Rostabil tnf
Phosphites
Description
In most polymers, Rostabil TNF (Trisnonylphenol phosphite) is a cost effective, high purity stabilizer that improves color and processing stability during recovery, drying, compounding, processing and end use. Synergism is realized when it is combined with other stabilizers such as hindered phenols. It may be added alone or in combination with the monomers and / or in antioxidant emulsions during recovery and / or during compounding. TNF is excellent in preventing gel formation polymerization, finishing, storage and factory processing. TNF is a versatile phosphite stabilizer which is useful in a large number of polymers such as polyethylene, polypropylene, polystyrene, HDPE, LLDPE, SBR, ABS, PVC and others. TNPP is also a suitable stabilizer for a myriad of elastomers such as SBR, NBR and SIS. It is highly effective in light colored solution and emulsion polymerized elastomers. The use of the TNF phosphite is sanctioned by the Food
