Raffinate is a petroleum product that is a byproduct of the refining process. It is composed of hydrocarbons, sulfur, and nitrogen compounds. Common uses for raffinate include fuel, lubricants, and solvents.
When rubber is exposed to raffinate, it can suffer from a variety of failures. These failures can range from swelling and softening to cracking and embrittlement. The rate of failure depends on the type of rubber and the concentration of raffinate to which it is exposed. Generally, the higher the concentration and the longer the exposure, the more severe the failure. Additionally, the presence of sulfur and nitrogen compounds can cause the rubber to degrade over time.
