High and consistent purity
Confirm both the target and the test method behind the reported value.
HIGH-PURITY DMT
Purity that is tied to performance
For optical and specialty applications, color, ash, metals and organic trace components may matter as much as the headline assay.
OVERVIEW
A broader view of high purity
Use a multidimensional specification and validate the actual process response.
Low-color control
Review melt color or relevant color indicators for the intended application.
Low impurity burden
Set application-relevant limits for ash, metals and organic impurities.
Repeatable supply
Compare samples and batch data to ensure scale-up does not change the result.

FAQ
Frequently asked questions
What does high-purity DMT typically specify?
The high-purity profile targets purity ≥ 99.99% (GC), moisture ≤ 0.01%, acid value ≤ 0.03 mg KOH/g, melting point 140–141 °C, color ≤ 10 Pt-Co and low aldehyde content. Exact limits are agreed per project and confirmed on the batch COA.
Which applications actually need the high-purity grade?
Optical and packaging polyester film, specialty polyester and resin systems, and electronic-material feedstocks — applications where color, clarity and trace impurities influence final performance more than the headline assay.
How does import substitution validation work?
Benchmark your current material's COA against our representative data, run a sample through your own process, and where needed we can help arrange third-party testing so the comparison rests on independent numbers.
Is high-purity DMT available for small trial volumes?
Yes. Samples and small trial quantities are the normal entry point, followed by pilot lots and batch-tracked recurring supply once the material is qualified.
