China TPU Elastomer Additives Supplier - High-Quality Thermoplastic Polyurethane Factory Products
Product Description
Thermoplastic polyurethane elastomer (TPU), with its excellent properties and wide application, has become one of the important thermoplastic elastomer materials, whose molecules are basically linear with little or no chemical crosslinking.
There are many physical crosslinks formed by hydrogen bonds between linear polyurethane molecular chains, which play a strengthening role in their morphology, thus giving many excellent properties. These excellent properties make thermoplastic polyurethane widely used in many fields such as footwear, cable, clothing, automobile, medicine and health, pipe, film and sheet.

Frequently Asked Questions
What is TPU and why is it considered an important thermoplastic elastomer material?
TPU (Thermoplastic Polyurethane Elastomer) is a versatile polymer material with molecules that are basically linear with little or no chemical crosslinking. Its importance stems from the physical crosslinks formed by hydrogen bonds between molecular chains, which provide excellent mechanical properties including high modulus, high strength, outstanding wear resistance, and broad chemical resistance — making it suitable for a wide range of industries.
What types of TPU additives does your company offer?
We offer a comprehensive range of TPU additives including Antioxidants (YIHOO AN445, YIHOO AN445SP, YIHOO AO80), UV Absorbers (YIHOO UV1, YIHOO UV B75), and One Pack Products that combine antioxidants, light stabilizers, and flame retardants in a single formulation tailored to customer requirements.
How do your TPU additives help prevent yellowing and aging?
Our TPU additives work through a combination of antioxidant protection and UV absorption mechanisms. The antioxidants prevent oxidative degradation at the molecular level, while the UV absorbers shield the material from ultraviolet radiation — both of which are primary causes of yellowing and aging. This dual-action approach has been validated across many high-end applications over the years.
Can you provide customized One Pack formulations for specific TPU applications?
Yes. We offer customized One Pack products that can be tailored to meet specific customer requirements, containing a combination of antioxidants, light stabilizers, and flame retardants. Customers can also select from our existing proven formulations to simplify their production process and ensure consistent quality.
What industries and application fields are your TPU additives suitable for?
Our TPU additives are suitable for a broad spectrum of industries and applications, including footwear, cable manufacturing, clothing and textiles, automotive components, medical and healthcare products, pipes, films, and sheet materials. Beyond TPU, our broader product series also covers PA, PVC, PC, coatings, cosmetics, and automotive trim applications.
What is the difference between YIHOO AN445 and YIHOO AN445SP?
Both YIHOO AN445 and YIHOO AN445SP share the same CAS number (36443-68-2) and are stereostylized phenolic antioxidants. The key difference is that YIHOO AN445SP is a super fine powder version of AN445, with adjustable mesh size according to customer requirements — making it ideal for applications where finer particle size distribution is critical for processing or performance.
