There are many soft gelatinous substances in daily life. If you carefully observe these soft gelatinous substances, you will find that the surface is marked with tpu. Many people don't know much about this material, so tpu is silicone? What is the material of pu? What is the difference between PU and silicone? Let's take a look together.

Tpu is not silicone, but thermoformed polyurethane elastomer, which has many advantages such as wear resistance, flexibility and high transparency, so it is used in all aspects of life. Tpu is a kind of material between plastic and silica gel, which is very different from silica gel. Their differences are as follows:

1, different hardness: silica gel and tpu have different hardness, so silica gel feels softer and better; Tpu feels hard and belongs to a relatively hard material; Because of their different hardness, their contractibility is also different. Silica gel is elastic and easy to stretch, so if silica gel and tpu are put together, it is easy to distinguish by hardness. The softer silica gel is the harder tpu.

2. Different materials: Silica gel and tpu are very different because of their different materials. Silicone products are easy to clean after encountering dirty things, but once the tpu surface is stained, it is difficult to clean.

3, feel different: tpu products will feel very smooth and feel good; Silicone products are made of environmentally friendly materials such as silicon dioxide. Although it is soft, it feels like frost and is not very smooth.
