Process oils used in the rubber industry are special liquids used to facilitate the processing and shaping of rubber into various products. These can include mineral, synthetic, or vegetable oils, depending on the technical requirements of the process.
HyPrene process oils from Ergon are authentic naphthenic and paraffinic oils, produced according to precise specifications and designed for a variety of processing applications. HyPrene products have low pour points, good solvency power, low odor levels, excellent color characteristics, and color stability.
