Lead Chromate, also known as Chromium Trioxide, is a chemical compound used in a variety of industries such as paint and coatings, ceramics, plastics, and rubber. It is primarily used as an anti-fouling agent and a pigment for coloring.
When rubber is exposed to Lead Chromate, it can suffer from a variety of failures. The rubber can become brittle and suffer from cracking or tearing. This is due to the Lead Chromate reacting with the rubber and causing it to break down. Lead Chromate is also known to be corrosive to certain rubber materials and if left in contact with rubber for too long, it can cause the rubber to degrade and become brittle. Additionally, exposure to Lead Chromate can lead to the rubber becoming more susceptible to oxidation and discoloration. Lead Chromate can also cause blooming, which is a white discoloration on the surface of the rubber due to moisture reacting with the chemical.
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.
