Food Grade Leak Proof Silicone Sealing Ring Gasket

Product Specification

Food Grade Silicone Rubber Ring Fresh-Keeping Box O-Ring Leak Proof Ring Silicone Gasket

1. Specification parameters

  The rubber strip is a strip colloid used for bonding, repairing or gluing the tire and tread. It integrates a unique cold and heat-resistant process formula. It has excellent air tightness, so that the repaired tire can adapt to various road environments all day, effectively improve the wear resistance and service life of the retreaded tire, and make the retreaded tire more beautiful. Rubber Seal can produce solid rubber strip, hollow rubber strip, conductive rubber strip, foam rubber strip and special-shaped rubber strip of the following materials. Different cross-section structures can be designed according to the parts and conditions of use. Most customers are generally made of chloroprene rubber, ethylene propylene diene monomer rubber, silicone rubber and other rubber materials with excellent aging resistance due to the requirements of UV aging resistance and ozone resistance. Of course, we also have the ability to produce garlast? Ffkm perfluorinated rubber products. Our manufacturing methods are extrusion continuous vulcanization, extrusion vulcanization tank vulcanization or molding vulcanization. You can also tell us any geometry you need. Contact the sales personnel of RAST sealing products, and we will send technical personnel to assist you to complete the specified sealing system.

2. Data Sheet

3. Used

O-ring is mainly used for static seal and reciprocating seal. When used for rotary motion sealing, it is limited to low-speed rotary sealing device. The rectangular sealing ring is generally installed in the groove with rectangular section on the outer circle or inner circle to seal.

4. Matters needing attention

During the installation of the seal ring, attention should be paid to keeping the surrounding environment clean. If a large number of dust, sediment and other impurities enter the edge of the seal ring in the installation environment, it is easy to cause the wear of the seal ring and affect the sealing effect. The long-term existence of these impurities is a great hidden danger for the normal use of the seal ring in the later stage.

5. Technology

Solid rubber strip, hollow rubber strip, conductive rubber strip, foam rubber strip and special-shaped rubber strip can be designed with different cross-section structures according to their use parts and conditions. Most customers are generally made of chloroprene rubber, ethylene propylene diene monomer rubber, silicone rubber and other rubber materials with excellent aging resistance due to the requirements of UV aging resistance and ozone resistance.

6. principle

The rubber sealing component, which can prevent dust, air and water from entering the system, mainly uses the elasticity of the lip, cavity, flange and other parts of the body structure and the contact pressure generated by the surface of the assembled object (glass, metal parts, etc.) to play the role of sealing and vacuum.

7. Purpose

It is used in electric power system, automobile, aircraft, large air filter, refrigerator and various industrial parts. Rubber sealing strip is a kind of rubber sealing component which can prevent dust, air and water from entering the system

8.  Advantage

The sealing ring can adapt to the pressure and temperature in different working environments, and has good sealing performance within the specified range, and the user can also appropriately adjust the sealing performance of the sealing ring according to the actual use.

10. Production process

Extrusion vulcanization can vulcanization or molding vulcanization.

Rubber sealing strips can be classified according to section shape, vulcanization method, application position and purpose, material and other methods.

(1) Discontinuous vulcanization method (cut the extruded rubber strip according to a certain length, put it into the vulcanizing tank for vulcanization, and extrude the semi-finished rubber strip

Put it into the model;

(2) Continuous vulcanization (microwave continuous vulcanization, salt bath continuous vulcanization, hot air continuous vulcanization)

In addition, some methods such as chemical method, etc.

Microwave continuous vulcanization composite sealing strip: microwave vulcanization technology is one of the key technologies of foreign energy crisis in 1970s

After the application and widely promoted production technology. Microwave continuous vulcanization technology can not only produce metal core, solid core rubber and sponge

Moreover, it is superior to other continuous vulcanization devices in energy saving and work efficiency improvement.

11. Operation method

Cut the sealing strip to the size you need, then stick it with the special glue for the filter element, and then stick it on the filter element cover with the glue to play an effective sealing role.

12. matters needing attention

Pay attention not to touch too much glue on the adhesive strip, otherwise it will overflow and affect the appearance of the filter element.
