PTFE coating improves O-ring and shaft
seals
As an alternative to its SSHT non-stick treatment for O rings and rotary shaft seals, Blue Diamond is introducing its innovative SBBT enhanced surface treatment.
As an alternative to its SSHT non-stick treatment for O rings and rotary shaft seals, Blue Diamond is introducing its innovative SBBT enhanced surface treatment SBBT provides similar advantages of low start-up and running friction, with the added benefits of extending wear life, retarding ageing of rubber and improving corrosion resistance of metal substrates

Seals range fills all the gaps
Blue Diamond, specialists in the design and supply of oil seals, holds a vast stock which includes specials.
Whereas SSHT involves a molecular depth alteration in surface characteristics, SBBT bonds an ultra-thin PTFE coating to the base rubber or plastic component and can, in principle, also be applied to metal or wood.
Coating thickness is typically between 5 and 15 microns and can be up to 25 microns, reducing the static coefficient of friction to about 0.05 to 0.07.
This means minimal energy loss in any application, and is particularly important for avoiding torque loss in low power drives.
SBBT has a longer wear life than pure PTFE coatings and can be applied with a much more uniform thickness of material, enhancing the surface with lower friction, improved corrosion resistance and good release properties.
The clean, dry film protects substrates from oils, alcohol, fuels, some inorganic acids and dirt and contaminants which might otherwise shorten the life of the product, retaining high flexibility over a wide temperature range.
It does not deteriorate on storage or where components remain dormant for long periods between spasmodic operations.
SBBT treated O rings and seals are easier to assemble, without a need for messy pregreasing operations.
The coatings are available in a range of attractive colours to enable quick differentiation between types or duties. Request a free brochure from Blue Diamond Technologies ...
