UNIPLEX 83
TRI-N-BUTYL CITRATE
CAS. NO 77-94-1
UNIPLEX 83 is a safe economical
plasticizer approved by the U.S. Food and Drug Administration (FDA) for use in
indirect contact food applications according to Code Federal
Regulation 21:75.105 (Adhesives)
UNIPLEX 83 has been widely formulated/plasticize
in polyvinyl chloride polymers and cellulosic resins as an
"environmentally friendly" replacement to the phthalate plasticizers.
The low odor and excellent color
stability of UNIPLEX 83 make it an excellent general purpose plasticizer. Cellulose nitrate films plasticized with
UNIPLEX 83 have lower volatility loss,
better resistance to yellowing and better adhesion to metals than those
plasticized with dibutyl phthalate.
UNIPLEX 83 is very effective as a
defoamer in protein solutions.
UNIPLEX 83 does not support fungal
growth in resins.
Other uses of UNIPLEX 83 include:
1) PVC Flooring
2) Dairy product cartons
3) Drink bottle caps
4) Food
jar caps
UNIPLEX 83 is economical both on a
cost and a performance basis, while exhibiting excellent compatibility with a
wide range of polymers and resins.
Resins plasticized with UNIPLEX 83 exhibit excellent heat stability and
low toxicity.
