Publish Time: 2025-07-16
In the warm home life, those seemingly inconspicuous little things often play a vital role, and silicone gaskets are one of them. It is like a "behind-the-scenes hero" who silently guards. Although it is not eye-catching, it relies on its unique performance to escort the quality and convenience of home life, and can be called the "invisible guardian" in the home.1. Wide range of scenarios, all-round protection of homeSilicone gaskets are widely used in home and are almost everywhere.
Kitchen: Sealing Guardian of Cooking UtensilsIn the kitchen space, silicone gaskets exist in the form of dynamic sealing in cooking utensils such as rice cookers and pressure cookers. When the pressure in the pot reaches 0.8MPa, its adjustable Shore hardness of 30-70A ensures that the sealing surface is evenly stressed, and with the wire diameter accuracy of 0.1-0.3mm, zero leakage sealing is achieved. Experimental data show that after high-quality silicone gaskets work continuously for 2000 hours in a 200℃ oil steam environment, the compression permanent deformation rate is still less than 15%, far exceeding that of traditional rubber materials. At the same time, it is also a small seal guard at the connection between the sink and the countertop. With its soft and elastic characteristics, it fits tightly between the two, effectively preventing water leakage, avoiding moisture damage to the countertop, and keeping the kitchen dry and tidy.Bathroom: A line of defense to isolate stains and odorsIn the bathroom, silicone gaskets also play an important role. If there is no silicone gasket to seal the gap between the bottom of the toilet and the ground, sewage and odors can easily seep out of the gap, polluting the indoor air and affecting the living experience. The sealing performance of the silicone gasket is like a solid line of defense, which firmly blocks sewage and odors and keeps the bathroom fresh and hygienic. The silicone gasket at the shower door frame forms a non-contact seal through surface microstructure treatment. Its 0.02-0.05mm micro-convex structure can form an effective seal under a pressure of 5N, which increases the water saving rate by 40% compared with traditional wool strip seals. In a temperature change environment of -20℃ to 80℃, the elastic recovery rate remains above 98%, effectively solving the problem of sealing failure in winter.
Home appliances: key components to ensure operationSilicone gaskets are also indispensable in various home appliances. The silicone gasket in the refrigerator door seal adopts a dual-hardness composite structure, with a contact surface hardness of 40A to ensure sealing, and a support layer hardness of 70A to maintain deformation stability. This design reduces the daily power consumption of the refrigerator by 0.3kWh, and the annual electricity saving is equivalent to reducing 12kg of carbon dioxide emissions. Silicone gaskets are also found at the water inlets and drains of home appliances such as washing machines and dishwashers. The silicone gasket at the water inlet valve of the washing machine has been treated at the nanoscale surface to increase the chloride ion tolerance concentration to 200ppm, and the service life is extended to 3 times that of traditional materials, ensuring smooth water flow and no leakage, ensuring the normal operation of home appliances.2.
