Is Lexan® the same as Bayer Makrolon® or Tuffak® Polycarbonate
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®?
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.
