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

◆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.
