LIGROIN Resistant O-Rings and Seals
Ligroin, also known as petroleum ether, is a volatile mineral oil that is widely used as a solvent in a variety of industries including pharmaceuticals, paint and varnish manufacturing, and in the production of essential oils. It is valued for its low boiling point and ability to dissolve non-polar substances.
When rubber is exposed to ligroin, the rubber can become brittle and crack due to the solvent's ability to penetrate and dissolve certain components in the rubber. In addition, the rubber may not adhere to the surface it was intended to bond to, resulting in a failure of the rubber seal. In extreme cases, the rubber may swell and become soft, leading to a complete loss of structural integrity.
