How to reduce the friction of the combined rubber seal ring?

Sealing rings made of different materials will have more or less friction. Although sealing rings with high friction can provide sealing effect, they will reduce the smooth operation of the equipment and even cause serious damage to the equipment. So how can we reduce the combination of Friction of seal ring? DLSEALS sealing introduces several methods below:

PTFE coating method: A layer of mixed PTFE film is firmly compounded on the inner and outer surfaces of the O-ring, that is, a wrapped sealing ring is used.

Coating method: PTFE is coated on the surface of the rubber seal. The coating method includes spraying method, electrophoresis method, etc.

Surface oxidation method: The surface of rubber and plastic products is treated with metal salts of fluorine, chlorine, bromine, iodine and other oxides, which greatly reduces the friction resistance and wear resistance of rubber seals.

Combined type: Add another bowl-shaped or concave PTFE plastic sleeve to the rubber part to reduce the friction between the compressed silicone sealing ring and the closed surface
