In the post-war era, chemical products became more prominent. Once again, DSM
saw an opportunity and seized it, providing industrial chemicals and raw
materials for synthetic fibers and yarns. It was not long after this that
worldwide use of coal began to decline; oil and natural gas were much more
profitable and coal was more polluting. By the 1960s, coal production was
waning sharply and in 1975, the Dutch Prime Minister officially closed the
country's last mine. Fortunately, DSM had anticipated this and quickly started
changing its focus. By 1970 chemicals and fertilizers comprised the company's
chief activity, accounting for two-thirds of its turnover. Petrochemicals then
took center stage. In just twelve years profits from raw materials for
plastics grew by a factor of fourteen. No mean feat in view of the fact that
DSM had to fight its way into a market dominated by major companies with
long-established names.
In the 1970s and '80s DSM underwent major reorganizations to ensure itself of
sufficient scale, greater guarantees for market consumption, and
diversification into high-quality plastics and fine chemicals. After 1985, DSM
developed a series of ambitious innovation projects resulting in specialties
such as the polyethylene fiber Dyneema, the
strongest fiber on earth.
In 1989 DSM was privatized and listed publicly. During the 1990s, the company
paid greater attention to creating a balance between commerce and research and
developing value-adding processes and products, particularly products for the
pharmaceutical and the food industries and performance materials for the
automotive and transport industry and the electrics and electronics sector.
