Data sheet on examples of AEP hydrophilic materials
Click here to download a data sheet for 3 examles of AEP polymers.

The standard products are based on two types of material:

1. Methyl methacrylate/Vinyl pyrrolidone

2. Hydroxyethyl methacrylate/Vinyl pyrrolidone








2007 Andrews Wright Ltd.

Examples of hydrophilic types:

AEP 40
Low water absorption and swell with maximum mechanical stability and dessicant action.

AEP 50
Most used for encapsulation of other chemical materials for preservation and controlled release.

AEP 60
Most used for moulding and mechanical devices with best combination of mechanical stability and volume expansion.

AEP 80
High volume expansion and water absorption used for wound care and similar applications

Contact lens and implant materials are available in a range of water contents from 61% to 78% and with linear expansions from 1.39 to 1.67.

AEP blends
Blended formulations are made using a combination of proprietry and/or commercial materials for the manufacture of a range of products.
