Zytel 70G33L: specs and equivalent grades

Also written as: Zytel 70G33L NC010, Zytel 70G33L BK031. Quote the full code from your drawing or bag label; color and additive suffixes change the grade.

Zytel 70G33L specs from the data sheet

Typical values from Celanese's current Zytel 70G33L NC010 grade data in its Chemille materials database (checked October 2026). Where the older DuPont-era sheet differs, the current Celanese value is shown. Processing settings come from the DuPont-era sheet because Celanese's public grade page does not list them. Dry / conditioned values are shown where the data gives both. Typical values are not specifications; the lot COA shows what you actually receive. Values only compare at the same test method and condition.

Source data sheets are listed at the bottom of this page. Confirm against the current sheet for your exact grade code and color.

Grades to ask about instead of Zytel 70G33L

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 Zytel 70G33L, any change needs your approval and usually a trial.

From each producer's published data. Brand owners and grade names change; confirm on the current data sheet.

Typical uses for Zytel 70G33L

From the producer's data sheet and published listings:

• Stiff, strong injection-molded parts that need glass-filled PA66 (the producer describes 70G33L only as a 33% glass PA66 for injection molding)
• The Zytel family is listed for automotive, furniture, domestic appliance, sporting goods and construction parts
• Parts that need high heat deflection for a PA66: HDT 252°C at 1.8 MPa (ISO 75). HDT is a short-term test, not a use temperature; the older DuPont-era sheet listed UL RTI of 120–130°C at 0.8 mm (confirm the current UL listing)

What to check before you switch

• Glass level: 70G33L has 33% glass. A 30% grade such as Ultramid A3EG6 or Durethan AKV 30 H2.0 is a little less stiff and strong; check deflection-critical features and snap fits.
• Stabilizer package: Celanese lists lubricant and release agent for 70G33L, with no heat stabilizer. Vydyne R533H and Durethan AKV 30 H2.0 add heat stabilizer, which can change color and long-term heat aging. If your drawing calls out a heat-stabilized grade, ask Celanese which Zytel code it calls for; it is not 70G33L.
• Glass-filled nylon shrinks differently along and across flow (0.3 % vs. 1.1 % for 70G33L). Compare both directions, and warp, on first articles.
• Compare dry-as-molded to dry-as-molded. Modulus drops from 10,000 to 8,000 MPa when 70G33L is conditioned; see nylon swelling and moisture.
• Nylon must be dry before molding: the sheet asks for 80°C for 2–4 hours to below 0.2 % moisture. See our resin drying guide.
• 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 Zytel 70G33L: 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 Zytel 70G33L 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 Zytel 70G33L 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.
