Sonneborn polymer and process oils are a family of highly refined, low-volatility mineral oils consisting of saturated aliphatic and alicyclic nonpolar hydrocarbons. They are hydrophobic, colorless, tasteless, odorless, chemically inert and have excellent UV stability.
Hydrobrite polymer oils are added to plastics such as crystalline polystyrene (PS), high-impact polystyrene (HIPS), polyolefins, thermoplastic elastomers, and various other polymers to improve and control the melt flow rate of the finished polymer. Hydrobrite polymer oils are also employed as internal lubricants and/or external lubricants in PS, PVC, PP, PE, TPE and numerous polymer formulations.
Other applications include: plasticizing agent; catalyst carrier; extender oil; mold release agent; and pigment-dispersing agent.
