PVC-Stabilizer Sector 

One of the most commonly-used thermoplastic products in the world is Polyvinyl chloride (PVC). Due to its nature, PVC is a material which cannot be turned into a final product without additives. One of the most important inputs required for the procession of PVC is stabilizer. Such additives play a decisive role in the manufacturing of PVC-based products, provide important features such as color consistency, resistance and surface smoothness and ensure that products can be processed under ideal conditions.  

Annually, 40 million tons of PVC are consumed in the world and accordingly, the estimated stabilizer market is nearly 1.2 million tons. In Turkey, nearly 900 thousand tons of PVC are consumed per year and it is necessary to use nearly 30 thousand tons of stabilizer for the production of PVC at this volume.

OYAK Group together with the affiliated Akdeniz Kimya and Chemson Group is the largest global producer and has the largest market share in terms of the production of stabilizer and other additives which are the most indispensable inputs of the PVC industry.

Akdeniz Kimya is one of the rare integrated corporations of the world which can produce calcium/zinc and lead-based intermediate raw materials for stabilizer by itself with an annual capacity of 130 thousand tons.  Akdeniz Kimya which is the leading company for responding to the consumption of stabilizer in Turkey also exports to 96 countries in 5 continents.

Austria-based Chemson Group, another affiliate of OYAK Group engaging in activities in the same field, is one of the important players at global scale with an annual capacity exceeding 170 thousand tons and production facilities spread in 5 continents.


Specialty Alumina Sector

Specialty alumina, which is manufactured so as to benefit from the additional features such as heat resistance, mechanical stability, electrical insulation and abrasion resistance of alumina, the main raw material in the production of aluminum metal, is used in many sectors and production processes. Major areas of use for the specialty alumina are refractory production, ceramics and polishing industry. Global market size of the specialty alumina is 2.8 million tons as of 2015.

Almatis Group which is an affiliate of OYAK Group and a global player in the sector is by far the global leader in the relevant sector.
