The short answer
Grivory GV-6H is a 60% glass fiber reinforced polyamide from EMS-GRIVORY, a unit of EMS-CHEMIE. It is not a plain PA66: EMS describes it as a combination of semi-crystalline polyamide with a partially aromatic copolyamide, and its ISO 16396 code is PA66+PA6I/X, GF60. EMS’s data sheet (11/2023) gives density 1.69 g/cm³ (ISO 1183), tensile modulus 22,000 MPa dry and 21,000 MPa conditioned, tensile strength 260 / 240 MPa (ISO 527), HDT 235°C at 1.80 MPa (ISO 75) and a 260°C melting point. EMS positions Grivory GV as an economical alternative to die-cast metal. Grades to ask about include EMS’s own Grivory GVX-6H and GV-6H EF, both PA66+PA6I/X with 60% glass. None is a drop-in replacement; compare data sheets and run a trial.
Also written as: Grivory GV-6H natural, Grivory GV-6H black 9915, GV6H, PA66+PA6I/X-GF60. EMS’s database lists the polymer as PA*-GF60. EMS lists Grivory GV as its glass-fiber reinforced, very stiff Grivory G line. Do not confuse it with Grivory GVX-6H (a separate low-warp grade), Grivory HT (EMS’s PPA line) or Grilon (EMS’s PA6 and PA66 line). Quote the full grade and color code from your drawing or bag label.

Grivory GV-6H specs from the data sheet
Typical values for Grivory GV-6H natural from EMS-GRIVORY’s technical data sheet (generated/updated 11/2023) and EMS’s online material database. “Dry” is as molded; “cond.” is conditioned to equilibrium moisture. EMS calls these guidance values, not binding specifications. The lot COA shows what you actually receive. Values only compare at the same test method and condition.

EMS’s online database matches the PDF on the property values it lists, except long-term maximum usage temperature (110°C in the database, 100–120°C on the PDF). Thermal expansion and the processing settings are from the PDF. Electrical resistivity is left out on purpose: the PDF (1014 Ω·m) and EMS’s database (>1013 Ω·m) give different volume resistivity figures, so ask EMS for the current value if your part needs it.
Grades to ask about instead of Grivory GV-6H
These EMS grades share GV-6H’s ISO polymer code (PA66+PA6I/X) and 60% glass level. None is a drop-in replacement: flow, warp, surface, color and approvals differ. If your part, drawing or customer approval names Grivory GV-6H, any change needs that approval and a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| Grivory GVX-6H | EMS-GRIVORY | Not published on the data sheet | 1.69 g/cm³ (ISO 1183) | Tensile modulus 22,500 / 22,000 MPa and strength 290 / 260 MPa dry / cond. (ISO 527); HDT 250°C at 1.80 MPa and 205°C at 8.00 MPa (ISO 75); Charpy notched 15 kJ/m²; shrinkage 0.05 / 0.25% | Ask about. Same PA66+PA6I/X with 60% glass, same density. EMS lists very low warpage and improved mechanical isotropy, with higher strength and HDT than GV-6H. It is a different grade with its own approvals, so it still needs a trial. Quote this alternative › |
| Grivory GV-6H EF | EMS-GRIVORY | Not published; EMS database lists “high flow” | 1.69 g/cm³ (ISO 1183) | Tensile modulus 22,000 / 21,000 MPa and strength 260 / 240 MPa dry / cond. (ISO 527); HDT 235°C at 1.80 MPa (ISO 75); shrinkage 0.05 / 0.30% | Check. Same polymer, glass level and published mechanical data. EMS describes it for parts with good surface quality and short cycle times, and its database tags it high flow. Its English sheet is dated October 2013, so ask EMS for the current one.

