Speaking of the two major materials in injection molding products: TPU and TPR, I have to mention them. They play an important role in the injection molding industry. So, their TPR materials and silica gel materials have similar hardness and physical properties, and are environmentally friendly soft compounds. What are the differences between them?
Injection molded TPU has a wide hardness range (60ha-85hd), wear resistance, oil resistance, transparency and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen free flame retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields.
Injection molding product TPR not only has the characteristics of thermoplastic processing, but also has the rubber elastic properties of vulcanized rubber. Thermoplastic rubber appeared in the early 1950s, but it was not used until the 1970s. A new industrial raw material system has been formed, which is called “the third generation rubber”.
TPU and TPR can be used in many injection molding products. TPR will be a little better on products requiring slightly higher precision.
So, the application of TPU and TPR injection molding products is introduced here. Can you distinguish them now?
