6ppd rubber antioxidant: characteristics, applications,6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
- What causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
- There is a linkage between 6PPD-Q in soil and tire rubber wear particles (TRWPs), indicating its origin from sources associated with vehicular activities (Klockner et al., 2019). Approximately 50% of TRWPs can infiltrate the soil, releasing bound chemicals like 6PPD (Klockner et al., 2019).
- What is a fast action accelerator for rubbers?
- 2, 2, 4-trimethyl-1, 2-dihydroquinoline is a rubber antioxidant in pellets form used in rubber compounds... 2-2'-Dithiobis (benzothiazole) is a semi-ultra fast accelerator for rubbers... N-cyclohexyl-2-benzothiazolesulfenamide is a delayed action accelerator for sulphur donor cured diene rubbers...
- Why is 6ppd-q present in soil?
- The presence of 6PPD-Q in soil predominantly arises from the deposition of atmospheric particles or dust that carry 6PPD-Q. Soil samples collected from Hongkong's New Territories and Kowloon roadside showed varied concentrations of 6PPD-Q like 9.50–936 ng/g (Cao et al., 2022).
