Uhde established itself in Thailand as early as the 1970s, shortly after the oil crisis, and contributed to the rapid growth of the Thai petrochemical sector. It was the construction of the first low-density polyethylene plant for Thai Petrochemical Industry Public Company Limited (TPI) in 1980 that set the ball rolling. The continuing business relationship with TPI resulted in the establishment of Uhde Thailand Ltd. in Bangkok in 1990, with TPI as a shareholder. Uhde Thailand – like other globally operating subsidiaries – was able to benefit from the experience and know-how of the German parent company. This made it possible to offer Uhdeʼs complete portfolio with its full array of engineering services not only on the Thai market but also on the entire Southeast Asian market.
In the 1990s Uhde built many large-scale plants in Thailand, including a number of polymer plants – for example for polyethylene, polypropylene and polystyrene, as well as plants for nitric acid/ammonium nitrate, refinery plants and aromatics plants – for TPI, PTT, SCG and other worldclass multinational plant owners. In 2001, a small branch office with 12 employees opened in Map Ta Phut in order to be more customer-responsive and offer constructionsite-related services. There are now more than 250 people working at this office, which has become the center of all operations in Thailand.
In 2015, tk IS Thailand established its center of excellence for specialty chemicals as the result of an acquisition. The technology portfolio that is evolving at this center is marketed and sold worldwide – significant projects to date include Oxiteno (USA) and MOL (Europe).
In keeping with the spirit of the company's former founder Friedrich Uhde, there is no end to the innovation and development processes at tk IS Thailand either: in 2019, the Thai organization will become a center of excellence for modular design and construction, contributing its expertise in particular to the fast-growing business fields of green ammonia and green hydrogen.
