Quality Assurance

The High Performance Polymers Business Unit, together with the entire Marl site, was validated in 1997 under the EU Eco-Audit (EMAS) regulations. It was also certified according to ISO 14001:2005 for several other activities at the end of 2000.

The management system-certified to ISO 9001:2000 since 1992 is constantly being optimized. The positive resonance among our customers is palpable. Nearly all rated our services and the management system in the highest category.

Depending on the delivery form and application, suitability and consistent quality of our hotmelt adhesives are tested essentially by the following methods:

• Optical melting point (capillary method)
• Kofler melting point
• Melting point (DSC)
• Melt mass-flow rate (MFR)
• Relative solution viscosity
• Particle size distribution
• Bulk density

A short discription of the mentioned methods you can find in the brochure VESTAMELT® Hotmelt Adhesives.
