Product description

Chemical name: Blend of alkyl-aryl-p-phenylenediamines
Molecular weight: 268/282

Eastman Santoflex™ 134PD is a 1:2 blend of N-1,3-dimethylbutyl-N'-phenyl-p-phenylenediamine (Santoflex 6PPD) and N-1,4-dimethylpentyl-N'-phenyl-p-phenylenediamine (Santoflex 7PPD). Both constituents show comparable activity. Therefore, their blends can be regarded as similar to Santoflex 6PPD in terms of performance in rubber.

Santoflex 134PD functions as a powerful antioxidant and antiozonant for natural and synthetic elastomer compounds and as a synthetic polymer stabilizer. Santoflex 6PPD provides protection against fatigue degradation in both static and dynamic operating conditions.

Santoflex 134PD is very effective as a polymerization inhibitor.

Santoflex 134PD is a liquid at room temperature, providing handling advantages over heated liquid PPDs.
