COR72 / COR78 Series

Families of isophthalics are offered in filled or non-filled systems and terephthalics come in filled systems specifically developed for Cured-in-Place-Pipe (CIPP) applications. The resins provide excellent corrosion resistance. They have good wet-out characteristics of felt and reinforcements, excellent catalyzed stability, their viscosity is designed to eliminate slugging issues, and they have predictable gel and cure times. They offer cost effective choices for pipeline renovations.


CORVE8190

Our vinyl esters also have been specifically developed for CIPP applications. They have premium corrosion-resistant characteristics and physical capabilities. They meet “Green Book” standards for use in Los Angeles, Calif.


CORVE8738

This novolac vinyl ester is designed for highly corrosive, high-temperature CIPP applications.



Interplastic offers a dependable CIPP “Green” resin that eliminate your environmental concerns.

Interplastic’s CIPP “green” resin lets you repair partially or fully deteriorated underground pipes with environmental safety in mind. Our ground-breaking ECO series resin has no styrene, no VOCs, and no HAPs.

With the same polymer backbone approved for today’s pipeline remediation, the new resin is a proven solution in gravity pipelines that provides consistent quality, fast wet out, trouble-free processing, superior strength, and higher flexural modulus properties.

It meets ASTM F216 requirements and reduces the likelihood of stress cracking and shrinkage with a lower exotherm.
