Additives for polyurethanes

PU product range Addocat® catalysts
Standard and customized special catalysts for poly-
urethane flexible foams, rigid foams and CASE appli-
cations
Addovate® stabilizer
Standard and special stabilizers for flexible and rigid
polyurethane foams
Addovate® dispersing agents, additives
Silicone-free stabilizers and emulsifiers for flexible
ester foams and additives e.g. anti-scorch agents or
anti-discoloration agents

Customized catalysts
Rhein Chemie's production facility enables the
processing of both liquids having an ignition point
below 200 °C and solid compounds. The production
of customized catalysts including packaging in va-
rious kinds of containers, standard and tailor-made,
fully complies with all applicable legal and internal
safety criteria. High quality and flexibility are in fact
the main competence of Rhein Chemie

Main applications Metal-faced sandwich panels
Laminated boards
Spray foams
Rigid slabstock foams
Pipe insulation
Insulation for appliances
Technical special insulation

Rhein Chemie produces high-quality additives espe-
cially designed for use in rigid polyurethane foams.
Best results are obtained when our additives are
used in combination with the well-known polyols and
isocyanates made by Bayer MaterialScience AG.

In addition, Rhein Chemie keeps developing new addi-
tives designed to satisfy the ever-growing demand,
such as compatibility with the new generation of
blowing agents.
