PVC-Stabilizer Sector

Polyvinyl chloride (PVC), one of the most commonly used thermoplastic products in the world, is a material that cannot be turned into a final product without additives. One of the most important inputs required for processing PVC, one of the most valuable products of the chemical industry, is stabilizer.  Such additives play a decisive role in the manufacturing of PVC-based products, and play a critical role in the development of the final product with desired strength and properties such as color consistency, durability and surface smoothness.

Together with the affiliated Akdeniz Kimya and Austria-based Chemson Group companies, OYAK Chemicals Group is the largest global producer and has the highest market share in the production of stabilizers, one of the most indispensable inputs of the PVC industry, and other additives. The additives produced by the group are used for the manufacturing of final products in several industrial areas such as building, construction, electric-electronic and automotive. Production of the stabilizers, the additives of products such as PVC based hard window and structural sections, pipes, cables and surface coatings available in the said sectors, is carried out by our Akdeniz Kimya and Chemson Group companies.

Akdeniz Kimya is one of the rare integrated corporations of the world which can produce calcium/zinc and lead-based intermediate raw materials for stabilizers and acrylic based PVC additives with a total annual final product capacity of 130 thousand tons.  Akdeniz Kimya, the leading company for covering to the consumption of stabilizer in Turkey, also exports to more than 100 countries in five continents.

Specialty Alumina Sector

Specialty alumina is obtained by subjecting alumina, which is used as the primary raw material for the production of aluminum metal, to a series of additional refining processes. Providing additional features such as heat resistance, mechanical stability, electrical insulation and abrasion resistance to the products where it is used as a raw material, specialty alumina is a raw material with critical importance in many sectors and production processes. Major areas of use for the specialty alumina are refractory production, ceramics and polishing industry.

Netherlands based Almatis Group, a group company of OYAK and a global player in the sector, is by far the global leader in the sector. With operations in the USA, Germany, Netherlands, Japan, China, India, Brazil and Singapore, Almatis has nine production facilities in six countries, eight sales and supply chain centers in six countries, as well as six application and R&D labs.
