POLYGLYCOL Chemical compatibility with O-rings, rubbers, & plastics

Polyglycols, also known as polyethylene glycols (PEG) or polypropylene glycols (PPG), are polymers composed of repeating ethylene oxide or propylene oxide units. They are used in a wide range of applications, including pharmaceuticals, cosmetics, lubricants, and industrial processes. Polyglycols can vary in molecular weight, resulting in different physical properties, from liquids to waxy solids. In pharmaceuticals, they serve as solvents, excipients, and drug delivery agents. In cosmetics, they act as moisturizers, thickeners, and emulsifiers. Industrially, polyglycols are used as lubricants, anti-foaming agents, and in the manufacture of resins and plastics. Proper handling requires the use of protective gloves and goggles to avoid skin and eye irritation. Storage should be in tightly sealed containers to prevent moisture absorption. Disposal should follow local regulations to prevent environmental contamination. Polyglycols are valued for their solubility, versatility, and low toxicity in a wide range of applications.
