Phthalic acid is also known as 1,2-benzenedicarboxylic acid, and is commonly used as an intermediate in the production of plastics, adhesives, paints, and coatings. It is also used as a preservative in food and in the production of dyes.
When rubber is exposed to phthalic acid, the rubber may become brittle and cracked due to the acid's ability to break down the rubber material. It can also cause swelling, discoloration, and corrosion of the rubber, which can weaken its structural integrity over time. Additionally, phthalic acid can cause significant staining of the rubber and make it more prone to cracking and tearing.
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.
