Naphtha is a generic term for a wide range of petroleum-derived hydrocarbon mixtures. Common uses for naphtha include fuel, solvents, paint thinners, and petroleum-based lubricants.
When rubber is exposed to naphtha, it can cause swelling, softening, or cracking of the material. This can lead to a decrease in the rubber's strength and elasticity, which can cause the rubber to fail prematurely. Naphtha can also cause discoloration or staining of the rubber.
