CAS: 25322-68-3
Polyethylene Glycols (PEGs) are synthetic polymers of particular chemical properties with multiple applications are well known. The products are all known to be made from molecular weight customize compounds, which enables options in multiple sectors. Their non-toxic and hydrophilic nature also differentiates them from other polymers and makes them safe for be suited to multiple applications como use in medical and personal care products. They can be modified into various forms, from solids to liquids, depending on their intended use, and continue to be studied for applications like drug delivery and biotechnology.

Applications in Plastic & Rubber
Polyethylene glycols are Plasticizers that increase flexibility and reduce brittleness in rubber and plastic goods. Their use in production techniques allows easier processing of the material, being easy to mold and shape. Additionally, PEGs contribute to the durability and resilience of end products, making them indispensable in the production of synthetic rubber and thermoplastics.
Additional Industrial Applications
PEGs also find significant applications across various other industries, including:
● Pharmaceuticals: Used as excipient and in drug formulation to increase solubility
● Personal Care: Commonly found in creams and lotions for their moisturizing properties.
● HI&I (Household, Industrial & Institutional): Such as solubility and safety lauched into cleansing products market.
● Food & Nutrition: used as food additives and stabilizers.
● Agriculture: Utilized as carriers for pesticides and fertilizers.
