The consistently high quality of the whole production process up to the shipment of the product is guaranteed not only by continuous investments in equipment for the production of compounds, for moulding and for laboratory controls but also by the observance of the Quality System procedures.

A further demonstration of the capacity of INTERMARP to meet market requirements and to offer high-quality, high-performance, long-lasting products time is provided by the international product certifications obtained, such as:

• France - ACS
• Germany - KTW Empfehlungen 1.3.13 - W270
• England - WRc

To guarantee consistent quality INTERMARP makes use of its own laboratory where the principal features of the compounds and end product are tested.

INTERMARP is ISO 9001:2008 certified
