Calcium phosphate acid, also known as phosphoric acid, is a mineral-based acid commonly used in the production of fertilizers, cleaning products, and food preservatives. Common uses for calcium phosphate acid include the production of food additives, cleaning products, and the production of fertilizers.
When rubber is exposed to calcium phosphate acid, the primary failure mode is that of corrosion. The acid can react with the rubber, causing it to 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 acid 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.
