Songwon Industrial Co., Ltd.

Thermoplastic polyurethanes (TPUs) are high performance polymers. Manufacturers of high-quality articles such as wire & cable, film & sheet, tubes & hoses, mobile phone cases, rail pads, tarpaulin and much more take advantage of the significant value provided by our wide range of SONGSTOMER™ TPU polymers to meet the most demanding extrusion, injection molding and calendering requirements.

SONGSTOMER™ TPU polymers are suitable for applications that require excellent transparency and color stability as well as resistance to tearing, cutting and abrasion, to oil and fuel, to weathering and to low temperatures.

Polyurethane laminating adhesives increase productivity of packaging operations. With our expertise in polyurethane laminating adhesive technology, we can help improve operational efficiency and profitability.

Polyurethane ink binders enhance print quality on plastic film packaging. SONGWON is a leading specialist in polyurethane ink binder technology for gravure and flexography printing inks used in flexible packaging laminates.

Polyurethane coatings combine versatility with high quality. Designed for a wide variety of applications ranging from artificial leather items to gloves and shoes, our comprehensive range of HI-THANE™ polyurethanes is distinguished by high wetting properties and low tackiness, making the products particularly suitable for knife, comma, and dip coating processes.

Polyurethane adhesives for artificial leather combine efficiency and comfort. In surface films for artificial leather, our comprehensive range of HI-THANE™ polyurethanes and hot melt adhesives promote high tensile strength and resilience, excellent elongation properties, and outstanding resistance to chemicals, oil, and abrasion.

To help customers deal with the complexity of additivation, SONGWON offers flexible solutions, called “One Pack Systems”, consisting of a multi-component blend of additives integrated into a dust-free, pelletized form.

SONGNOX® OPS are 100% active additive blends, tailored from a wide range of additive products to meet customers’ needs. Homogeneous and highly accurate in composition, the pre-dispersed pellets can be easily processed into a polymer matrix. OPS help to optimize our customers’ compounding processes, improving dosing accuracy, minimizing dust, increasing process reliability and reducing quality control & logistics costs.

Thanks to their high consistency, OPS can be of particular value to a wide range of industries and applications where end-use specifications are critical. Additionally, OPS do not require the use of the carrier materials often needed where separate powder additives are combined.

Phenolic antioxidants (AOs), also known as primary antioxidants, are highly effective, non-discoloring stabilizers for organic substrates that are prone to oxidation, e.g., plastics, synthetic fibers, elastomers and waxes. They act as free radical scavengers and are primarily used to protect the finished product.

Phosphite antioxidants, also known as secondary antioxidants, act as peroxide decomposers, protecting the polymer and ensuring color retention of oxidation-prone organic polymers, especially during processing.

Thioester antioxidants decompose and neutralize hydroperoxides formed through polymer oxidation. Thioesters are used to provide heat aging protection and to preserve color.

Aminic antioxidants help to preserve physical and surface properties, including color, and scorch and heat resistance.

Binary blends are a combination of a primary (phenolic) antioxidant and a secondary (phosphite) antioxidant for optimum stabilization during processing and service life.

UV absorbers (UVAs) provide protection by absorbing energy from UV radiation and, through a reversible chemical rearrangement, dissipate the energy as heat. HALS and UVAs can be used together to achieve optimum UV protection.

Our SONGXTEND® range of innovative stabilization packages solve a number of the key issues our customers face during processing, conversion and end-use life cycles.

SONGXTEND® Stabilizer Solutions provide:

• processing stabilization solutions for PP film & tapes grades
• stabilizer reducing VOC in PP based automotive compounds
• solutions for PP fiber & thin wall injection molded grades

Our highly advanced production processes and technology enable us to tailor our stabilizer solution products to specification.

In applications where plastics are in contact with metal, such as wire and cable insulation or molded components with metal inserts, metal ions can accelerate oxidation, leading to polymer degradation. Metal deactivators inhibit oxidation, thereby increasing the stability of materials such as polyolefins and PVC.
