rubber antioxidants: tmq, 6ppd, ippd chemical products,tmq, also known as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant. it provides excellent protection against heat, oxygen, and flex-cracking, enhancing the durability and performance of rubber products.
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
first grade quality 6ppd rubber antioxidant
recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized.
Rubber Antioxidant 6PPD technical data sheet,application: 6ppd is used for rubber products with high efficiency, low poison and low solvent extraction amount. also used as stabilizer in synthetic rubber which is widely

6ppd rubber antioxidant new markers for sale,the results indicate that ppds and 6ppd-q were detectable in 100 % of the winter pm 2.5 samples, with 6ppd and dnpd being the predominant compounds. the concentration of ∑ppds in pm 2.5 exhibited a range of 15.6–2.92 × 10 3 pg·m −3 , with a median concentration of 117 pg·m −3 .
- Are PPD antioxidants present in all samples dominated by 6PPD and dtpd?
- PPD antioxidants, PPDQs, and other TPs were present in all samples with chemical profiles dominated by 6PPD, DTPD, DPPD, and their corresponding PPDQs.
- Can antioxidant protection be used to detect PPDS and TPS?
- An efficient and stable method for the detection of PPDs and their TPs was developed. Oxidative degradation is the main cause of low extraction efficiency of PPDs and some TPs. Combined strong antioxidant protection for stable extraction PPDs and their TPs was first proposed.
- Can antioxidant 2246 be grafted to SIO 2?
- Zhong et al. proposed a novel solid-phase method to graft the antioxidant 2246 on the surface of SiO 2 with the aid of a silane coupling agent . The as-prepared SiO 2 -s-2246 performed better than pristine antioxidant 2246 in protecting rubber from thermo-oxidative aging because of the elimination of the “blooming” defects.
