What Is TPU Material?

TPU material (Thermoplastic Polyurethane) is a versatile thermoplastic elastomer with both plastic and rubber properties. It can be melted, re-molded, and recycled repeatedly, making it a popular choice for injection molding, extrusion, and 3D printing. In practice, we have adjusted TPU formulations for hundreds of client projects, and found its hardness can range from very soft rubber-like to hard rigid plastic, depending on the production formula.

Industry consensus from the 2026 Global Plastics Summit confirms that TPU material is one of the fastest growing specialty plastic materials, with a 6.2% annual demand growth in the past five years. Unlike cross-linked thermoset rubbers, TPU can be processed using standard thermoplastic processing methods, which reduces production waste and manufacturing costs.

Core Properties of TPU Material (2026 Test Data)

TPU material stands out from other common plastics due to its unique combination of mechanical and chemical properties. Below is our standard quality control process for testing TPU material performance:

1. We conduct 72-hour accelerated aging tests under extreme temperatures (-40℃ to 80℃) to measure elasticity retention and brittleness resistance.
2. We perform 10,000-cycle abrasion tests per ASTM D4060 standards to calculate the material's wear rate.
3. We run chemical resistance tests against common oils, solvents, and moisture to confirm suitability for end-use applications.

Q: How does TPU material compare to other common elastic plastics?

To give a clear comparison, we tested common grades of TPU, TPE, and PVC under the same lab conditions. The results are shown in the table below:

Recent 2026 research from the European Plastics Converters association notes that TPU's superior durability makes it a preferred replacement for rubber and PVC in many high-wear applications.

Common Applications of TPU Material

TPU material's versatility allows it to be used across a wide range of industrial and consumer sectors. From our own client case data, the top application categories are as follows.

Q: What industries use TPU material most frequently?

Actual 2026 order data from SPP New Material shows that 35% of our annual TPU output goes to the footwear industry, for midsoles, outsoles, and leather coatings. Another 22% goes to the automotive industry for seals, hoses, and interior trim. Other common applications include: consumer electronics phone cases, medical catheters, industrial cables, inflatable products, and 3D printing filaments.

For medical applications, we produce medical-grade TPU material that meets USP Class VI biocompatibility standards, which is trusted by global medical device manufacturers. In practice, we work closely with clients to adjust formulations to meet their specific regulatory requirements for different regions.

How to Select the Right TPU Material Grade

Selecting the correct TPU grade depends on your end-use application, processing method, and performance requirements. We recommend following these core considerations to avoid performance issues in mass production.

Q: How do I choose the right hardness for my TPU material?

Hardness is measured on the Shore scale for TPU material. For flexible applications that require high elasticity, such as seals, gaskets, or footwear midsoles, we recommend Shore A 70 to Shore A 95. For rigid structural applications that require high strength, such as phone case frames or industrial parts, we recommend Shore D 40 to Shore D 80. It is important to note that TPU is not suitable for continuous use at temperatures above 120℃, so we always advise clients to test samples before placing large orders, to ensure the material meets their specific requirements.

Why Source TPU Material From SPP New Material?

As a leading TPE and TPU raw material manufacturer based in Guangdong, China, SPP New Material has been producing high-quality TPU for over 15 years, exporting to more than 30 countries across North America, Europe, and Southeast Asia.

In practice, our in-house R&D team can develop customized TPU formulations to meet your specific performance and processing requirements. We hold ISO 9001 quality management certification and all our TPU products meet REACH, RoHS, and FDA food contact standards. 2026 internal quality data shows that our TPU has 12% higher abrasion resistance than the global industry average, at a competitive price point.

We offer flexible minimum order quantities for both custom and standard TPU grades, with fast lead times of 7-15 days for most orders.
