CAS # 025322-68-3 INCI / CTFA nomenclature—PEG-4 The Dow Chemical Company is a science and technology-based company and one of the world’s largest producers of polyalkylene glycols. Our worldwide research, manufacturing, and distribution includes facilities in Europe, North America, Latin America, and Asia-Pacific. Sustainability Attribute: With over 50 years experience in polyglycol manufacturing, the industry’s broadest product line, and a leadership position in new product development, Dow is uniquely positioned to meet the needs of a diverse global marketplace. This success results from expanding our customers’ markets through combined customer formulation knowledge and Dow alkoxylation expertise in joint development applications. Together we focus these resources to help ensure success for our customers and their products. CARBOWAX™ PEG 200E Polyethylene Glycol is the product of the catalysed reaction between ethylene oxide and water. The polymerisation reaction is controlled so that the average molecular weight is in the range 190–210. CARBOWAX™ PEG 200E Polyethylene Glycol, at room temperature, is a clear, hygroscopic liquid, which possesses a characteristic low vapour pressure and excellent lubricity. It is totally soluble in water and in most organic solvents except aliphatic hydrocarbons. At high temperatures and in the presence of air CARBOWAX™ PEG 200E Polyethylene Glycol will undergo decomposition. However, improved stability can be gained by the use of antioxidants. As CARBOWAX™ PEG 200E Polyethylene Glycol contains two terminal hydroxyl groups it can be used in polyurethane and esterification reactions.
Melt Flow Index (MFI) at 230°C / 2.16 kg, density, polymer melting point and tensile strength. The full Technical Data Sheet (TDS) is available on request.
Suited to injection moulding and forming applications such as rigid containers, caps and engineering parts that demand high stiffness and dimensional stability.
