- Polyamide - Epichlorohydrin Resins
(Polyaminoamide - epichlorohydrin) resins have been
manufactured at BIP’s Oldbury site for over 30
years and extensively used in the Paper industry to
impart wet strength for applications such as tissues
and paper towels. Originally developed to provide an
alternative to acid curing formaldehyde resins, these
polymers are strongly cationic and rapidly thermoset
under neutral - alkaline pH’s.
The technology has undergone many modifications and
BIP’s latest low AOX (absorbable organic halogen)
products are designed for more specialist applications,
which take advantage of the polymers high charge density.
These include textile and paper processing aids in
addition to conventional wet strength processes.
