Lead Dioxide, also known as Lead (II) Oxide, Lead Peroxide, or Plumbic Oxide, is commonly used in the production of lead acid batteries, in glass and ceramics manufacturing, and as a paint pigment.
When rubber is exposed to Lead Dioxide, the chemical can cause an accelerated aging process, leading to cracking, hardening and brittleness, as well as a significant decrease in tensile strength. In some cases, exposure to Lead Dioxide can also cause rubber to become sticky, with a tendency to adhere to itself.
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.
