Request a QuoteThe short answer
NORYL GFN2 is SABIC’s general-purpose, 20% glass fiber reinforced blend of polyphenylene ether (PPE) and polystyrene (PS) for injection molding. SABIC still lists it in its SABIC Specialties material finder, with Americas, Asia and Europe data. Published melt flow is 9 g/10 min at 300°C, 5.0 kg (ASTM D1238). Specific gravity is 1.2 (ASTM D792), tensile modulus is 6,200 MPa (ASTM D638), HDT is 135°C at 1.82 MPa on 3.2 mm bars (ASTM D648) and notched Izod is 119 J/m (ASTM D256). The sheet lists UL 94 HB at 1.5 mm and up and a UL 746C F1 outdoor rating. These are typical values; confirm them on the current producer data sheet. The closest grade to ask about is SABIC’s NORYL GFN2F, which has the same published flow, mechanical and HDT values on SABIC’s Americas sheets and which SABIC says carries “FDA food contact compliance and NSF 61 listings in several colors”. No grade is a drop-in replacement.
Also written as: NORYL GFN2 resin, NORYL™ Resin GFN2, Noryl GFN2, PPE/PS GF20. Drawings and bag labels may add a suffix after the grade (for example GFN2-701). We did not find a SABIC source that defines these suffixes; SABIC’s material finder lists the grade as GFN2 and says all colors are customizable. Quote the full code from your drawing or bag label.

NORYL GFN2 specs from the data sheet
Typical values from SABIC’s NORYL GFN2 technical data sheet for the Americas (revision 20260803, from SABIC’s document server). SABIC’s Asia and Europe data for GFN2 differ in places (for example, the Asia tab lists specific gravity 1.23 and MFR 11.7 g/10 min at 300°C, 5 kg), so use the sheet for the region your resin comes from. Typical values are not specifications. Confirm them on the current producer data sheet; the lot COA shows what you actually receive. Values only compare at the same test method and condition.

Mold temperatures of 80–110°C usually need oil or pressurized water heaters. Check your press and tool before planning a trial.
Grades to ask about instead of NORYL GFN2
The closest option is SABIC’s own NORYL GFN2F, the same 20% glass PPE+PS, which SABIC says carries FDA food contact compliance and NSF 61 listings in several colors. NORYL SE1GFN2 is also 20% glass PPE+PS but contains a non-brominated, non-chlorinated flame retardant. Its Americas sheet gives no melt flow; SABIC’s Europe data show an MVR close to GFN2’s, so treat it as a check. We did not find a current producer-published sheet for a 20% glass PPE+PS from another producer that we could verify, so none is listed. None is a drop-in replacement. If your part, drawing or customer approval names NORYL GFN2, any change needs that approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| NORYL GFN2F | SABIC | 9 g/10 min (300°C, 5.0 kg, ASTM D1238); MVR 8 cm³/10 min (ISO 1133) | Specific gravity 1.2 (ASTM D792) | Tensile modulus 6,200 MPa (ASTM D638); HDT 135°C at 1.82 MPa, 3.2 mm (ASTM D648); notched Izod 119 J/m (ASTM D256); UL 94 HB at ≥1.5 mm; UL 746C F1 | Ask about. Same polymer, glass level and published flow, with matching mechanical and HDT values on the Americas sheet. SABIC adds FDA food contact compliance and NSF 61 listings “in several colors” and positions it for water management parts. Its sheet is an older revision (20241015) and lists thermal expansion over −40 to 40°C rather than −40 to 90°C. Check which colors are listed if you need the food or NSF status.

| NORYL SE1GFN2 | SABIC | Not listed on the Americas sheet. SABIC Europe data: MVR 12 cm³/10 min at 280°C, 10 kg (ISO 1133), vs 15 for GFN2 at the same condition | Specific gravity 1.23 (ASTM D792) | UL 94 V-1 at ≥1.5 mm, 5VA at ≥2 mm, V-0 at ≥6 mm; notched Izod 106 J/m (ASTM D256); HDT 132°C at 1.82 MPa, 6.4 mm (ASTM D648); RTI 110°C electrical | Check. Same polymer and glass level, but it contains a non-brominated, non-chlorinated flame retardant. The Americas sheet (revision 20261106) gives no melt flow; SABIC’s Europe data put its MVR at 12 vs 15 cm³/10 min for GFN2 (280°C, 10 kg), so flow looks similar, but confirm it for your region. Its flexural modulus (5,720 MPa) is measured at a 100 mm span, so it does not compare directly with GFN2’s 50 mm span value. Quote this alternative › |

