Excellent application of liquid silicone rubber in waterproofing
Liquid silicone rubber, a material with excellent flexibility and temperature resistance, has shown its unique advantages in the field of waterproofing in recent years. With its compact molecular structure and excellent physical properties, liquid silicone rubber has been widely used in various electronic products, automotive parts and other daily necessities that require waterproofing.
Waterproofing of electronic products
The application of liquid silicone rubber in waterproofing of electronic products is particularly prominent. For example, in the field of smart phones, many high-end mobile phones such as Samsung S7, Note7 and the upcoming Xiaomi MIX2 and iPhone8, etc., all use liquid silicone rubber (LSR) waterproofing technology. By adding silicone rings or silicone pads that are tightly combined with the case to potential water inlets such as the Mic port, headphone jack, side keys, Sim card tray, Micro-USB interface, etc., these mobile phones have achieved IP68 waterproof performance. Even if immersed for a long time at a depth of 2 meters, the device can remain completely waterproof and effectively prevent moisture from entering the device.
In addition, liquid silicone rubber is also widely used in electronic products such as smart watches, headphones, and wireless headphone boxes. These products also require a high degree of waterproof performance to ensure normal use in harsh environments. Through the coating and sealing of liquid silicone rubber, these electronic products can resist the erosion of rain, dust and sweat in outdoor adventures, sports and other scenes, and extend their service life.
Waterproofing of automotive parts
Liquid silicone rubber also plays an important waterproof role in automotive parts. Due to its excellent high and low temperature resistance and UV resistance, liquid silicone rubber is widely used in key parts such as car window seals, door waterproof strips, and engine compartment seals. These seals can not only effectively prevent moisture and dust from entering the car, but also keep the car quiet and comfortable.
Waterproofing of daily necessities
In addition to electronic products and automotive parts, liquid silicone rubber is also widely used in the waterproofing of various daily necessities. For example, in kitchen supplies, liquid silicone rubber is used to make anti-slip mats, sealing strips, etc. to prevent moisture and oil stains from penetrating into countertops or floors. In bathroom supplies, liquid silicone rubber is used to make shower room seals, bathtub anti-slip mats, etc. to ensure the dryness and hygiene of the bathroom.
Example display
Take a waterproof plastic watch case with liquid silicone encapsulation as an example. The red part around the case is made of liquid silicone rubber. After silicone encapsulation, the watch case has good dustproof and waterproof performance, and can maintain the normal operation of the watch in harsh environments. In addition, liquid silicone rubber is also used to make electronic cigarette shells, medical throats, medical silicone cups, pacifiers, children's water cup nozzles and other products, which also require high dustproof and waterproof performance.
