Zinc stearate is a zinc salt of stearic acid that is used as a lubricant, release agent, and plastic/rubber additive. It is commonly used in the plastics, rubber, and cosmetics industries.
When rubber is exposed to zinc stearate, there is potential for the rubber to degrade due to oxidation. This can lead to cracking, brittleness, and a decrease in the elasticity of the rubber. Additionally, zinc stearate can act as a plasticizer and reduce the tensile strength of the rubber. It can also cause discoloration of the rubber if it is exposed to high temperatures or UV light.
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.
