Request a QuoteThe short answer
Durethan BKV30H2.0 is Envalior’s heat stabilized PA6 with 30% glass fiber (PA6-GF30) for injection molding. It is Envalior’s current name for the grade Lanxess listed as “Durethan BKV 30 H2.0”; plain Durethan BKV30 (once written BKV 30) is a separate grade without the heat stabilizer. Durethan was a Lanxess brand until April 1, 2023, when it moved to Envalior. Envalior is majority owned by Advent International, and Lanxess still holds a minority stake of about 41%. Published values (Envalior property data, dry / conditioned): density 1,360 kg/m³ (ISO 1183), viscosity number 140 cm³/g, tensile modulus 9,600 / 6,000 MPa and stress at break 180 / 110 MPa (ISO 527), HDT 205°C / 401°F at 1.8 MPa (ISO 75), melting point 220°C, and HB at 0.75, 1.5 and 3.0 mm (IEC 60695-11-10). Envalior lists drying at 80°C, a 250–285°C melt and a 50–80°C mold. The sheet lists no melt flow (MVR). These are typical values; confirm them on the current producer data sheet. Grades to ask about include BASF’s Ultramid B3WG6 (heat aging resistant) and Ultramid B3EG6. None is a drop-in replacement.
Also written as: Durethan BKV 30 H2.0, BKV30 H2.0, Durethan BKV30H2.0 901510 (a black color code; Envalior also lists 900116, 900812 and natural on its FMVSS certificates), PA6-GF30. Durethan BKV30 (no H2.0) and BKV30H2.0EF are separate grades. Quote the full grade and color code from your drawing or bag label.

Nylon 6 takes on water after molding. Stiffness on this sheet falls from 9,600 MPa dry to 6,000 MPa conditioned, so check which column a drawing or spec refers to. See nylon swelling and moisture.
Grades to ask about instead of Durethan BKV30H2.0
These are PA6 with 30% glass fiber from another producer, with the same viscosity number (140 cm³/g), which points to a similar flow class. Envalior publishes no MVR for BKV30H2.0, so flow cannot be compared directly. None is a drop-in replacement: stabilizer packages, color and OEM approvals differ. If your part, drawing or customer approval names Durethan BKV30H2.0, any change needs that approval and a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| Ultramid B3WG6 | BASF | MVR 30 cm³/10 min (275°C / 5 kg, ISO 1133); viscosity number 140 cm³/g | 1.36 g/cm³ (ISO 1183) | Tensile modulus 9,500 / 6,200 MPa and stress at break 185 / 115 MPa, dry / conditioned (ISO 527); Charpy notched 15 / 30 kJ/m²; HDT 210°C at 1.8 MPa (ISO 75); UL 94 HB at 3.05 mm | Ask about. BASF calls it heat aging resistant, so it is the closer match to the H2.0 version. Same density and viscosity number; HDT 5°C higher on the sheet; slightly higher conditioned stiffness and impact. BASF lists an 80–90°C mold and 270–290°C melt, hotter than Envalior’s ranges. Stabilizer packages differ. See our Ultramid B3WG6 page. Quote this alternative › |
| Ultramid B3EG6 | BASF | MVR 35 cm³/10 min (275°C / 5 kg, ISO 1133); viscosity number 140 cm³/g | 1.36 g/cm³ (ISO 1183) | Tensile modulus 9,500 / 6,200 MPa and stress at break 185 / 115 MPa, dry / conditioned; Charpy notched 15 / 30 kJ/m²; HDT 210°C at 1.8 MPa; UL 94 HB at 3.05 mm | Check. BASF’s standard PA6 GF30 for industrial and electrical insulating parts, not described as heat aging resistant. It is closer to plain Durethan BKV30 than to the H2.0 version, so check long-term heat needs first. See our Ultramid B3EG6 page. Quote this alternative › |
| Durethan BKV30 | Envalior | Not listed; viscosity number 140 cm³/g | 1.36 g/cm³ (ISO 1183) | Same mechanical and thermal values as BKV30H2.0 on Envalior’s sheets; CTI 600 V; GWFI 600°C at 2 mm; shrinkage 0.25 / 0.75 % | Check. Same producer and base, without the heat stabilizer. It differs on GWFI (600°C at 2 mm vs 700°C at 1.5 mm), CTI (600 vs 425 V), electrical values and shrinkage. Use it only where the part does not need heat aging resistance and the approval allows it. Quote this alternative › |
From each producer’s published data; typical values, confirm on the current producer data sheet. Brand owners and grade names change.
Typical uses for Durethan BKV30H2.0
Envalior names BMW, Ford, GM, Mercedes, Renault, Stellantis and VW as automotive OEMs for this grade, lists three OEM specifications, and gives a current distribution ring as an application example. Typical uses for heat stabilized PA6 GF30 include:
- Automotive parts that must meet one of the OEM specifications listed above
- Current distribution rings and other electrical parts (Envalior application example)
- Structural brackets, housings and covers that see heat over time
- Parts that must keep stiffness at temperature (the sheet lists 2,500 MPa tensile modulus at 200°C)
What to check before you switch
- Owner check: Durethan is now an Envalior brand (Envalior is majority owned by Advent International, with Lanxess holding about 41%). Older approvals, COAs and UL files may say Lanxess. See who makes Durethan and the brand ownership tracker.
- Pick the right version. BKV30 (not stabilized), BKV30H2.0 (heat stabilized) and BKV30H2.0EF are separate grades. OEM approvals follow the exact grade and color code.
- Dry vs conditioned. Envalior gives both columns. Compare dry with dry when you look at BASF or other sheets.
- No published melt flow. Compare viscosity number (140 cm³/g), then confirm flow in a trial.
- Dry it right. Envalior asks for a dehumidified or vacuum dryer at 80°C and says hot air ovens are not suitable. See our resin drying guide.
- PA6 or PA66? PA66 GF30 melts higher and holds more heat. They are not interchangeable without approval. See nylon 6 vs nylon 66 and PA66 GF30 properties.
- Flame rating. The property sheet gives HB by IEC 60695-11-10 only. Envalior’s grade page links a UL yellow card (file E245249); if your part needs a UL listing, check that card for your color and thickness. See UL 94 flame ratings.
- Run a trial lot and check fill, surface finish, shrinkage, warp and conditioned dimensions before you switch production. See PA6 GF30 properties for typical ranges.

- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, color code, stabilized vs standard version, ship-to region, and whether you need Durethan BKV30H2.0 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 OEM approval letters, FMVSS certificate or UL file if your part needs them. Payment terms are confirmed with your quote.
- Trying an alternative? Samples (~50 lb) are available upon credit approval, or start with one gaylord as a trial lot. Custom compounding and color matching are available.
- If Durethan BKV30H2.0 itself is not available. If we cannot source it, we tell you, then quote a matched alternative with a side-by-side comparison.

Common questions
What is Durethan BKV30H2.0?
Durethan BKV30H2.0 is Envalior’s nylon 6 (PA6) with 30% glass fiber, heat stabilized, for injection molding. It is Envalior’s current name for the grade Lanxess listed as Durethan BKV 30 H2.0 (with spaces). Plain Durethan BKV30, once written BKV 30, is a separate grade without the heat stabilizer.
Who makes Durethan now?
Envalior. Durethan was a Lanxess brand and moved to Envalior on April 1, 2023. Envalior is majority owned by Advent International, and Lanxess still holds a minority stake of about 41%. Older paperwork may still say Lanxess.
What is the density of Durethan BKV30H2.0?
1,360 kg/m³ (1.36 g/cm³, ISO 1183), the same as BASF’s Ultramid B3WG6 and B3EG6.
What is the heat deflection temperature of Durethan BKV30H2.0?
205°C / 401°F at 1.8 MPa and 220°C at 0.45 MPa, dry (ISO 75). The melting point is 220°C. These are typical values; confirm them on the current producer data sheet.
How do you process Durethan BKV30H2.0?
Envalior lists drying at 80°C for 2–6 h in a dry air dryer, a measured melt of 250–285°C and a mold of 50–80°C. It says melt residence time should be 6 minutes or less and should not exceed 10 minutes.
What is the difference between Durethan BKV30 and BKV30H2.0?
H2.0 adds a heat stabilizer. On Envalior’s sheets the mechanical and thermal values are the same, but BKV30H2.0 lists a higher glow wire flammability index (700°C at 1.5 mm vs 600°C at 2 mm), a lower CTI (425 vs 600 V), different dielectric values and electric strength (35 / 30 vs 40 / 35 kV/mm, dry / conditioned) and slightly different shrinkage. OEM approvals are grade specific.
What is equivalent to Durethan BKV30H2.0?
No grade is a drop-in replacement. The closest grade to ask about is BASF’s Ultramid B3WG6, a heat aging resistant PA6 GF30 with the same density and viscosity number and HDT 210°C. Ultramid B3EG6 is BASF’s standard version. Compare data sheets, run a trial and get approval if your part or OEM spec names Durethan BKV30H2.0.
