FDA Food Grade Silicone Sealing Ring/O-Ring

Xi'an FDA Food Grade Silicone Sealing Ring/Silicone Sealing Ring

Company Introduction:

       Bomingyang Technology Co., Ltd. is located in Xi'an, Shaanxi Province, and is a technology-based enterprise integrating the research, development, production, and sales of rubber seals. The company mainly produces various rubber seals such as O-rings, X-rings, Y-rings, flat washers, V-rings, ED rings, C-rings, rubber strips, rubber balls, rubber retaining rings, and miscellaneous rubber parts.

Introduction to O-rings:

O-rings are rubber sealing rings with a circular cross-section. Because their cross-section is O-shaped, they are called O-rings.

O-ring Material:

Nitrile Rubber (NBR):

This material can withstand temperatures up to 130°C, with hardness ranging from 50 to 90 degrees. It has a complete range of specifications, good mechanical properties, and resistance to mineral-based lubricants and greases.

Fluorocarbon Rubber (FPM):

This material can withstand high temperatures up to 240°C and has a complete range of specifications. It is known for its excellent performance in high-temperature resistance and chemical resistance. Additionally, it has good anti-aging and anti-oxidation properties, as well as very low gas permeability (especially suitable for vacuum devices). Xi'an FDA Food Grade Silicone Sealing Ring/Silicone Sealing Ring Manufacturer.

Ethylene Propylene Diene Monomer (EPDM):

Temperature range from -50°C to 150°C, with characteristics such as resistance to hot water, steam, aging, and chemicals. It is suitable for hot water, steam, detergents, potassium hydroxide solutions, silicone oil and grease, various dilute acids, and chemical (pharmaceutical) products. Particularly notable is its resistance to glycol brake fluid, but it is not suitable for all mineral oil products (lubricants, fuels).

Silicone Rubber (SI):

Silicone rubber has a wide working temperature range (-60°C to 180°C), is non-toxic and odorless, and has excellent resistance to ozone aging, oxygen aging, light aging, and weather aging. It also has excellent electrical insulation properties, unique surface characteristics, physiological inertness, and high permeability.

Many other materials such as:

Polyurethane Rubber (PU), Natural Rubber (NR), Butyl Rubber (BU), Chlorosulfonated Polyethylene (CSM), Polytetrafluoroethylene (PTFE), Neoprene (CR), Acrylic Rubber (ACR), and many others.

Advantages:

1) Compact structure, easy to install and remove;

2) Suitable for both static and dynamic sealing;

3) Low dynamic friction resistance;

4) A single O-ring can provide sealing in both directions;

5) Low cost.

The specification marking method for O-rings is: inner diameter Фi × cross-sectional diameter d. For example: O-ring 20*2.4, Ⅱ-2 GB1235-76, where 20 represents the inner diameter of the large ring as 20 mm, 2.4 represents the cross-sectional diameter of the rubber ring as 2.4 mm, Ⅱ-2 represents the type of rubber used, GB1235 represents the standard number, and 76 represents the year the standard was published.

O-rings are mainly used for static sealing and reciprocating motion sealing -- simple design.

The cross-sectional structure of O-rings is extremely simple, and they have self-sealing properties, ensuring reliable sealing performance.
