Thermoplastic polyurethane (TPU) refers to polyurethane polymers which exhibit thermoplasticity; that is, they become pliable when heated and harden when cooled. This is in contrast to most polyurethanes, which are thermosets that harden irreversibly.

TPU and rubber are both elastic plastic materials, which are both widely used in daily life and industrial field. But they are absolutely different materials. TPU, with full name Thermoplastic polyurethanes, is a type of sustainable eco-friendly material. It’s a man-made material.

Thermoplastic polyurethane (TPU) is a melt-processable thermoplastic elastomer with high durability and flexibility. It provides several physical and chemical property combinations for demanding applications. Some examples include: It has properties between the characteristics of plastic and rubber.

Used either as a malleable engineering plastic or as a replacement for hard rubber, TPU is renowned for many things including its: high elongation and tensile strength; its elasticity; and to varying degrees, its ability to resist oil, grease, solvents, chemicals and abrasion.

Dec 5, 2024 · Polyurethane, particularly thermoplastic polyurethane (TPU), tends to resist UV degradation much better than traditional rubber, which is prone to cracking and deterioration when exposed to sunlight. This makes polyurethane an ideal choice for outdoor applications , such as automotive coatings , exterior sealants , and exposed machinery parts .

Jun 5, 2023 · TPU (thermoplastic polyurethane): The burning flame is yellow, with slight sizzling and explosive sound; it has a special odor (the smell of ammonia); TPU is transparent particles, and can also be matched with white or black. The hardness range is 60A~80D. Rubber (vulcanized type):

Thermoplastic polyurethane (TPU) is a thermoplastic elastomer that is commonly used in injection molding and 3D printing. It is a rubber-like material with a low shore hardness of 85-95A, meaning it is relatively hard, but still flexible.

Feb 13, 2025 · Thermoplastic Urethane (TPU) is better suited for high-temperature applications compared to Thermoplastic Rubber (TPR). TPU has a broader temperature range, performing well from -40°C to 125°C, and exhibits superior thermal stability and durability.

Dec 23, 2022 · What is TPU? TPU, or thermoplastic polyurethane, is a broad classification of polyurethane polymers that share properties such as elasticity, wear resistance, and very high chemical compatibility with oils. The materials are thermoplastic, making them suitable for injection molding.

Oct 4, 2023 · TPU or Thermoplastic Polyurethane, represents a class of plastics synthesized through a polyaddition reaction involving a diisocyanate and one or more diols. Its versatile nature allows it to function as a soft engineering plastic or an alternative to rigid rubber materials.
