For those engaged in the sales of thermoplastic elastomers, it is important for TPE/TPR material manufacturers to maintain good relationships with customers. In the process of communicating with customers, if one has a professional understanding of their own products, it will make customers more trusting. Today, the editor will share a simple picture of the first time they receive a sample of an elastomer and distinguish whether this sample is made of TPE or TPR material. There are materials similar to TPE/TPR on the market, such as PVC/TPU/rubber, etc. In fact, a simple and clear way to distinguish them is to use a fire machine to burn them, and identify which material it is by smell and looking at the flame

A TPU material. TPU material has a yellow flame with a distinctive odor and a slight explosion sound after combustion. TPU is a transparent particle with a hardness range of 60A-80D.

Two TPV materials. After combustion, the flame of TPV material appears yellow on top and blue on the bottom, with a smell of petroleum, and the smoke produced is relatively light. The TPV material consists of yellow particles with a hardness range of 50-100A

3： PVC material, after combustion, the flame of PVC material appears yellow on top and green on the bottom, with a strong odor and produces thick smoke. Common PVC materials include transparent and pink materials, with a hardness range of 0-100A.

4： Rubber. Rubber has a yellow flame and a strong burning odor after combustion. Generally speaking, vulcanized rubber products are usually black, but there are also yellow or white colors, with a hardness range of 50~80A.

5： TPE/TPR materials. TPE materials have a yellow or yellow on top and blue on bottom flame after combustion. TPE materials with different hardness and substrates produce different odors and smoke, but all have a faint aromatic aroma. TPE materials come in transparent, natural, and black colors, as well as other colors that can be matched. The range in India is between 0-100A. TPE materials have a soft and smooth touch, and good resilience. The above is a simple method shared by TPE material manufacturer editors for identifying TPE materials.
