Makrolon® Equivalent Polycarbonate Sheet
Same polymer. Covestro resin available on request. Factory pricing from an IATF 16949 plant.
Makrolon® is Covestro’s (formerly Bayer MaterialScience) trade name for polycarbonate. Bakway extrudes solid, multiwall and corrugated PC sheet from virgin resin sourced from several leading producers — Covestro among them. Quoting a project specified against Makrolon? Send the grade and we cross-match it, with the resin brand locked on your production order where required.

Makrolon® Grade Cross-Reference for Sheet Buyers
Buyers often specify a Makrolon® resin or finished-sheet grade by number. The table below maps common Makrolon® designations to the closest Bakway sheet option. If your print names a grade that is not listed, send the spec — we quote against the resin grade and confirm it on the mill certificate.
| Makrolon® grade in your spec | Typical application | Bakway sheet match |
|---|---|---|
| Makrolon® 2458 / 2805 / 2858 | General-purpose extrusion, medical devices, food-contact parts | Solid clear sheet on Covestro resin grade named in RFQ |
| Makrolon® RX2530 / RX1805 | Optical lenses, glazing, high-clarity sheet | Optical grade PC · 90–92% transmission, low haze |
| Makrolon® ET3113 / 6557 | Flame-retardant sheet, electrical enclosures | FR solid sheet · UL94 V-0 · fire-rating guide |
| Makrolon® AL2647 | LED light guide and diffuser plates | LED diffuser sheet · high haze, uniform glow |

Grade numbers are trademarks of Covestro. Bakway supplies equivalent sheet extruded from virgin PC resin; when your project requires a specific Covestro grade, we quote it by name and issue the mill certificate with the resin source.

Makrolon Equivalent Sheet — Buyer FAQ
Is Makrolon different from other polycarbonate?
Makrolon is Covestro’s brand for the same polycarbonate polymer other leading producers make. Sheet performance depends on virgin resin, the UV co-extrusion package and extrusion tolerances — all verifiable on the datasheet and mill certificate, whatever the brand.
Can you run my order on Covestro resin?
Yes. We buy virgin resin from several leading producers including Covestro (formerly Bayer). Name the resin brand or grade in your RFQ and it is locked on the production order and stated on the mill certificate.
Which sizes and thicknesses are available?
Solid 2–15 mm and multiwall 4–25 mm from 2,100 mm master width, cut to length within container limits; 4×8 ft (1,220 × 2,440 mm) is a standard cut. Corrugated profiles follow fixed profile widths.
What documentation comes with the shipment?
Mill certificate with resin source and batch, dimensional report, and the UV warranty of up to 10 years on specified UV-protected outdoor sheets, subject to written product, installation and environment terms. Production is IATF 16949 conformity for polycarbonate sheet processing, excluding product design; ISO 9001 renewal evidence pending.

Makrolon Grade-to-Grade Replacement Chart
| Makrolon grade | Key properties | Bakway equivalent |
|---|---|---|
| Makrolon 2405 / 2407 | General purpose, high clarity, UV-stabilised | Bakway clear solid PC (UV2, 1.2 g/cm³) |
| Makrolon 2805 / 2807 | Medium viscosity, food-contact grades available | Bakway clear solid PC (food-grade option) |
| Makrolon 3103 / 3105 | High impact, sheet extrusion grade | Bakway clear solid PC (impact-tested) |
| Makrolon 3158 | Flame-retardant V-0 rated | Bakway FR PC (UL94 V-0, GB 8624 B1) |
| Makrolon UV multiwall | Twin/triple-wall greenhouse sheets | Bakway multiwall (4–25 mm, UV-coextruded) |
All Bakway equivalents are extruded from 100% virgin polycarbonate with UV coextrusion, IATF 16949 / ISO 9001 quality systems, and test reports on request. Send your Makrolon spec sheet and we will map it grade-for-grade — most replacements are confirmed within 24 hours.
Is Makrolon being discontinued?
Several legacy Makrolon sheet grades have been rationalised by Covestro in recent years, and lead times for remaining grades have lengthened. Bakway equivalent sheets are stocked and produced continuously — typical lead time 7–10 days for standard grades.
What is a good alternative to Makrolon?
Any extruder of 100% virgin polycarbonate with UV coextrusion can substitute Makrolon for most applications. The key checks are: density (1.2 g/cm³), light transmission, UV stabilisation, flame rating and thickness tolerance. Bakway sheets match Makrolon spec-for-spec at factory-direct prices.
Is Makrolon the same as Lexan?
Makrolon is Covestro’s brand and Lexan is SABIC’s brand — both are premium polycarbonate with similar performance. Bakway equivalent sheets are compatible with either brand’s specifications.
