2. Polyscope: about us
Polyscope is the world’s leading producer and supplier of styrene
maleic anhydride co-polymers.
Polyscope offers the broadest styrene maleic co-polymer product
portfolio for Engineering Plastics and Specialty Polymer applications
under it’s trade name XIRAN ®.
XIRAN ® is commercially available in varying maleic anhydride
content in broad molecular weight range.
Polyscope was founded in 2006 and headquartered in Geleen, the
Netherlands. Currently employing 40 fte’s and growing and is
supported by marketing & sales organisations in the USA, Europe
and Asia-Pacific.
Polyscope operates a polymerization production plant in Geleen. The
XIRAN ® based compounds are produced on in the US and in the
Netherlands with dedicated production lines.
Polyscope serves a wide range of industries globally whereby the
functions XIRAN ® differs per application.