From EMS-GRIVORY’s published data sheets. A standard PA66 GF60 or a PPA is a different polymer, not a like-for-like swap: water uptake, stiffness after conditioning and heat behavior change. We have not listed other producers’ grades because we could not confirm the same PA66+PA6I/X, GF60 makeup on their sheets; ask and a chemist will compare current sheets.
What the PA66+PA6I/X code means
EMS’s nomenclature line reads ISO 16396-PA66+PA6I/X,GF60. In plain terms: a PA66 blended with a partially aromatic copolyamide (PA6I/X), reinforced with 60% glass fiber. EMS says the GV range is based on semi-crystalline polyamides with partially aromatic content, which is why GV-6H keeps most of its stiffness after it absorbs moisture: the modulus only drops from 22,000 to 21,000 MPa when conditioned. EMS’s range page lists “little change in property values after absorption of moisture” as a key trait of Grivory. See glass-filled nylon and nylon swelling from moisture.
Typical uses for Grivory GV-6H
EMS describes Grivory GV-6H for injection molded technical parts that need, even after moisture absorption:
- High stiffness and strength
- Dimensional stability and low warpage
- Good chemical resistance and good surface finish
EMS calls Grivory GV the economical alternative to die-cast alloys. EMS’s Grivory GV range page calls it “the proven material for metal replacement.” For metal replacement projects, see best plastic to replace metal.
What to check before you switch
- Polymer: GV-6H is PA66+PA6I/X, not plain PA66. A PA66 GF60 from another producer will absorb water and lose stiffness differently. Compare conditioned values, not just dry. See PPA vs. PA66.
- Glass level: 60% glass is heavy (1.69 g/cm³) and abrasive. EMS asks for wear-protected screws and mold steel hardened to 56 HRC, with extra wear protection at gates and hot runner nozzles.
- Warp: shrinkage is 0.05% with flow and 0.30% across it. If flat parts warp, ask about GVX-6H, which EMS lists for very low warpage. See warped parts.
- Moisture: EMS ships it dry in sealed bags, so pre-drying is not needed. Once a bag is open, dry at no more than 80°C in a desiccant dryer, because EMS warns that polyamides oxidize and yellow above that.
- Chemicals: EMS’s database marks GV-6H as resistant to motor oil and DOT 4 brake fluid at 130°C and 50% glycol at 108°C, and not resistant at 23°C to 36% hydrochloric, 40% nitric, sulfuric (38% and even 5%) or 40% chromic acid, 10% sodium hypochlorite, hydrogen peroxide or 5% phenol solution.
- Drinking water and food contact: do not assume GV-6H is approved. EMS’s database page for GV-6H natural shows no drinking-water approval, and NSF’s current NSF/ANSI/CAN 61 listings (checked November 2026) show no EMS-CHEMIE entry. EMS markets its Grivory GV FWA grades for contact with drinking water and food. Ask EMS for current certificates for your exact grade and color.
- Flame rating: HB at 0.8 mm only. Ask for a UL yellow card if your part needs a listed rating.
- Run a trial lot and check fill, glass on the surface, warp and weld line strength before you switch production.

Buying Grivory GV-6H: 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. We have access to 100+ 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. Lead time is confirmed with your quote.
- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, natural vs. black 9915 or a custom color, ship-to region, and whether you need Grivory GV-6H itself or can accept a matched alternative. See how resin is priced.
- Paperwork. Supplier COA on every prime lot (what a COA shows). EMS says its safety data sheet can be requested with every order. Ask for any approval letter your part needs.
- Trying an alternative? Start with one gaylord as a trial lot. Samples (~50 lb) are available upon credit approval. Custom compounding and color matching are available.
- If Grivory GV-6H itself is not available. 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.

Common questions
What is Grivory GV-6H?
A 60% glass fiber reinforced polyamide from EMS-GRIVORY (EMS-CHEMIE). EMS describes it as semi-crystalline polyamide combined with a partially aromatic copolyamide; the ISO 16396 code is PA66+PA6I/X, GF60. It is used for stiff, dimensionally stable injection molded parts.
Is Grivory GV-6H a PA66 or a PPA?
Neither exactly. EMS codes it PA66+PA6I/X, a PA66 blended with a partially aromatic copolyamide. EMS sells its PPA separately as Grivory HT.
How much glass is in Grivory GV-6H?
60% glass fiber, per EMS’s data sheet (GF60 in the ISO code). Density is 1.69 g/cm³ (ISO 1183).
What is the heat deflection temperature of Grivory GV-6H?
235°C at 1.80 MPa and 175°C at 8.00 MPa (ISO 75, dry). The melting point is 260°C. EMS’s data sheet lists a long-term maximum usage temperature of 100–120°C (ISO 2578; its online database gives 110°C) and 220°C short term.
Does Grivory GV-6H need drying?
EMS ships it dry (moisture ≤ 0.10%) in sealed bags and says pre-drying is not necessary. If a bag is damaged or left open, dry in a desiccant dryer at no more than 80°C for 4–12 hours, or a vacuum oven at no more than 100°C.
What are the molding temperatures for Grivory GV-6H?
EMS lists a 270–300°C melt and an 80–120°C mold, with barrel zones starting at 260, 270 and 275°C and a 270°C nozzle.
What is equivalent to Grivory GV-6H?
No grade is a drop-in replacement. The closest grades to ask about are EMS’s Grivory GVX-6H (same polymer and glass, lower warp, higher strength) and GV-6H EF (same published mechanical data, higher flow). Compare data sheets, run a trial and get approval if your part names GV-6H.
