Basic Description
class molding and extrusion materials created
from DuPont proprietary acid copolymers. Starting with selected molecular weight grades of
• direct adhesion of epoxy and polyurethane
copolymers such as ethylene/methacrylic acid,
DuPont adds zinc, sodium, lithium or other metal
• direct adhesion to metal, glass, and natural
salts. Acid neutralization results in the formation
of ion clusters (hence the general term,"ionomer") within the resulting polymer matrix. Product Range Surlyn resins are designed and manufactured byDuPont to deliver premium end-use performance
