WESTON™ TNPP
WESTON™ TNPP phosphite is a versatile phosphite stabilizer which is useful in a large number of polymers such as HDPE, LLDPE, SBR, ABS, PVC and others. In most polymers, WESTON™ TNPP 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 this product 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.
