O-ring frosting in detail

<p>&nbsp;&nbsp;Frost phenomenon, the mixture of unvulcanized or vulcanized rubber products moves inside, and some substances precipitate on the surface of the O-ring, and the surface of the <a href="dshseals.com" rel="noopener noreferrer" target="_blank">O-ring seals manufacturers</a> will be completely covered. Anti-aging agents such as sulfur paraffin waxes tend to bloom.</p><p>&nbsp;&nbsp;The blooming phenomenon, the rubber component technology may occur intentionally (increased ozone resistance) and occasionally.</p><p>1) Solubility (miscibility of rubber and mixture) is small.</p><p>2) Mobility (the mobility of the compound in the rubber) is large</p><p>3) The difference between the rubber surface and the inside of the frost.</p><p>&nbsp;&nbsp;&nbsp;But in fact, there are many kinds of mixtures in rubber products, which will also cause blooming. And even if blooming occurs, the difference in the concentration of blooming components will be affected by evaporation, emission or air oxidation. After the rubber is exposed to air, frosting will occur within a few hours with different oxidation conditions.</p><p>&nbsp;&nbsp;&nbsp;The frost phenomenon can only be judged based on experience, there is no complete theoretical explanation. The following presentation is part of the report, which is for reference only.</p><p>&nbsp;&nbsp;a) Light, especially a short-wavelength fluorescent lamp, is prone to frost.</p><p>&nbsp;&nbsp;b) The rubber surface is rubbed, and frost is easy to occur when the wind blows.</p><p>&nbsp;&nbsp;c) If you touch it by hand, frost will easily occur through your fingerprint.</p>
