Food grade silicone O-ring
Food grade silicone O-ring
O-ring is a type of silicone rubber sealing ring with a circular cross-section. Due to its O-shaped cross-section, it is called an O-ring or O-ring. It began to appear in the mid-19th century as a sealing element for steam engine cylinders and was widely used as a sealing component in hydraulic and pneumatic systems.
Introduction to Transparent O-ring Materials (SIL, Q):
Advantages: Excellent heat and cold resistance, good ozone and weather resistance, good electrical insulation, and colorless, odorless, non-toxic; (minus 60 degrees Celsius, and high temperature resistance (up to 200 degrees Celsius)
Deficiency: Poor mechanical performance, easy to tear;
Suitable for high and low temperature resistance, insulation, medical and food industry gaskets;
Silicone O-ring hardness and color description:
Hardness: The conventional hardness is 60 degrees, * * low hardness can be 35 degrees, * * high is 85 degrees, with a hardness tolerance of plus or minus 5 degrees.
Color: Silicone is a versatile adhesive that can be adjusted to various colors. There is nothing unexpected that cannot be adjusted. The regular color is transparent, code named T. At the same time, only silicone can be used for transparent color.
Silicone, graded, can be selected according to your usage conditions:
Ordinary silicone: environmentally friendly and non-toxic, conventional sealing
Food grade silicone: non-toxic and odorless, with stable chemical properties, high transparency, and no yellowing. It can be used as an external desiccant for food and medicine.
High tear resistant silicone, which contains the advantages of food grade silicone. Not only is it more transparent than food grade silicone, but it is also resistant to tearing and not easy to break
Specification Description:
1. The general specification is expressed as: inner diameter d1 x wire diameter d2, for example: O-ring 82, where 8 represents the inner diameter of the O-ring is 8 millimeters, and 2 represents the cross-sectional diameter of the O-ring is 2 millimeters;
2. Complete specifications - We have over 4000 sets of molds, including national standards and non-standard ones, following the new national standards, and truly achieving complete specifications.
3. Packaging method: Neutral label, inner diameter within 25MM, wire diameter within 3MM, 5000 pieces/pack, can also be packaged according to customer requirements
Characteristics of O-ring:
1. Small size for easy assembly and disassembly; 2. Both dynamic and static seals are available. 3. Static seals have almost no leakage
4. Using bidirectional sealing 5, low dynamic friction 6, low price, affordable
O-ring sealing principle and requirements
O-ring seal is an extrusion type seal that will not leak when the seal undergoes initial deformation and appropriate stress conditions. Therefore, as long as there is initial pressure on the O-ring, a leak free * * seal can be achieved. O-ring seal is a self sealing structure.
