The Principle of Liquid Silicone Rubber Vulcanization Has a Wide Range of Applications
These applications are primarily based on the excellent properties formed during the vulcanization process of liquid silicone rubber, such as high transparency, good thermal stability, aging resistance, chemical resistance, and strong adhesion. Below are some of the major application areas:
1. Construction Industry
Sealants: Liquid silicone rubber is commonly used as a sealant in the construction industry, such as for highway joints, panel joints in high-rise buildings, curtain walls, and interior wall joints. It is also used for filling gaps around kitchen tiles and sealing around bathtubs, sinks, and toilets. The solid material formed after vulcanization exhibits excellent weather resistance and aging resistance, ensuring long-term sealing effectiveness.
2. Electronics and Electrical Industry
Keypads and Insulating Materials: In the electronics and electrical industry, liquid silicone rubber is used after vulcanization to manufacture keypads for devices such as computers, telephones, and fax machines, as well as insulating materials like insulators, TV anode caps, and high-voltage protective covers. These applications require materials with good fatigue resistance, high-temperature resistance, ozone resistance, and electrical insulation.
3. Automotive Industry
Sealing and Bonding Materials: Liquid silicone rubber is widely used in the automotive industry for sealing and bonding components such as ignition wires, spark plug covers, heater and radiator hoses, muffler liners, fuel pumps, and intake valves. The material formed after vulcanization can withstand high temperatures, resist fatigue, and has excellent adhesion, ensuring the reliability and durability of automotive components.
4. Medical and Healthcare
Medical Supplies: In the medical and healthcare field, liquid silicone rubber is used for applications such as baby bottle nipples, various medical tubes, catheters, cosmetic repair materials, and artificial organs. These applications require materials that are non-toxic, physiologically inert, and resistant to aging. The vulcanized liquid silicone rubber meets these requirements, ensuring the safety and effectiveness of medical supplies.
5. Cable Industry
Cable Insulation: After vulcanization, liquid silicone rubber can be used to manufacture insulation layers for power cables, marine cables, and aviation wires. Its excellent electrical insulation, weather resistance, and moisture resistance enable cables to maintain stable performance in harsh environments.
6. Aerospace Industry
Sealing Gaskets and Shock-Absorbing Layers: In the aerospace industry, liquid silicone rubber is used after vulcanization to manufacture various hoses, oxygen masks, sealing gaskets, and shock-absorbing layers for aircraft and spacecraft. These applications require materials with high and low-temperature resistance, ozone resistance, fatigue resistance, and radiation resistance. The vulcanized liquid silicone rubber meets these stringent requirements.
7. Other Fields
Breathable Membranes and Sealing Adhesives: Liquid silicone rubber can also be used to produce breathable membranes and sealing adhesives for solar photovoltaic panels, wind turbines, and other equipment. Its selective breathability and resistance to water vapor make these applications possible.
With the continuous advancement of technology and the expansion of application areas, the prospects for liquid silicone rubber applications will become even broader.
