What is the difference between TPR material and silicone?

TPR material is a thermoplastic rubber material in the shape of particles, usually spherical particles, ellipsoidal particles, and fine round strips, with a bright surface and good elasticity, resilience, shrinkage, wear resistance, and weather resistance. However, for many people who are new to TPR materials, it is easy to confuse them with silicone. TPR materials and silicone are different kinds of materials. They have common characteristics, but there are also certain differences. So, where is the difference between TPR material and silicone?

The differences between TPR materials and silicone are as follows:

  1. Hardness.

TPR material hardness range, its hardness can be regulated in 0A-70D. TPR application is also wider than silicone, commonly used in adult products, casters, shoe materials, toys, etc.

  1. Processing performance.

TPR material has the resilience of rubber and plastic processing performance, without vulcanization, with available thermoplastic injection molding machine can be processed. In contrast, silicone in processing performance is not TPR good. Production and processing are difficult but also easy to scrap.

  1. Recycling.

TPR material scrap edge can be recycled, and silicone can not be recycled. TPR material protects the environment, saves the earth’s resources, and responds to the country’s environmental protection green advocacy.

TPR material is a kind of thermoplastic rubber, while silicone is a highly active adsorbent material, which is an amorphous substance. Although they belong to the same environmentally friendly materials, they will not cause harm to the human body, the two have a lot of similarities, but their characteristics are very different. In future development, TPR materials will replace silica gel in some fields from the perspective of cost performance.
