Comparison between TPU and other elastic materials

When considering elastic materials, various options come to mind. Natural rubber, silicone, and TPU (Thermoplastic Polyurethane) are among the most common. However, each material has its unique properties and applications. This article aims to contrast TPU with other prevalent elastic materials, assisting readers in understanding the advantages and limitations of each.

1. Natural Rubber:

Natural rubber is praised for its exceptional elasticity and flexibility. It also offers excellent shock resistance and wear-resistance. However, compared to TPU, natural rubber is more sensitive to UV rays, oxygen, and temperatures, making it prone to aging. Furthermore, its resistance to oils and certain chemicals is not commendable.

2. Silicone:

Silicone is renowned for its heat-resistance, cold-resistance, UV-resistance, and anti-aging characteristics. Moreover, it's food-grade safe and often used in kitchen utensils and medical equipment. While silicone is soft, its elasticity and wear-resistance are inferior to both TPU and natural rubber.

3. TPU:

TPU combines many of the benefits of both natural rubber and silicone. It boasts outstanding wear-resistance, elasticity, and anti-aging properties. Its resistance to oils, chemicals, and UV rays is also commendable. Furthermore, due to its thermoplastic nature, TPU can be easily molded using various methods. Although TPU has many advantages, its cost is relatively higher, especially when compared to natural rubber.

So, how does one choose the appropriate material? It entirely depends on the application. If you require a food-grade safe material, silicone might be the best bet. If you need a material with high elasticity and flexibility, natural rubber might be more fitting. However, for many modern applications like sports shoes, high-performance elastic bands, or industrial components, TPU, with its comprehensive performance, has become the go-to. TPU elastic tape, also named mobilon tape is one application with large number in apparel industry.

In conclusion, while each material has its unique benefits and limitations, TPU, with its superior performance and versatility, often stands out as an excellent choice in many scenarios. Of course, factors like cost, availability, and specific application needs should also be considered when selecting a material.

Each material has its place. Understanding the properties and strengths of each can aid us in making more informed decisions.
