SHELLAC Resistant O-Rings and Seals
SHELLAC is a natural resin that is secreted by the female lac bug. It is used in many industries for its high gloss finish and its ability to form a protective coating. Common uses for shellac include coating food, nail polish, and furniture finishes.
When rubber is exposed to shellac, the resin can seep into the rubber, causing it to become brittle and discolored. In some cases, the rubber may swell or soften, leading to a decrease in performance and life. The shellac can also react with the rubber's additives, leading to further degradation of the rubber. Additionally, shellac can leave a sticky residue on the rubber, which can attract dirt and dust, leading to further performance degradation.
Fluorosilicone (FVMQ, FSIL)
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
