S-TMQ CAS 26780-96-1 TMQ
Introduction
Chemical Name:Polymer of 2,2,4-trimethyl-1,2-dihydroquinoline
CAS NO.:26780-96-1
Product Specification:
| Appearance | Amber to Brown Pastilles | |
| Total content of dimer and trimer(HPLC),% |
≥ | 70.0 |
| Isopropyl bis aniline content(HPLC),% | ≤ | 0.20 |
| Content of 4-ADPA,% | 80.0-100.0 | |
| Heat Loss(55±2°C ),% | ≤ | 0.20 |

◆Performance:
-S-TMQ is a high-performance quinoline antioxidant with much higher effective body content than TMQ;
As the content of dimer and trimer in S-TMQ is high, it has excellent heat, oxidative aging and fatigue resistance performance;
Compared with TMQ, S-TMQ has very low content of non-effective body, which has a little impact on the reducibility of insoluble sulfur and can improve the adhesion between rubber and steel wire;
-S-TMQ has low volatility and pollution.
◆Application:
-S-TMQ can be applied to all kinds of rubber products such as tires, rubber tubes, rubber belts, etc.;
-S-TMQ is recommended to be used tire belt, body ply compounds, which can improve cord performance.
◆Packaging:Paper/plastic packages with a net weight of 20kg per package.
◆Transportation Condition:Clear vehicle with ceiling, avoiding sunshine and rain, keeping away from hot source.
