***Typical Properties
This product in brown to amber granule, Soluble in benzene, chloroform, carbon disulfide and acetone, but not soluble in water. the toxicity is light, pollution is low, fine solution with rubber. This product is combustible, when storing and transporting, always pay attention to fireproof and damp proof
***Recommended Applications
It provides oxidation protection to nearly all elastomer types in a variety of applications, having a wide range of temperatures exposure. Its long persistence in rubber allows it to provide long-term heat aging resistance to rubber compounds. It inhibits oxidation catalyzed by heavy metals such as cooper and manganese. As a result of its high molecular weight, TMQ migrates slowly within the rubber martrix and does not bloom.
***Handling and Storage recommendations
Store TMQ in a cool, dry, well-ventilated area, avoiding exposure of the packaged product to direct sunlight. Usually it can be store on 12 month with the common storing condition.
Recommend use of date is within 6 months.
