Mechanical Properties

Nylon 12 offers very high tensile strength making it ideal for producing functional prototypes and end-use parts that need to endure mechanical stress and load-bearing requirements. In addition to its strength, Nylon 12 also exhibits excellent impact resistance. It can absorb and dissipate energy effectively, making it suitable for applications where parts may experience sudden shocks or collisions. This property is especially valuable in the automotive industry, where components may encounter dynamic forces during operation. It is is capable of maintaining its shape and resists deformation under applied loads. This property ensures dimensional stability and precision in printed parts. It is particularly advantageous in applications that require accurate geometries or tight tolerances.

Chemical Compatibility

Thermoplastic Polyurethane demonstrates good chemical compatibility, particularly resistant to oils, greases, and various solvents. Its resistance to abrasion and wear also makes it suitable for environments where exposure to chemicals is common. However, it's important to note that TPU may not be as resistant to strong acids, bases, and some organic solvents. This balance of chemical resistance and vulnerability makes TPU a preferred choice in industries like automotive, where it's often used for parts exposed to oils and fuels, but less ideal for applications involving harsh chemicals or extreme environments.

Thermal Properties

Thermoplastic Polyurethane (TPU) offers good temperature resistance, typically between -20°C to 80°C, and low thermal conductivity, making it an effective insulator. Although its heat deflection temperature isn't very high, leading to potential deformation under extreme heat, its melting point is well-suited for SLS printing processes. Additionally, TPU exhibits relatively low thermal expansion, ensuring better dimensional stability across various temperatures. These characteristics make TPU a versatile material in applications that require flexibility, durability, and thermal stability, such as in automotive and consumer products. 

Applications

The strength and flexibility of TPU 88A makes it suitable for a variety of end-use applications. It's extensively used in creating flexible parts such as gaskets, seals, and hoses, as well as in the production of footwear, especially for intricate shoe soles and insoles. TPU's elasticity and strength make it ideal for protective gear, like custom-fit phone cases or impact-resistant sporting goods. In automotive manufacturing, it is commonly used parts for armrests, dashboard elements, and door handles, providing both aesthetic appeal and functional reliability. The durability and resistance to wear make it an ideal choice for industrial tools such as pipes and grippers, ensuring longevity and effective performance in demanding environments.
