Tin Intermediates, PVC Additives, and Polymers
A number of SONGWON’s businesses are grouped under TPP, which stands for Tin Intermediates, PVC Additives and Specialty Polymers:
- Tin Intermediates are designed for coating industry applications such as automotive paints, glass and tin coatings, as well as for catalysts used in various plastics.
- PVC Stabilizers and Plasticizers for the global PVC manufacturing industry provide protection against damage caused by heat and during processing, for example in lubrication systems.
- Specialty Polymers, such as Polyester Diols, “Solution” (thermosetting and/or thermoplastic) Polyurethanes (PUs) and Thermoplastic Polyurethanes (TPUs) based on esterification technology, are used in ink binders, adhesives, and other applications requiring solution PUs and TPUs.
Tin Intermediates & Stabilizers
Extensive and long-standing experience in tin intermediates has enabled SONGWON to make use of its expertise in alkyl tin oxides to refine processes for producing organo-tin compounds based on butyl and octyl oxide (DBTO and DOTO). Applications include electrodeposition coatings, tin catalysts and stabilizers for PVC.
Butyl and octyl oxides are the main catalysts used in electrodeposition coating technology, which is applied extensively in the global automotive industry.
Tin catalysts based on butyl and octyl oxides support various chemical reactions such as esterification.
Tin stabilizers prevent degradation of PVC resins, which require particularly high heat resistance.
Customers can select from a wide range of SONGWON’s SONGCAT™ Organo-Tin Intermediates, depending on applications and requirements.
The third most widely produced synthetic plastic polymer after polyethylene (PP) and polypropylene (PE), polyvinyl chloride (PVC) comes in two basic forms: rigid and flexible. PVC is used in construction applications such as pipes, doors and windows, as well as in the packaging, automotive, household and furniture, and medical sectors. Flexible PVC today often replaces rubber in plumbing, electrical cable insulation, imitation leather, signage and inflatable products.
Since PVC is heated to soften it during processing, it needs to be stabilized to prevent decomposition resulting from elimination of the hydrogen chloride it contains. Stabilizers help to improve productivity and enhance the resistance of PVC to light, weathering and heat aging, making end products more durable and preserving their appearance. They are almost always supplied as application-specific blends and their main components are metal soaps, metal salts and organo-metal compounds. The choice of heat stabilizer depends on various factors, including technical requirements, regulatory approval and cost. As a leading manufacturer of PVC Additives SONGWON is your competent supplier.
One Pack Systems (for PVC)
One pack systems allow easy, accurate dosing
SONGSTAB™ one pack systems for PVC stabilization are complex formulations comprising blends of stabilizers and lubricants. They allow efficient and accurate additivation by combining the required additives in a single package for easy dosing.
SONGWON offers tailor-made solutions for all applications, including extrusion, calendering and injection molding, etc.
Mixed Metal Stabilizers
Mixed metal stabilizers optimize PVC processing
Mixed metal stabilizers, essential for PVC processing, are one pack systems available in liquid form, depending on the formulation and end application.
Metal Soap Stabilizers
Metal soaps are used in non-toxic compounds
Metal soap stabilizers, based on calcium, zinc and magnesium, act as acid scavengers and are used in non-toxic compounds. Applications include lubricants, release agents and water repellents.
Organo-tin stabilizers offer a broad spectrum of applications
Organo-tin stabilizers have excellent heat stability, anti-weathering properties and transparency. They are highly compatible with all other types of additives used in PVC. With its butyl tin, octyl tin and methyl tin ranges, SONGWON offers organo-tin stabilizers for a broad spectrum of applications, especially rigid plastic goods.
Auxiliary Stabilizers & Lubricants
Auxiliary stabilizers & lubricants optimize stabilization and other properties
Auxiliary stabilizers and lubricants improve heat stability, anti-weathering properties and transparency as well as enhancing color when used with other stabilizers. They help to optimize welding, gluing and printing properties.
Plasticizers improve flexibility and durability of PVC products
Mainly used for PVC, plasticizers improve the flexibility and durability of plastic end products. They also act as softeners, extenders and lubricants.
SONGCIZER™ plasticizers are suitable for applications requiring good workability as well as resistance to heat and low temperatures, light and viscosity fluctuations. They are primarily used for low-temperature-resistant PVC, as a component in synthetic lubricants, and in high- and low-temperature-resistant greases.
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
Converters working in the plastic film packaging industry benefit from the excellent physical properties and technical attributes of HI-THANE™ laminating adhesives, sealants curing agents. 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
Printing ink manufacturers can produce high quality print on plastic film packaging thanks to the excellent physical properties and technical attributes of HI-THANE™ ink binders. 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. HI-THANE™ polyurethane coatings are one component materials that form films with excellent stability at low temperature, whether applied by dry or wet processing methods.
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. At the same time, they help to impart a soft, comfortable feel to the material.
Polyester polyols can be customized with flexibility and responsiveness
Formulators can achieve specific properties geared to the final application with our broad range of high-performance aliphatic polyester polyols for the synthesis of high-quality coatings, adhesives and polyurethane elastomers. SONGSTAR™ polyester polyols can be tailor made to meet various ‒ including highly demanding ‒ requirements.
