Industrial Grade DMT
For general polyester, trading and export requirements where stock, packaging and lead time are central.
PRODUCT CENTER
Dimethyl terephthalate (DMT) products and grades
Four supply profiles cover general polyester, engineering plastics, specialty materials and PET chemical recycling.
OVERVIEW
Match the grade to the process
The right starting point is the application and its critical control indicators, not a grade name alone.
Polyester Grade DMT
For PBT, PET and PTT processes requiring consistent moisture, acid value and impurity control.
High-Purity DMT
For film and specialty polyester programs focused on color, clarity and trace impurities.
Recycled DMT
For methanolysis-derived monomer streams requiring purification and repolymerization validation.
GRADE SELECTOR
Four DMT supply profiles
Select a grade to review its application fit, key controls and recommended supply workflow.
Industrial Grade DMT
For general polyester, trading and export programs where source, basic specification, packaging and timing are the first qualification priorities.
- Best fit
- General polyester manufacturers, traders and export buyers
- Key controls
- Assay, appearance, color, moisture and acid value as required
- Documents
- Agree the representative or commercial-lot COA, SDS/TDS and export documents required
- Workflow
- Confirm source, specification, package, volume and schedule before quotation
PUBLIC REFERENCE
DMT identity and literature data

QUALIFICATION MATRIX
Fields to define before comparing DMT offers
A grade name or headline assay is not enough. Put the required limit, method and commercial-lot evidence into the same comparison sheet.
| Field | Why it matters | What the buyer should define | Evidence to request |
|---|---|---|---|
| Identity & assay | Confirms substance and main-component basis | Acceptance limit, unit and analytical method | Specification plus representative or lot COA |
| Color & appearance | Can affect film, resin and specialty-material appearance | Measurement condition and acceptance rule | COA, sample and retained-sample procedure |
| Acid value & moisture | May affect storage history and process stability | Limits, sampling condition and method | COA plus buyer-side verification where critical |
| Ash, metals & organic traces | May affect catalyst, color and downstream performance | Application-specific analytes and reporting limits | Detailed analysis or third-party report |
| Source & batch identity | Connects trial evidence to commercial material | Origin, manufacturing source and change-notification rule | Lot identity and written source confirmation |
| Packaging & delivery | Affects contamination risk, usability and landed cost | Net weight, liner, pallet, destination and Incoterm | Packaging plan and written quotation |
Final acceptance follows the written specification, agreed test methods and evidence for the commercial lot. Review catalyst-sensitive fields separately for CHDM/PETG projects.
