PEG Polymers

PEG Polymers — covers polyethylene glycol polymers of various molecular weights and architectures, including linear forms and multi-arm types with carboxyl end groups. These hydrophilic polymers are commonly used as base materials for surface modification and biomaterials.

PEG Polymers are used by biomaterial and formulation researchers to increase water solubility, reduce non-specific interactions on material surfaces, and serve as a matrix in hydrogel preparation. Multi-arm variants such as 4-arm PEG-COOH enable the formation of three-dimensional crosslinked networks, while low to high molecular weight PEGs are selected according to the viscosity and mechanical properties required for the final product.

Example products in this collection: TCI A3617 4arm-PEG5K-COOH, TCI H0543 25322-68-3 Polyethylene Glycol 300, TCI P2830 25322-68-3 Polyethylene Glycol 20000, TCI N0443 25322-68-3 Polyethylene Glycol 400, TCI P2829 25322-68-3 Polyethylene Glycol 11000, TCI P0840 25322-68-3 Polyethylene Glycol 200, TCI P2828 25322-68-3 Polyethylene Glycol 1000, TCI P0885 25322-68-3 Polyethylene Glycol 4000.

Select based on the average molecular weight, the number of polymer arms (linear or multi-arm), and the type of functional end group that suits the planned conjugation or crosslinking reaction. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.

Other categories at the same level under PEGs, PEGylation Reagents [Biomaterials/Biocompatible Materials Research Reagents], are often used together in one laboratory workflow:
