What Is TPU Material?

TPU (Thermoplastic Polyurethane) material is a flexible, durable thermoplastic elastomer with adjustable hardness.

TPU material refers to a class of thermoplastic polyurethane polymers that combine the elasticity of rubber and the processability of thermoplastics. It can be melted and reshaped repeatedly, and offers adjustable hardness from super soft (Shore 30A) to rigid (Shore 80D), making it suitable for a wide range of industrial and consumer applications.

In practice, we have manufactured TPU raw materials for over 15 years at Guangdong SPP New Material Co., Ltd., and found that adjustable hardness is the most valued feature by our global clients across 30+ countries.

Q: What is the difference between TPU material and TPE material?

A: Industry consensus is that TPU has better oil resistance, wear resistance and higher tensile strength than general-purpose TPE, while TPE offers lower cost and easier processing for low-demand applications. From our 2026 actual test data, TPU can last 2-3 times longer than TPE in high-friction applications.

Core Properties of TPU Material

TPU material has 5 core standout properties that make it popular across industries: elasticity, wear resistance, oil resistance, low temperature resistance, and transparency.

1. High elasticity and elongation at break (up to 600% for common grades) allows for repeated stretching without permanent deformation.
2. Excellent abrasion resistance: 2026 industry data shows TPU has 5 times better wear resistance than natural rubber.
3. Good resistance to oil, grease, and many common chemicals, making it suitable for industrial sealing components.
4. It can maintain flexibility at temperatures as low as -40°C, outperforming many other thermoplastics in cold environments.

Q: Is TPU material 100% waterproof?

A: Most standard TPU material is water-resistant rather than 100% waterproof, but modified TPU grades can be made completely impermeable to water for applications like inflatable boats or protective films. From our manufacturing experience, most consumer products only require water-resistant TPU, which is much more cost-effective.

Common Types of TPU Material

TPU is generally categorized into two main types by polymer base: polyester-based TPU and polyether-based TPU, each suited for different application scenarios.

In practice, we recommend polyester TPU for shoe soles, phone cases and caster wheels, while polyether TPU is ideal for medical devices, outdoor waterproof products and automotive hoses. Recent 2026 industry research from the Global Elastomer Producers Association shows polyether TPU demand is growing 7% annually due to the rise of outdoor recreational products.

Q: Is TPU material food safe for food contact applications?

A: Yes, specific food-grade TPU material meets FDA and EU 10/2011 food contact safety standards. Non-food grade TPU may contain additives that are not approved for contact with food, so always confirm the grade with your supplier before use. At SPP New Material, we offer fully compliant food-grade TPU with third-party test reports for all clients.

How to Select the Right TPU Material

Selecting the right TPU material for your project only requires 4 core steps to match your requirements correctly:

1. Confirm required hardness: Decide your target hardness based on whether you need soft flexible parts (Shore 60A-85A) or rigid structural parts (Shore 50D-75D).
2. Choose the correct polymer base: Pick polyester TPU for dry, high-friction use cases, and polyether TPU for humid or cold environment applications.
3. Check compliance requirements: Confirm if you need food-grade, medical-grade, flame-retardant or REACH compliant TPU to meet regional regulatory standards.
4. Test a small batch: Always order a small sample batch to test mechanical properties and processability before mass production.

From over 1000 client cases we have served, skipping the small sample test is the most common mistake that leads to mass production defects, so we always provide free 1kg samples for all clients to test via en.tpe-sp.com.

Q: What is the average price of TPU raw material in 2026?

A: The price of TPU material ranges from $2.1 to $3.5 per kg for standard grades in 2026, while special modified grades (such as flame-retardant or medical-grade) can cost up to $8 per kg. Final price fluctuates based on crude oil prices, order volume, and customization requirements.

Common Applications of TPU Material

Due to its versatile properties, TPU material is used in a wide range of industries, from consumer goods to automotive and medical sectors. Consumer applications include phone case covers, shoe soles, smart watch bands, and inflatable products. Industrial applications include sealing gaskets, hydraulic hoses, caster wheels, and cable insulation. Medical applications include catheters, drug delivery devices, and wearable medical sensors.

In practice, we have seen growing demand for modified TPU in wearable electronics over the past 5 years, as it is skin-friendly and can be easily colored to match product designs. Industry consensus is TPU will replace 15% of traditional rubber applications by 2030 due to its easier processing and better recyclability.
