Industrial Grade DMT
For general polyester, trading and export requirements where stock, packaging and lead time are central.
PRODUCT CENTER
DMT products, grades and specifications
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 practical stock supply and clear basic specifications are the priority.
- Best fit
- General polyester manufacturers, traders and export buyers
- Key controls
- Purity, melting point and appearance
- Documents
- Batch COA, SDS/MSDS and export documents as required
- Workflow
- Confirm package, volume and schedule, then quote and ship
PHYSICAL PROPERTIES
DMT physical property data
Typical literature values; for engineering design, rely on batch testing and the SDS.

TYPICAL SPECIFICATIONS
Typical quality indicators
Common industry typical control values; the contracted specification and per-batch results follow the technical agreement and factory COA.
