If you need high-performance technical foam, the OK Company materials – and particularly Microlen – are a reliable, cost-effective option.
Overseas Konstellation Company (typically shortened to OK Company) is a European manufacturer of cross-linked polyolefin foams. Its signature Microlen range offers characteristics similar to Plastazote and the AZOTE range by Zotefoams, but is manufactured with chemical blowing agents (while remaining entirely free of CFCs and HCFCs and meeting stringent European regulatory frameworks). Its foams are suitable for a wide range of applications, particularly for engineered foam inserts and protective packaging.
At Polyformes, we are official distributors and converters of OK Company foams. We have extensive knowledge of Microlen, supplying sheet material and converted products to a wide range of businesses across the UK and beyond.
You can source the following foam materials from Polyformes, in sheet form or as pre-fabricated products.
OK Company’s closed-cell polyolefin foams are manufactured for a broad spectrum of technical and industrial market sectors. Their primary uses include industrial packaging and protection, construction and waterproofing, acoustic and thermal insulation, and marine applications.
OK Company foams are generally safe are manufactured to be as environmentally friendly as possible. All of their cross-linked and non-cross-linked foams are free of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Their foams are also lightweight, fully reusable, chemically resistant, and compliant with current European CE and R.I.T.E. (Reglamento de Instalaciones Térmicas en los Edificios) environmental frameworks.
Microlen is OK Company’s flagship product. It is cross-linked, closed-cell polyolefin foam. Unlike Plastazote and other Zotefoam materials, it is manufactured using checmical blowing agents (instead of nitrogen expansion).
While OK Company maintains its corporate headquarters in Madrid, it splits its manufacturing operations across two industrial facilities in Spain. The first is located at the Polígono Industrial La Serra II in Anglesola (Lleida), and the second is based in the Polígono Industrial Villalonquejar in Burgos. These facilities handle the specialised foaming processes, extrusion, and block laminations for their entire global polyolefin product portfolio.
Overseas Konstellation Company, S.A. (OK Company) is a prominent European manufacturer specialising in the development and production of polyolefin foams.

The company’s core product portfolio centers on both cross-linked and non-cross-linked polyolefin closed-cell foams, which are distributed globally for a broad range of industrial applications. Its signature Microlen range is popular for shock-absorbing product protection, high-performance industrial packaging, buoyancy devices, and construction applications such as underground tunnel waterproofing.
Zotefoams PLC – one the worlds largest foam material manufacturers – acquired OK Company in 2025. This acquisition combined OK Company’s regional manufacturing operations and specialised polyolefin processes with Zotefoams’ extensive global reach and established customer base.
Polyformes has a strong relationship with OK Company (and its parent company, Zotefoams), demonstrating a long history of supplying and converting their foam materials.
