Tri Nonyl phenyl phosphite is a clear viscous hydrolytically stable
liquid. It is used as an anti-oxidant for various types of polymers,
especially in non-toxic applications such as PVC bottles, food wrapping,
sealing gaskets for food containers etc.
In combination with phenolic anti-oxidants it provides good synergism
to the polymer.
It provides excellent protection against thermal degradation in
polymers and rubbers. It is used in Nitrile, SBR and EPDM type of
rubbers as a polymer stabilizer along with epoxidised oils.
Food
packaging, adhesives, latexes, plastic, polyesters, rubber
as stabilizers and anti-oxidant. In PVC calendering operations
and in the manufacture of PVC Stabilizer, used in lubricants
and petroleum oils as anti-oxidant.
TNPP is a suitable
for diverse elastomers such as SBR, NBR and SIS. It is highly
effective in light colored solution and emulsion polymerized
elastomers. TNPP is excellent in preventing buildup, viscosity
increase and retention of track adhesive. it prevents yellowing
to synthetic rubbers and ABS plastics during the process of
heat. It is effective process stabilizer for thermoplastic
polymers such as polyaster, polyethylene and polypropylene.
