ideal sealing material for integrated circuits.
2. IC packaging: Silicone films can be used for IC packaging to protect ICs from interference and damage from the external environment.
3. Electronic component packaging: Silicone films can also be used to package electronic components such as capacitors and transformers to improve the stability and reliability of electronic products.
4. LED packaging: Silicone films play an important role in LED packaging, which can protect LED chips from moisture, oxidation and other adverse effects.
5. High voltage cable protection and high voltage electrical insulation: The high insulation performance of silicone sheeting makes it the preferred material for high-voltage cable protection and high-voltage electrical insulation.
二、Automotive field.
Silicone sheets are also widely used in the automotive field, mainly including:
1. Spark plug insulator: Silicone sheets have good insulation and heat resistance and can be used for the insulator part of spark plugs.
2. Electronic igniter insulation material: Silicone sheets can be used as insulating materials for electronic igniters to ensure the normal operation of igniters.
3. Oxygen sensor waterproofing material: Silicone sheets have excellent waterproofing properties and can be used for waterproof sealing of oxygen sensors.
4. Antenna joint sealing material: Silicone sheet can also be used to seal antenna joint to prevent moisture and dust from entering the joint.
三、Medical field.
Silicone sheets are also widely used in the medical field, especially in the following aspects:
1. Manufacture of medical devices: Silicone sheets can be used to manufacture various medical devices, such as artificial heart valves, medical silicone rubber sleeves, artificial lung oxygenators, etc. These medical devices require good biocompatibility, corrosion resistance and biostability, and silicone sheet is an ideal material to meet these requirements.
2. Coating of medical devices: Silicone films can also be used to coat medical devices such as surgical instruments, dental instruments, sutures, etc. The coated medical devices have better wear resistance, antibacterial and biocompatibility.
3. Medical adhesives: Silicone films can be used as adhesives for biomedical applications such as artificial joints, bone fixation devices, etc. The adhesive has good biocompatibility, moisture resistance and high and low temperature resistance.
4. Medical dressings: Silicone films can be used to make various medical dressings, such as wound dressings, burn dressings, wound care films, etc. The dressings have good air permeability and moisture resistance, which promotes wound healing.
四、Other fields
In addition to electronics, automotive and medical fields, silicone films are also widely used in other fields:
1. Building materials: Silicone sheets can be used to seal and waterproof buildings, such as tempered glass, building curtain walls, roof protection, bathroom waterproofing, floor sealing, etc.
2. Clothing industry: Silicone sheets can be used in the garment industry for coating and waterproofing various fibre materials, such as waterproof clothing, ski suits, raincoats, swimsuits, etc.
3. Manufacture of kitchen utensils: Kitchen utensils made of silicone sheets have good high temperature resistance and non-stick properties, and are easy to clean.
4. Aerospace: Silicone films are also used in aerospace applications, such as seals and insulation materials for aircraft and spacecraft.
In summary, the application fields of silicone films are very wide, covering electronics, automobiles, medical care, construction, clothing, kitchen utensil manufacturing, aerospace and other fields. With the advancement of science and technology and the continuous improvement of people’s material performance requirements, the application prospects of silicone sheeting will become even broader.
