Makrolon 2805 is a polycarbonate (PC), medium viscosity, general purpose, easy release, available in transparent, translucent and opaque colors, from Covestro. The data sheet lists melt volume flow rate (300 °C / 1.2 kg) as 9.0 cm³/10 min (melt mass flow rate 10 g/10 min) (ISO 1133). Density: 1,200 kg/m³ = 1.20 g/cm³ (0.0434 lb/in³). Grades from other producers to ask about include LEXAN 141 and WONDERLITE PC-110. They are not identical, so compare the data sheets and run a trial before switching.

Makrolon 2805 specs from the data sheet
Typical values from the producer’s published data sheet (Makrolon 2805 (base grade, Covestro ISO data sheet, edition 11.08.2023). Covestro publishes one ISO sheet for this grade; no separate North American ASTM sheet was found.). Typical values are not specifications; the lot COA shows what you actually receive. Values only compare at the same test method and condition.

Grades to ask about instead of Makrolon 2805
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 Makrolon 2805, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| LEXAN 141 | NexPoint Materials (formerly SABIC) | MFR 10.5 g/10 min (300 °C / 1.2 kgf, ASTM D1238) | 1.19 g/cm³ (ASTM D792) | UL 94 HB at 0.71 mm (UL yellow card E121562-220861); notched Izod 801 J/m at 23 °C | Very close flow at the same test condition, but LEXAN 141 is listed only as UL 94 HB, while Makrolon 2805 also carries V-2 at 0.75 mm. LEXAN 141 data is ASTM (Americas sheet) and Makrolon 2805 data is ISO, so impact and modulus numbers are not directly comparable. Not a drop-in replacement. |
| WONDERLITE PC-110 | CHIMEI | MVR 10 ml/10 min (300 °C / 1.2 kg, ISO 1133); MFR 10 g/10 min (ASTM D1238) | 1.2 g/cm³ (ISO 1183) | Medium viscosity; notched Izod 75 kJ/m² at 23 °C (ISO 180/1A); HDT 128 °C at 1.8 MPa unannealed (ISO 75/A) | Similar flow and ISO properties on paper. The CHIMEI ISO sheet lists UL 94 V-2 at 2.5 mm while its ASTM sheet lists V-2 at 1.5 mm, so confirm the UL card. Made in Asia under a different UL file; the sheets we found were hosted by a distributor. Not a drop-in replacement. |

Typical uses for Makrolon 2805
Covestro describes Makrolon 2805 as a general purpose, medium viscosity, easy release polycarbonate for injection molding, available in transparent, translucent and opaque colors. The data sheet marks it as a non-medical and non-food-contact grade.
What to check before you switch
- Pull the UL yellow card for the replacement and confirm the rating at your wall thickness and color.
- Check approvals: the Makrolon 2805 sheet says it is not a medical or food contact grade, so any regulated use needs Covestro's prior written approval or a grade that is approved for that use.
- Dry to the producer's moisture limit before molding.
- If parts are clear, compare clarity, haze and color on molded samples, not just the data sheet.
- Mold trial parts and check fit, flow length and impact before a full switch.
Buying Makrolon 2805 or an equivalent
Send us the grade name, your annual volume and ship-to location. A polymer chemist checks the data sheet and we quote Makrolon 2805 where we can source it, or a qualified equivalent, saying clearly which one you would get. Orders start at one gaylord. For background on this resin family see Polycarbonate grades and buying guide; for several grades at once, use the resin RFQ template.

Common questions
What is Makrolon 2805?
Makrolon 2805 is a general purpose, medium viscosity polycarbonate from Covestro with easy release, sold in transparent, translucent and opaque colors for injection molding.
What is the melt flow of Makrolon 2805?
Covestro lists an MVR of 9.0 cm³/10 min and an MFR of 10 g/10 min at 300 °C with a 1.2 kg load (ISO 1133).
What is equivalent to Makrolon 2805?
Grades with similar flow include LEXAN 141 (NexPoint Materials, formerly SABIC) and CHIMEI WONDERLITE PC-110. Neither is a drop-in replacement: flame ratings, UL files and test standards differ, so compare the sheets and UL cards for your part.
What is the UL 94 rating of Makrolon 2805, and is it food contact approved?
The data sheet lists UL 94 V-2 at 0.75 mm and HB at 2.5 mm (UL recognition). The data sheet says it is a non-medical and non-food-contact grade, and Covestro says it is not intended for food contact or other regulated uses without Covestro's prior written approval.
Can ResinBridge quote Makrolon 2805?
Yes. Send the grade name and volume. A polymer chemist checks it and we quote the grade where we can source it, or a qualified equivalent, and say which. Orders start at one gaylord; U.S. and Canada only.
Need Makrolon 2805 or an equivalent?
A polymer chemist reviews every request, then matches your grade or finds a qualified equivalent and prices it.
What to send for an accurate quote
