Request a QuoteThe short answer
Dow DMDA-8007 NT 7 is Dow's narrow molecular weight distribution high density polyethylene homopolymer for injection molded crates, cases, trays and tote bins. Dow says it is also suitable for cast film. Dow's technical data sheet gives a melt index of 8.3 g/10 min, measured at 190°C / 374°F, 2.16 kg, ASTM D1238, and density of 0.965 g/cm³ (ASTM D792). Grades from other producers to ask about include Alathon M6580, Marlex 9708, SCLAIR 2908 and Formolene LH6008. They are not identical, so compare the data sheets and run a trial before switching.

The producer's sheet gives no drying step; PE and PP do not normally need drying, but material moved from a cold warehouse into a warm plant can pick up surface condensation, so let it reach room temperature in the closed box before opening.
Grades to ask about instead of Dow DMDA-8007 NT 7
These grades from other producers have similar published specs. None is a drop-in replacement: additive packages, flow at molding shear rates, color and approvals differ. If your part, drawing or customer approval names Dow DMDA-8007 NT 7, any change needs your approval and usually a trial.

Typical uses for Dow DMDA-8007 NT 7
From Dow's product page and technical data sheet:
- Crates
- Cases
- Trays
- Tote bins
- Hygiene non-breathable backsheet films
What to check before you switch
- Flexural modulus is reported differently: Dow and Formosa give a 2% secant value (ASTM D790B), LyondellBasell gives 1% secant and CPChem gives tangent modulus, so the numbers do not compare directly.
- Narrow molecular weight homopolymers trade stress-crack resistance for stiffness: Dow lists ESCR of 2 h for DMDA-8007 NT 7 (50°C, 100% Igepal, F50), and the alternatives list 2 h (LH6008) and < 10 h (Marlex 9708, SCLAIR 2908). Do not use them for stress-crack-critical parts without testing.
- Density is measured by ASTM D792 for Dow and NOVA and by ASTM D1505 for LyondellBasell, CPChem and Formosa.
- Dow's data sheet states FDA, Canadian HPFB and EU compliance for DMDA-8007 NT 7; get Dow's current regulatory letter for your file.
- NT 7 is part of Dow's grade name. Quote and approve against the full name, DMDA-8007 NT 7.
- Compare melt flow, density and impact only at the same test condition and method (ASTM vs. ISO results differ).
- Ask for the producer's food-contact or regulatory letter for the exact grade if the part needs one.
- Run a trial lot and check shrinkage, cycle time and appearance before you switch production.
Buying Dow DMDA-8007 NT 7: price, lead time and lot size
- Lot size. From one gaylord to a railcar. See gaylord, LTL and truckload for typical weights per box.
- Where it ships from. 22+ partner warehouse locations. Material already in a partner warehouse usually moves sooner than a grade that has to come from the producer; your quote says which applies.
- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, color, ship-to region, and whether you need Dow DMDA-8007 NT 7 itself or can accept a matched alternative. See how resin is priced and the monthly market update.
- Paperwork. Supplier COA on every prime lot (what a COA shows). Ask for the producer’s regulatory letter or UL file if your part needs them.
- Trying an alternative? Start with one gaylord as a trial lot, molded and checked before you commit a full release.
- If Dow DMDA-8007 NT 7 itself is not available. Some branded grades are sold only through the producer’s own channels or go on allocation. If we cannot source it, we tell you, then quote a matched alternative with a side-by-side comparison.
Send the grade code, your annual volume and ship-to location. A polymer chemist checks it before we quote; we have been in the resin business for 30+ years. For several grades at once, use the resin RFQ template.
