- Toxicity
TME is essentially non-toxic. The LD50 in mice is greater than 5000mg / kg. TME is mildly irritating to abraded skin with a score of 0.6 in the Draize test. TME is not irritating to the eye with a score of 0.0 in the Draize test. No toxicological or allergenic problems have been noted during our many years of production experience.

- Handling
- Handling & Storage
- TRIMET® TME is packaged in 50lb and 25kg multi-wall paper bags with HDPE liners. Super sacks containing 500kg / 1102lb and lined with antistatic LDPE are also available. TME is a combustible solid with a flashpoint (Cleveland open cup) of 160°C. Store in a cool, dry area. Do not store near oxidizers. The moisture content of TRIMET® TME may increase slowly with extended storage.
- Shelf life
- TRIMET® TME has a minimum shelf life of not less than 3 years if stored in its original unopened container and under normal storage conditions. Granular TRIMET® TME Tech storage should be limited to 6 months or less due to a tendency of the product to cake. To minimize caking, pallets should not be stacked on top of each other and storage temperatures should be minimized. High humidity conditions may accelerate caking especially if packaging has been opened.
