Calcium propionate, also known as calcium salt of propionic acid, is a preservative used in food production to extend the shelf life of products such as baked goods and dairy products. Common uses for calcium propionate include the production of food additives and as an ingredient in animal feeds.
When rubber is exposed to calcium propionate, the primary failure modes are oxidation and discoloration. The propionate can react with the rubber, causing it to oxidize and break down over time. This can lead to cracks and other forms of physical damage, as well as decreased elasticity and strength. In addition, the propionate can also cause the rubber to discolor and deteriorate over time.
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.