Typical uses for NORYL GFN2
SABIC lists very low moisture absorption, high strength, hydrolytic stability, low warpage, low specific gravity and dimensional stability among the features of NORYL GFN2. The sheet and material finder name these uses:
- Construction and building components
- Electrical components and displays
- Lawn and garden equipment
- Commercial appliance parts
- Electronic components, and mobile phone, computer and tablet parts (SABIC’s industry list)
- Indoor and outdoor parts, supported by the UL 746C F1 rating
What to check before you switch
- Owner check: the current NORYL GFN2 sheet (revision 20260803) is issued by SABIC, and NORYL is listed in SABIC’s Specialties business. Confirm on your quote who issues the COA and any compliance letters. See who makes NORYL.
- Glass changes everything versus unfilled grades. NORYL 731 is SABIC’s non-reinforced PPE+PS; moving between 731 and GFN2 changes stiffness, shrinkage and warpage, so it needs a tool and part review, not just a material swap. See glass-filled plastics.
- Flame rating: GFN2 is listed UL 94 HB only. If your part needs V-1 or 5VA, look at SE1GFN2 and get approval. See UL 94 flame ratings.
- Food contact or potable water: SABIC calls GFN2F the “FDA food compliant / NSF version” and GFN2 the “NON FDA / NSF version”. Specify GFN2F and confirm your color is listed.
- Dry it properly. The sheet asks for 110–120°C for 3–4 hours, no more than 8 hours cumulative, and 0.02 % maximum moisture. See our resin drying guide.
- Compare melt flow only at the same condition. SABIC measures GFN2 at 300°C, 5.0 kg; other PPE blends may be reported at different temperatures or loads.
- If your approval file quotes an older GFN2 sheet, compare it line by line with the current revision (20260803) and ask SABIC about any change that matters for your part.
- Run a trial lot and check fill, shrinkage, warpage, cycle time and appearance before you switch production.

Buying NORYL GFN2: 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. Lead time is confirmed with your quote, and so are payment terms.
- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, color code (standard or custom color), ship-to region, whether you need the food-contact GFN2F version, and whether you need NORYL GFN2 itself or can accept a matched alternative. Custom compounding and color are available on request. 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 compliance letters 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. Samples (~50 lb) are available upon credit approval.
- If NORYL GFN2 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 and color code, your annual volume and ship-to location. A polymer chemist reviews every request before we quote. For several grades at once, use the resin RFQ template.

What is NORYL GFN2?
NORYL GFN2 is a SABIC injection molding resin: a 20% glass fiber reinforced blend of polyphenylene ether (PPE) and polystyrene (PS). SABIC lists very low moisture absorption, high strength, hydrolytic stability, low warpage and dimensional stability, and a UL 746C F1 outdoor rating. It is still listed in SABIC’s Specialties material finder.
What is the melt flow of NORYL GFN2?
9 g/10 min at 300°C, 5.0 kg (ASTM D1238), and MVR 8 cm³/10 min at the same condition (ISO 1133), per SABIC’s Americas sheet (revision 20260803). These are typical values; confirm them on the current producer data sheet.
What is the heat deflection temperature of NORYL GFN2?
135°C at 1.82 MPa and 140°C at 0.45 MPa on 3.2 mm bars (ASTM D648, unannealed), or 137°C and 143°C on 6.4 mm bars. Vicat B50 is 143°C (ISO 306). The UL 746B relative temperature index is 90°C for electrical and mechanical ratings.
What is the UL 94 rating of NORYL GFN2?
SABIC’s sheet lists UL 94 HB at 1.5 mm and up (yellow card E121562-221161) and an oxygen index of 26 %. It also lists a UL 746C F1 outdoor rating. If your part needs V-1 or 5VA, ask about NORYL SE1GFN2, which is rated V-1 at 1.5 mm and 5VA at 2 mm.
Is NORYL GFN2 food safe?
SABIC makes no food-contact claim for GFN2. Its GFN2 sheet says “*See NORYL GFN2F resin for FDA food compliant / NSF version.” The GFN2F sheet says that grade carries “FDA food contact compliance and NSF 61 listings in several colors.” Ask for SABIC’s letter for the exact grade and color.
What does GFN2-701 mean?
GFN2 is the grade. We did not find a SABIC source that defines the suffix after the dash, and SABIC’s material finder says all colors are customizable. Send the full code from your drawing or bag label and a polymer chemist will check what it calls for.
What is equivalent to NORYL GFN2?
No grade is a drop-in replacement. The closest grade to ask about is SABIC’s NORYL GFN2F, with the same published flow, mechanical and HDT values on SABIC’s Americas sheets, plus FDA food contact compliance and NSF 61 listings in several colors, per SABIC. NORYL SE1GFN2 is a flame retardant 20% glass version; its Americas sheet gives no melt flow, but SABIC’s Europe data show an MVR close to GFN2’s. Compare data sheets, run a trial, and get approval if your part names NORYL GFN2.
