CALCIUM OXALATE Resistant O-Rings and Seals
Calcium nitrate is also known as Nitrate of Lime, Nitro-chalk and Nitrocalcite. It is commonly used in agriculture and horticulture as a fertilizer and soil amendment, as a food additive, and as a component of explosives.
When rubber is exposed to calcium nitrate, the primary failure mode is that of swelling due to the absorption of moisture from the environment. As the rubber absorbs moisture, it expands, leading to cracking and eventual failure. Additionally, calcium nitrate can cause corrosion of metal parts that come into contact with it and accelerate the breakdown of rubber components.
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.
