SODIUM SULFIDE Resistant O-Rings and Seals
Sodium sulfide, also known as sodium sulphide, is a widely-used chemical in various industries. It is commonly used in the papermaking and textile industry for bleaching and dyeing, for mineral processing and ore flotation, for wastewater treatment, and as an industrial cleaning agent.
When rubber is exposed to sodium sulfide, it is prone to cracking and hardening. This can cause the rubber to become brittle and reduce its elasticity. It can also lead to a decrease in the rubber's tensile strength, making it more prone to failure. In some cases, the rubber can become permanently hardened and corroded, leading to a decrease in its lifespan and strength.
