As SASA s one of the base products, Polyethylene Terephthalate (PET) polymer is a thermoplastic polymeric material formed by the interaction of dimethyl terephthalate (DMT) or terephthalic acid (PTA) with monoethylene glycol (MEG).PET polymer products in SASA s product portfolio are available for the following end uses: Film All kinds of film applications, especially food packaging Injection Manufacturing of all kinds of plastic materials Industrial Industrial applications requiring high tenacity, such as tire cord manufacturing Medical Parts of medical equipment and medical materials Textile Manufacturing of staple/filament fibers and nonwoven For products manufactured for the film industry, conductivity, which is a very important parameter, can be adjusted very sensitively. In addition to the standard film grade products, there are silica also masterbatch products containing different types of silicas in the product portfolio. The most common catalyst of PET production is antimony (Sb). Antimony-free PET products for differentiated end uses can be found in SASA s product portfolio. Titanium dioxide (TiO2) is used as a delustrant in products, especially for textile end uses. TiO2 filling is possible between 0.0% and 1.5% by weight. PET with black color can be manufactured by adding carbon black during polymerization process. The target viscosity (IV) value in SASA s PET production technology is 0.64 dL/g. However, it is possible to make amorphous production between 0.48 0.70 dL/g IV. Additionally, it is possible to manufacture high IV products, such as 1.20dL/g IV with the existing SSP equipment.SASA can produce all of its products as 100% amorphous, semi crystalline or SSPed.Products are shipped in chips form by bulk containers or big bags. You can see our differentiated polymer products with the properties developed or modified such as dyeability, hydrolytic resistance, flame retardancy, melting point, glass transition point and water solubility in the Advanced Polymers section.

PET resin is a polymer manufactured from terephthalic acid (PTA), isophthalic acid (IPA) and ethylene glycol (EG) raw materials. SASA included the bottle-type PET Resin product group in its portfolio with the new MTR (Melt to Resin) facility with a capacity of 315 kt/year, commissioned in 2020. Thanks to the MTR technology, unlike the traditional two-stage method, bottle-type PET Resin manufacturing obtains a high viscosity product at the desired level with a single-stage process.

After the polymerization, the chips, which are granulated in underwater chips cutting units, take a spherical form. This spherical form offers users several benefits such as: Low energy consumption, low carbon emission Low dust content Homogeneous IV distribution Low acetaldehyde formation Easier flow, less dust formation compared to cylindrical form Main Applications: PET bottles; carbonated and still mineral waters, soft drinks, oils PET containers; Food, Detergent, Cosmetic, Pharmaceutical PET Thermoforms PET Sheets

SASA s other base product is Polybutylene Terephthalate (PBT) polymer. PBT is a thermoplastic polymeric material formed as a result of polymerization by the reaction of dimethyl terephthalate (DMT) with 1.4 butane-diol (BDO).PBT polymer products in SASA s product portfolio are available for the following end uses: Injection Production of all kinds of plastic materials Industrial Industrial applications requiring high tenacity Medical Parts of medical equipment and medical materials Textile Staple/filament fibers and nonwoven production The target viscosity (IV) value in SASA s PBT production technology is 0.90 dL/g. However, it is possible to make amorphous production between 0.70 1.00 dL/g IV. In addition, it is possible to manufacture high viscosity products, such as 1.20dL/g IV with the existing SSP equipment. PBT amorphous polymer is an inherently crystalline polymer. Therefore, there is no need for an additional crystallization process. SASA can produce all of its products as crystalline or SSPed. Titanium dioxide filling for textile end uses is also possible for PBT products, as well as PET products. Black PET can be manufactured by adding carbon black directly during the polymerization process. SASA can monitor the viscosity of PBT polymer products with IV, as well as MVR (cm3/10min). Products are shipped in chips form by bulk containers or big bags.

As an integrated producer of polymer and chemical, SASA has the biggest DMT production capacity in the world with 280,000 tons/year. Dimethyl terephthalate is the main monomer of PET and PBT polymers. The majority of DMT that SASA produces is used for the production of SASA s other products and the residual capacity is sold in solid forms. The main end use of DMT is polyester production. DMT is shipped as briquettes or flakes in big bags. The products are shipped to many points in the world by 20 and 40 containers.

Thermoplastic polyester elastomers combine the properties of vulcanized rubbers with the easy processability of thermoplastics. Hard polyester molecules and soft polyether molecules form the molecular structure of TPEs. The hardness of the material is determined by the ratio of soft molecules to hard molecules. These are flexible products that have high flexing endurance, energy absorption and abrasion resistance. Easy and economic processability and a long life-cycle time are among their advantages. The heat resistance of TPEs is much higher than those of polyolefin, polystyrene and polyurethane. TPEs can be used in various end uses that require flexibility and high abrasion resistance, in the automotive and machinery industries. Products are shipped in chips form by big bags and bulk containers.

In addition to base PET and PBT polymer products, specific homo-polymer or co-polymer products for special end uses are also available in SASA s product portfolio. Flame Retardant Polyester (FR) Flame retardant co-polymer PET products need prolonged exposure to flame for burning compared with standard PET products, and do not have a tendency to spread flames. This product is used as upholstery material in public transportation vehicles such as buses, trains and planes and in public areas such as shopping centers, cinemas and theaters. Halogen-free phosphor-based co-monomer is directly linked to the polymer chain. Its phosphor content is 5500 ppm. Cationic Dyeable Polyester (CD) Standard PET polymer can only be dyed by dispersion dyes once the polymer is formed.Dispersion dyeing entails high cost, requires dyeing equipment with high pressure, and has limited color range. The cationic dyeable copolymer PET product is developed to eliminate these disadvantages.Product becomes dyeable by cationic dyes with the help of a functional co-monomer linked to the main polymer chain. The base end use is textile manufacturing. Low Melt Polyester There are both PET and PBT copolymer products in SASA s product portfolio that have a lower melting point than standard polymers. They are used mostly as mono-component or bi-component binder fibers in non-wovens. The melting temperature of the product (Tm) can be adjusted between 110°C and 250°C, and similarly the glass transition temperature (Tg) can be adjusted between 20°C and 80°C. Hydrolysis Resistant Polyester After the polymerization of polyester, carboxyl end groups remain in the structure of polymer chains. These carboxyl end groups cause hydrolytic degradation when the product is exposed to humidity or water for a prolonged time. SASA s hydrolysis-resistant polyester product in its product portfolio does not have hydrolytic degradation. Hydrolysis Resistant Polyester is developed to overcome the above-mentioned effects of carboxyl end groups and thus the product life is prolonged. The main end uses are all applications that contact with water consistently. Water Soluble Polyester Water-soluble polyester is a wax like product that is in solid form under room conditions and dissolves in water. It does not have a properly cut shape due to its low glass transition temperature. Water-soluble polyester is used as coagulator in stone washing of denim products, in dyestuffs, binders and cosmetics. Water-soluble polyester is used as a coagulator in stone washing of denim products, in dyestuffs, binders and cosmetics. Polyethylene naphthalate (PEN) PEN is a thermoplastic polymeric material which is formed by the polymerization resulted from the interaction of naphthalate dicarboxylic acid (NDC) with monoethylene glycol (MEG). PEN has a higher glass transition temperature (Tg) than PET. Thanks to its high heat resistance and high mechanical properties, PEN is used in the production of flat screen TVs, printed circuit, reusable food packages, etc. Co-polymerization is possible and the co-polymerization degree can be adjusted according to the end use.
