First, rubber stoppers are a common type of industrial accessory with significant advantages. They offer dustproofing, waterproofing, wear resistance, tear resistance, aging resistance, oil resistance, and ozone radiation resistance. Rubber materials come in various types, made from dozens of chemical compounds, allowing for tailored properties to meet different application needs. For industries requiring strict sealing in machinery, electronic sealing, transportation, construction, aerospace, and military industries, rubber stoppers are the most suitable choice.
Silicone stoppers share a commonality with rubber stoppers: both can be molded and vulcanized in silicone product manufacturers' vulcanizing machines. The difference lies in silicone's superior environmental friendliness, excellent high and low temperature resistance, and more pleasant tactile feel, allowing prolonged contact with human skin.
Silicone plugs, however, prioritize environmental benefits, material texture, and comfortable usability. They are thus employed in electronics, daily necessities, and small-scale waterproof/dustproof household appliances. Their raw material combines precipitated silicone with high-fineness molecular silicone rubber and silica, resulting in a soft texture and comfortable application.
