- What is 6PPD used for?
- 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.
- Is 6PPD a toxicity hazard?
- However, this same property facilitates the transfer of 6PPD and its oxidation products into the environment as tire-wear debris. The 6PPD-quinone (6PPD-Q, CAS RN: 2754428-18-5) is of particular and increasing concern, due to its toxicity to fish.
- Are synthetic phenolic antioxidants toxic?
- Also, synthetic phenolic antioxidants (SPAs) are widely used antioxidants in the rubber industry, the toxicity effects of some SPAs, such as BHT and BHA, have been well documented . Moreover, the toxicity effects of some transformation products are likely worse than those of the parent compound .
- Is MBZ 445 a good antioxidant for EPDM?
- In the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (MBZ:445=2:1) is superior to that of other samples (Fig. 2 c), demonstrating the synergistic antioxidative effects between MBZ and 445 for EPDM.
