Highlights and Initiatives

Performance Intermediates & Chemicals

Our Performance Intermediates & Chemicals business reported good performance in 2020, which was driven by increased production volumes and supported by price increases in Vitamin B3. The business was also impacted by the slowdown in consumer electronics and industrial applications.

In response to the growing demand for non-current good manufacturing practice (non-cGMP) intermediates for pharma, agro intermediates and food and feed applications, we successfully launched a major capacity expansion in our Visp (CH) site to produce certain pharma and other intermediates.

Custom Development & Manufacturing Organization (CDMO)

In 2020, our CDMO business performance was driven by the successful scale-up of new projects in Visp (CH), supported by indicators of growth in the fermentation business. Our expansion into new markets - beyond our traditional agrochemical base –- was increasingly successful. Customers positively acknowledged the approach to broaden our offerings with a rising number of enquiries for chemical- and biotechnological- derived custom development and manufacturing projects.

In addition, we are strengthening our positioning as a partner of choice for companies with highly innovative products, where a reliable and trusted supply chain is critical. By possessing one of the broadest backward integration of in-house raw materials in the CDMO business globally, our supply chain has demonstrated its resilience during the peak of the pandemic with uninterrupted delivery. We have also seen increasing demand from the personal care industry for our CDMO services in 2020.

Composite Materials

During 2020, our Composite Materials business felt some headwinds, as the electronics and aviation sectors were negatively impacted by COVID-19. However, we saw solid demand in the industrial sector and a strong project pipeline in certain geographies and applications.

Due to the increased demand of Primaset® Cyanate Ester during recent years, the Composite Materials group decided in 2018 to install another production line in the dedicated plant at Visp (CH). This second line was successfully launched in 2020 and will support the future demand of this product group.
