Application in Glass Manufacturer

Since 2000, YodaRubber began to extensively develop and manufacture FKM rubber o-ring for glass manufacture industry.

Specifically, in producing the low-e glass, which has excellent thermal and solar performance, a coating process applies in glass production. There are actually two different types of low-e coatings: passive low-e coatings and solar control low-e coatings. Both types of low-e glass, passive and solar control, are produced by two primary production methods – pyrolytic, or “hard coat”, and Magnetron Sputter Vacuum Deposition (MSVD), or “soft coat”.

During the coating process, the glass will be transmitted through metal rollers and the FKM o-rings are tied to the rollers so as to provide buffer insulation between the glass transmitted and the metal roller. As the coating process entails high temperature and chemical substance (metal oxide), the excellent resistance to high temperatures and corrosion (due to ozone, oxygen, mineral oil, chemicals, etc.) makes FKM o-rings perfect candidate for such buffer insulation applied in glass coating process.

A common problem arising from the glass coating process is that the colour (painting material) of the o-ring would drop and dye to the glass. That is, sometimes the mark of the O-rings could be seen on the glass surface.

Several options have been identified to address the problem:

  1. Enhancing the smoothness of the products. Uneven surface of the products, particularly the flash (the rim) of the O-Ring will exacerbate the dyeing problem due to the stress imbalance.
  2. Changing to other colours. For example, white colour (more precisely the semitransparent) is far less remarkable than the green. But note that different colour has different optical effect, which may contradict with the optical requirement of the glass. For example, tinted glass might have different colour reflection. Therefore, it is not entirely free to change colour.
  3. Adjusting the formulation of the FKM compound. Specifically, certain formulation of the compound may strengthen the link or bond between molecules, and therefore hold the painting material more tightly.
