Santoflex? 6PPD Liquid - Flexsys

Santoflex? 6PPD is a more active antioxidant than quinoline or diphenylamine based antioxidants. Santoflex? 6PPD gives better long term fatigue resistance and ozone protection than IPPD. Due to its specific molecular structure and higher rubber solubility, it is less affected by environmental variables, such as heat or leaching, leading to greater durability.

Rubber Antioxidants and Their Transformation Products: Environmental

Antioxidants are added to natural rubber (NR) and synthetic rubber (SR) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [ 4, 5 ]. In addition, they could also be coated on the NR surface to achieve a similar effect [ 6 ].

Rubber Antioxidants and Their Transformation Products

Antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. However, recent studies have revealed that their transformation products (TPs) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber

Transformation Products of Tire Rubber Antioxidant 6PPD

6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation. To address these data gaps, gas-phase ozonation of 6PPD was

6PPD

6PPD is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as NR, SBR and BR; all of which are common in vehicle tires. [1] Although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance. It is one of several antiozonants based around p -phenylenediamine. [2]

Recent progress in the rubber antioxidants: A review

Separately, 4-(dimethyl-butyl amino)diphenylamine (6PPD), another widely used antioxidant in the rubber industry, a recent study reported that the 6PPD (or already converted 6PPD-quinone) released from the tires reacts to form 6PPD-quinone, which is toxic to coho salmon and causes mass coho salmon deaths in the U.S. Pacific Northwest [59].

49 6PPD-Q is formed through the oxidation of 6PPD by ozone.7 6PPD is widely used 50 as an antioxidant in rubber tires to increase their longevity and protect them from 51 oxidative degradation. The annual consumption of 6PPD in the United States ranges 52 from 50 to 100 million pounds.8 Consequently, there is a pressing need to identify
