What Are The Characteristics Of TPU Foam Material
As the name implies, TPU foam material is a product formed by foaming TPU (thermoplastic polyurethane elastomer), commonly known as "popcorn". Generally, it can be divided into physical foaming and chemical foaming. Physical foaming refers to compressing gas into raw materials and then changing the pressure and temperature to foam the product without chemical reaction, so it is an environmentally friendly material; chemical foaming Foam refers to the chemical change of the chemical foaming agent when heated, thereby decomposing and generating gas, which promotes the foaming of rubber and plastic polymers. The foaming ratio of TPU foam material can be as high as 8 times; it is non-toxic, tasteless, degradable, and more environmentally friendly; it has high strength, heat resistance, wear resistance; shock absorption, light and comfortable, high resilience, antibacterial, and breathable.
Features of TPU foam material:
High wear resistance: It can be seen from the Taber wear index comparison of tpu and other materials.
Wide range of hardness: By changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the products still maintain good elasticity.
High mechanical strength: The bearing capacity, impact resistance and shock absorption performance of tpu products are outstanding.
Good processing performance: tpu can be processed by common processing methods of thermoplastic materials, such as injection, extrusion, calendering, etc. At the same time, the co-processing of TPU and some polymer materials can obtain polymer alloys with complementary properties.
Outstanding cold resistance: The glass transition temperature of tpu is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees. Oil, water and mold resistant. Good recycling.
