rubber anti-aging agent antioxidant 6PPD (4020) supplier,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. although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
there are many parameters to consider when seeking to substitute 6ppd, not least type of degradation oxidation, ozone, fatigue, or a combination of these the hutchinson presenter set out.

rapid screening 'can help tire makers address 6ppd issues',hanover, germany concern over the potential environmental and health impacts of 6ppd (6 p-phenylenediamine) antiozonants in tire rubber compounds has raised the need for research in this area. migratable antiozonants, such as 6ppd, are critical for non-wearable areas of the tire such as sidewall and in the tread lugs, explains erick sharp
high-efficiency antioxidant solutions for rubber products
this article discusses the common problems of rubber products under high dynamic working conditions, and how to provide effective solutions for the industry by using the antioxidant 6ppd to provide strong antioxidant protection, enhance the durability and high temperature stability of rubber.
global tire consortium identifies five potential 6ppd,washington a global consortium of 30 tire manufacturers has identified five potential alternatives to 6ppd as an anti-degradant for tires. mobilised by the us tire manufacturers association (ustma), the consortium members have submitted a 'stage 1' alternative analysis report on potential 6ppd replacements.
- Does 6PPD ozonation pose environmental risks?
- 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.
- What are the data gaps in 6PPD ozonation?
- 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 conducted over 24–168 h and ozonation TPs were characterized using high-resolution mass spectrometry.
- 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.
