Is Lexan® the same as Makrolon® or Polycarbonate?

The short answer is no, are they very similar, yes. The reason is that both Lexan® and Makrolon® are brand names, along with Hyzod®, Cyrolon®, Zelux®, Paltuf®, Tuffak®, Ensicar®, Unicar®, Texin®, Apex® and many more. Lexan® is a brand name for SABIC (Saudi Basic Industries Corporation) which acquired the entire General Electric Plastics division several years ago. Makrolon® (formerly Hyzod®) is a trade name for Covestro (formerly Bayer MaterialSciences).

These materials are all Polycarbonate which is a very tough, high impact plastic material. The base resins are very similar, however, the end product varies quite a bit depending on the manufacturer. The Covestro Bayer Makrolon® GP-V material does meet the UL 94 V-0 flame retardant certification (at .220″ thick), and the Makrolon® GP is UL 94 HB rated.

How do I tell the difference between Lexan® and Makrolon®?

Bayer MaterialScience now Covestro

It would be impossible to tell the difference between brands by just looking, unless it still has the masking on, it would take some testing. The majority of both brands of materials are available in a very clear, UV stabilized glazing grade and look identical to the naked eye. This material is excellent for replacing window glass and is virtually unbreakable.

      Hi Greg. Good question. Polycarbonate comes in a variety of lengths depending on the diameter(size) and manufacturer that produces it. Usually 72 inches will be the maximum shipping length size without having to pay an oversize charge for UPS or FedEx.

    Hey Mate, Ordered, (ebay) 21″ X 15″ X 3/8″ sheet claimed to be “LEXAN”, got “Makrolon” instead. Never had any problem over many years with LEXAN, but even in this small piece there is a noticeable “Bowing” in both planes!! Am waiting for feedback from my supplier, but thought I’d run it by you in the interim. Gb bg

      “Lexan” is a SABIC (Saudi Arabia Basic Industries Corporation) brand polycarbonate. Makrolon is a Bayer (now known as Covestro) brand made here in the USA. Both polycarbonates have similiar properties. If you got a piece that bows on both sides then your supplier didn’t store it correctly. All our materials is store flat and shipped flat. We found out through our customers that Makrolon hardly ever came out with defects over the Lexan brand.

    I’m actually looking for the best Polycarbonate material luggage. Any recommendations? I know this is a question off the beaten path but I thought I would try.

      Meridith, almost any quality name in luggage is going to use a quality Polycarbonate to make their luggage. Samsonite, TravelCross, Traveler’s Choice and many others offer a quality hard side Luggage made from Polycarbonate sheet material. If you can research the materials used, the thicker polycarbonate sheets will give you the best performance and impact resistance long term. Hope this helps.
