Silicone sealing ring

Silicone sealing ring is mainly used for waterproof sealing and preservation of daily necessities such as crisper, rice cooker, water dispenser, lunch box, heat preservation box, incubator, water cup, oven, magnetized cup, coffee pot and so on.


It can be used for a long time in the temperature range of -60 degrees to +200 degrees.

1. It has excellent sealing performance and is waterproof.
2. The preservation effect is good, completely non-toxic and tasteless.
3. It can be heated under high temperature, no deformation, no harmful substances.
4. Good tensile strength performance, after special inspection and testing.
5. Long-term use does not fade yellow does not fade.
6. Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, FDA and SGS standards.

Advantages and disadvantages
Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber. It can be used almost forever at 150° without performance change. It can be used continuously for 10,000 hours at 200° and for a period of time at 350°. . Widely used in applications requiring heat resistance, hot water bottle seals, pressure cooker ring heat-resistant handles.
Cold resistance: ordinary rubber is late for -20°-30°, that is, silicone rubber still has good elasticity at -60°-70°, and some special formulated silicone rubber can withstand extremely low temperature, such as: low temperature. Sealing ring.
Not recommended for use in most thick solvents, oils, thick acids and diluted sodium hydroxide.

Silicone sealing material
Silicone is increasingly favored by people for its environmental performance. To understand the knowledge of silicone products, you must start with silicone raw materials.
1. Silicone raw materials can be divided into ordinary silica gel and meteorological silica gel according to their performance.
Ordinary silica gel
Color: translucent, milky white, light yellow, gray, etc.
Hardness: 30°, 40°, 50°, 60°, 70°, etc., commonly used between 40° and 70°.
Density: 1.1-1.12g/cm2
Elongation: 400%
Uses: The most used are low-end silicone products such as mobile phone buttons, miscellaneous pieces, conductive adhesives.
Meteorological glue, also known as pure silica gel
Color: transparent.
Hardness: 30°, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40° and 60°.
Features: Due to the transparency of this material, the tensile strength is strong. High cost
Uses: Silicone tube, protective cover and other high-end products that require high elasticity.
2. The raw materials of silica gel can be divided into solid silica gel and liquid silica gel according to physical properties.
Solid silica gel is mainly used for compression molded products. For example: silicone sleeve, silicone tableware, silicone buttons, etc., liquid silicone is mainly used for extrusion molding products, such as silicone nipples, silicone tubes and so on.
Insulation silicone pad, excellent high temperature resistance, silica gel (food grade silica gel) can withstand high temperature of 200 ° C and can be used for a long time. The raw materials of this product meet the SGS standard, and pass the FDA food grade silica gel detection standard, tasteless and non-toxic, manufacturers rely on Mold production, color, shape can be customized.
